Abstract

A shutter couples to an upper part of a cargo bed by left and right tracks mounted on left and right side walls of the cargo bed. A tailgate is mounted on a rear end of the cargo bed. A bed liner seal member is provided on rear ends of the left and right side walls. A touch member provided on a rear part of the shutter makes elastic contact with the bed liner seal member when the shutter is fully extended. A shutter seal member provided on the shutter makes elastic contact with the tailgate. A tailgate seal member provided on the tailgate makes elastic contact with the bed liner seal member. First and second seal beads on an upper surface are provided on an upper wall of a protrusion of the bed liner seal member. The touch member touches the first and second seal beads.

First claim

We claim:

1 . A sealing structure for a truck cargo bed with a shutter, the sealing structure comprising:
a cargo bed for a truck; the shutter which couples to an upper part of the cargo bed by a left track and a right track, the shutter extending in parallel with the cargo bed, the shutter moving between at least two positions in a front and rear direction of an automobile body to open and close an opening on the upper part of the cargo bed, a left side wall vertically mounted on a left end of the cargo bed; a right side wall vertically mounted on a right end of the cargo bed; the left track mounted on a top edge of the left side wall; the right track mounted on a top edge of the right side wall; a tailgate mounted on a rear end of the cargo bed, the tailgate being pivotal in a front and rear direction of the automobile body with a lower end part of the tailgate as a pivotal axis, the tailgate in a closed position and the left and right side walls surrounding the cargo bed; a bed liner seal member provided on rear ends of the left and right side walls; a touch member provided on a left side end and a right side end of a rear part of the shutter, the touch member configured to make elastic contact with the bed liner seal member when the shutter is fully extended, the touch member configured to touch first and second seal beads on an upper surface from an upper side; a shutter seal member provided on a rear end of the shutter, the shutter seal member configured to make elastic contact with the tailgate when the tailgate is in the closed position; a protrusion which forms a part of the bed liner seal member; and the first and second seal beads provided on an upper wall of the protrusion, the first and second seal beads extending in a right and left direction of the automobile body.

2 . The sealing structure as claimed in claim 1 , further comprising a tailgate seal member provided on an upper part of a front surface of the tailgate, the tailgate seal member configured to make elastic contact with the bed liner seal member when the tailgate is in the closed position.

3 . The sealing structure as claimed in claim 1 , further comprising third and fourth seal beads on a side surface, the third and fourth seal beads being provided on a side wall of the protrusion of the bed liner seal member, the third and fourth seal beads extending in an upper and lower direction of the automobile body, the side wall being close to an inner side of the cargo bed, the touch member configured to touch the third and fourth seal beads from a lateral side.

4 . The sealing structure as claimed in claim 3 , wherein the first and second seal beads on the upper surface are continuous with the third and fourth seal beads on the side surface, the first and second seal beads being parallel with each other and provided on the upper wall of the protrusion of the bed liner seal member, the third and fourth seal beads being parallel with each other and provided on the side wall of the protrusion of the bed liner seal member.

5 . The sealing structure as claimed in claim 3 , further comprising:
a first gutter formed beneath the protrusion of the bed liner seal member, the first gutter being closer to a front part of the automobile body than the protrusion, the first gutter extending in the right and left direction of the automobile body; and a second gutter formed beneath the third and fourth seal beads on the side surface, the second gutter being closer to an interior of an automobile than the side wall of the protrusion of the bed liner seal member, the second gutter extending in the front and rear direction of the automobile body, the second gutter being continuous with the first gutter.

6 . The sealing structure as claimed in claim 5 , further comprising a hole closer to a rear part of the automobile body than the second gutter, the hole configured to drain water guided into the first and second gutters toward an exterior of the automobile.

7 . The sealing structure as claimed in claim 5 , wherein the touch member includes:
an upper wall; a side wall which extends downward from a part of the upper wall closest to the interior of the automobile and in the front and rear direction of the automobile body; and an inner wall which extends downward from a part of the upper wall closest to the front part of the automobile body and in the right and left direction of the automobile body, wherein when the shutter is fully extended, a lower surface of the upper wall of the touch member touches the first and second seal beads on the upper surface, an outer side surface of the side wall touches the third and fourth seal beads on the side surface, a lower surface of the inner wall makes elastic contact with a first wall which forms a part of the first gutter, and a lower surface of the side wall makes elastic contact with a second wall which forms a part of the second gutter.

8 . The sealing structure as claimed in claim 7 , wherein a lower end of the inner wall of the touch member is folded toward the front part of the automobile body such that the inner wall has an L-shaped cross section.
