Abstract

A ceiling portion of a service plug cover that is made of resin is convex toward a vehicle vertical direction lower side (floor panel side), and a groove-shaped concave portion is formed in a top surface. Further, the concave portion of the top surface of the ceiling portion is groove-shaped, and both end portions thereof in a groove direction (vehicle longitudinal direction) are open.

First claim

The invention claimed is:

1. A service hole cover comprising:
a cover main body that is removably provided at a panel of a vehicle so as to cover a service hole formed in the panel, the cover main body being shaped as a box having a lower side that is open; and
a ceiling portion that forms an upper portion of the cover main body, the ceiling portion of the cover main body being convex in a direction projecting away from the panel of the vehicle, the ceiling portion including a concave portion projecting towards the panel of the vehicle, the concave portion being formed in a center portion of a top surface of the ceiling portion, the concave portion being groove-shaped and having end portions that are open in a longitudinal direction of the service hole cover.

2. The service hole cover of claim 1 , wherein a bottom portion of the concave portion is inclined downward while heading from the center portion in a groove direction toward both end portions, or the bottom portion of the concave portion is inclined downward while heading from one end portion in the groove direction, toward another end portion.

3. The service hole cover of claim 1 , further comprising first ribs that extend along a side wall height direction that are formed at outer surfaces of side walls of the cover main body.

4. A unit mounting structure for a vehicle comprising:
a vehicle floor in which a service hole is formed;
an operation portion that is provided at a unit for the vehicle disposed at a lower side in a vehicle vertical direction of the vehicle floor, the operation portion projecting-out towards the service hole;
the service hole cover of claim 1 , removably provided at a top surface of the vehicle floor;
a duct that is disposed at a vehicle vertical direction upper side of the service hole cover; and
a buffering member that is provided at a duct side, the buffering member being nipped between the duct and the service hole cover.

5. The service hole cover of claim 1 , further comprising:
second ribs that extend along an intersecting direction that intersects a groove direction of the concave portion, the second ribs being formed at the top surface of the ceiling portion of the cover main body; and
drainage portions that pass through in the groove direction, the drainage portions being formed at regions of the second ribs that are formed at the concave portion.

6. The service hole cover of claim 5 , wherein the second ribs are formed such that upper end portions of the second ribs do not extend past an upper end portion of the top surface of the ceiling portion.

7. The service hole cover of claim 1 , further comprising third ribs that extend along a side wall height direction, the third ribs being formed at inner surfaces of side walls of the cover main body.

8. The service hole cover of claim 1 , further comprising fourth ribs that extend along an intersecting direction that intersects a groove direction of the concave portion, the fourth ribs being formed at a bottom surface of the ceiling portion of the cover main body.

9. A unit mounting structure for a vehicle, the unit mounting structure comprising:
a vehicle floor in which a service hole is formed;
an operation portion that is provided at a unit for the vehicle disposed at a lower side in a vehicle vertical direction of the vehicle floor, the operation portion projecting-out towards the service hole; and
vice hole cover of claim 1 , removably provided at a top surface of the vehicle floor.
