Abstract

A connecting structure includes: a molding having a fixed portion that is fixed on an inner surface of a lower edge of a windshield glass, and a fitting portion that receives an engagement rib that protrudes downward from a location near an upper edge of a cowl louver, wherein the engagement rib and the fitting portion include slip-out prevention projections that prevent the engagement rib from slipping out. On both sides of the engagement rib are provided elastic lips and that are supported by the fitting portion, and these elastic lips extend in the extending direction of the engagement rib and press on the engagement rib at a side closer to a tip of the engagement rib than the slip-out prevention projections, these elastic lips press each other in opposite directions.

First claim

The invention claimed is:

1. A connecting structure for a windshield glass and a cowl louver, comprising:
a molding having a fixed portion that is fixed on an inner surface of a lower edge of the windshield glass, and a fitting portion that receives an engagement rib that protrudes downward from a location near an upper edge of the cowl louver and that extends along the upper edge, wherein
the engagement rib and the fitting portion include slip-out prevention projections that prevent the engagement rib from slipping out of the fitting portion by cooperation of the slip-out prevention projections,
the molding has a first elastic lip that is supported by the fitting portion on a windshield glass side with respect to the engagement rib, and a second elastic lip that is supported by the fitting portion on an opposite side of the first elastic lip with respect to the engagement rib,
the first and second elastic lips press on the engagement rib at a side closer to a tip of the engagement rib than the slip-out prevention projections, and the first and second elastic lips press each other in opposite directions, and
the cowl louver has a plurality of first auxiliary ribs that extend in a longitudinal direction of a vehicle on the windshield glass side with respect to the engagement rib.

2. The connecting structure for the windshield glass and the cowl louver according to claim 1 , wherein
a reference direction is a direction perpendicular to a protrusion direction and an extending direction of the engagement rib, the sum of lengths of the first and second elastic lips protruding from inner surfaces of the fitting portion in the reference direction, in a free state before the engagement rib is fit to the fitting portion, is greater than a value obtained by subtracting a thickness of the engagement rib in the reference direction from a distance between the inner surfaces of the fitting portion in the reference direction.

3. The connecting structure for the windshield glass and the cowl louver according to claim 2 , wherein
in a sectional view taken along a longitudinal direction of the vehicle, the cowl louver is relatively pivotable, with respect to the molding, about a pivoting point that is located at a part where the slip-out prevention projections of the engagement rib and the fitting portion are engaged with each other,
a reference point is a foot of a perpendicular drawn from the pivoting point to a centerline of the engagement rib, a first distance and a second distance are distances from the reference point to positions where the first and second elastic lips press on the engagement rib, the first distance and the second distance are expressed in terms of a distance in a protruding direction of the engagement rib,
pressing forces of the first and second elastic lips pressing on the engagement rib are represented by a first pressing force and a second pressing force, and
a ratio of the first pressing force to the second pressing force is greater than the ratio of the second distance to the first distance.

4. The connecting structure for the windshield glass and the cowl louver according to claim 2 , wherein
the slip-out prevention projections of the engagement rib and the fitting portion are provided on the windshield glass side with respect to the engagement rib.

5. The connecting structure for the windshield glass and the cowl louver according to claim 1 , wherein
a position where the first elastic lip presses on the engagement rib is on a side closer to the tip of the engagement rib than a position where the second elastic lip presses on the engagement rib.

6. The connecting structure for the windshield glass and the cowl louver according to claim 1 , wherein
the first and second elastic lips extend in a extending direction of the engagement rib.

7. The connecting structure for the windshield glass and the cowl louver according to claim 1 , wherein
the engagement rib does not protrude in a direction approaching the inner surface of the fitting portion on the side closer to the tip of the engagement rib than a position where the first elastic lip presses on the engagement rib, and
the engagement rib does not protrude in a direction approaching the inner surface of the fitting portion on the side closer to the tip of the engagement rib than a position where the second elastic lip press on the engagement rib.

8. The connecting structure for the windshield glass and the cowl louver according to claim 7 , wherein
a thickness of a main body of the engagement rib gradually decreases toward the tip of the engagement rib.

9. The connecting structure for the windshield glass and the cowl louver according to claim 1 , wherein
the first and second elastic lips are integrally connected to the fitting portion at respective root portions, and
at least one of the first and second elastic lips, in a free state before the engagement rib is fit to the fitting portion, is inclined downward.

10. The connecting structure for the windshield glass and the cowl louver according to claim 1 , wherein
the molding has an interposed portion that is interposed between the lower edge of the windshield glass and the upper edge of the cowl louver,
an opposing face of the interposed portion that opposes the cowl louver of the interposed portion is inclined toward the lower edge of the windshield glass as it approaches an outer end of the interposed portion,
the upper edge of the cowl louver has an opposing face of the cowl louver that opposes the opposing face of the interposed portion and that is inclined in the same direction as the opposing face of the interposed portion, and
the opposing face of the interposed portion and the opposing face of the cowl louver overlap each other as seen from the direction perpendicular to an outer face of the upper edge of the cowl louver.

11. The connecting structure for the windshield glass and the cowl louver according to claim 1 , wherein
a said slip-out prevention projection for the engagement rib is provided on one of the plurality of first auxiliary ribs.

12. The connecting structure for the windshield glass and the cowl louver according to claim 10 , wherein
the first auxiliary ribs have a pinched and pressured portion that is pinched and pressured between the opposing face of the interposed portion and the opposing face of the cowl louver.

13. The connecting structure for the windshield glass and the cowl louver according to claim 1 , wherein
the cowl louver has a plurality of second auxiliary ribs that extend in a longitudinal direction of the vehicle on the opposite side of the windshield glass with respect to the engagement rib, and
the fitting portion is engaged with the inner surface of the cowl louver and the second auxiliary ribs at a tip portion of the fitting portion on the opposite side of the fixed portion with respect to the engagement rib.

14. The connecting structure for the windshield glass and the cowl louver according to claim 13 , wherein
the engagement rib and a stopper integrally provided on the inner surface of the cowl louver are on opposite sides of the second auxiliary ribs, the stopper being at a location spaced from the second auxiliary ribs.

15. The connecting structure for the windshield glass and the cowl louver according to claim 10 , wherein
the interposed portion of the molding supports a cover at a tip portion of the interposed portion,
the cover protrudes from the tip portion of the interposed portion toward the upper edge of the cowl louver and extends along an entire width of the molding, and
the cover is in contact with an oute
