2. Description of the Related Art Generally, in vehicles such as automobiles, side doors, bonnets, and trunk lids are provided to secure dustproof and waterproof properties in a vehicle interior, an engine room, and a trunk, and to ensure soundproofness in the vehicle interior. And an opening forming member forming a vehicle body opening for these lid members are sealed by a seal member interposed in a loop between them. As the sealing member, a member formed in a closed loop shape in advance (USP 4760)
No. 636) or a strip having both ends (see JP-A-2-136381). By the way, when the strip-shaped seal member is used, a seal member cut in advance to a length substantially corresponding to the outer periphery of the opening is attached to one of the lid member and the opening forming member. Since it is difficult to attach the expandable and contractable seal member without excess or shortage, the length of the seal member is set to be slightly shorter so that both ends of the seal member do not overlap.

[0003]

The above-mentioned closed loop-shaped sealing member has excellent sealing properties, but its manufacturing cost is high, and the strip-shaped sealing member can be manufactured relatively inexpensively. Due to the mounting of the seal member in a loop, there is a problem that a portion that cannot be sealed is generated between both ends of the seal member and the sealing performance is reduced.

An object of the present invention is to provide a mounting structure of a vehicle sealing member which can secure sufficient sealing performance with a strip-shaped sealing member which can be manufactured at a low cost.

[0005]

According to a first aspect of the present invention, there is provided a vehicle sealing member mounting structure, wherein a substantially loop-shaped sealing member is provided between an opening forming member forming an opening of a vehicle and a lid member mounted on the opening. In the mounting structure of the vehicle sealing member to be sealed with, in one of the opening forming member and the lid member,

The other of the object members is provided with a second seal member having a bridging portion for sealing between both ends of the first seal member and wrap portions each extending from both ends thereof and wrapping with the first seal member. The first seal member and the second seal member are in contact with each other.
It is configured to elastically deform in the orthogonal direction.

Most of the gap between the opening forming member and the lid member is sealed by the first sealing member, and the opening forming member and the lid between both ends of the first sealing member are bridged by the second sealing member. The gap between the members is sealed. In the wrap portion of the second seal member, one of the first seal members
The strip seal portion is pressed into contact with the second seal member so as to be inserted between the two seal portions. Thus, the gap between the opening forming member and the lid member can be reliably sealed by the strip-shaped first seal member and the second seal member which can be manufactured at a low cost, similarly to the closed loop seal member. I can do it.

[0008] Then, the first seal member and the second sealing member
Since There are configured to elastically deform the direction perpendicular to the contact surface of both or hindered the closing operation of Futamono member wrapped portions of both seal member taut, sealability in the portion other than the lap portion Can be prevented from decreasing.

[0009]

As described in the above section, the following effects can be obtained. According to the mounting structure for a vehicle seal member according to claim 1, one of the opening forming member and the lid member is provided.
A first sealing member having a strip shape is provided in a substantially loop shape,
With the ends facing each other with a predetermined space,
A second seal member is provided on the other of the opening forming member and the lid member.
In the state where the opening is closed by the lid member, the second
In the wrap portion of the seal member, one of the first seal member
Of the second seal member is inserted between the two seal portions of the second seal member.
Since the pressure contact state forme, it is possible to reliably seal the gap between the opening forming member and the Futamono member between both ends of the first seal member with a second sealing member of a simple structure
In addition, the gap between the opening forming member and the lid member can be reliably sealed in the same manner as when the closed loop-shaped seal member is employed, while employing the strip-shaped first seal member which can be manufactured at low cost. .

[0010] The first sealing member and the second seal member is configured to elastically deform the direction perpendicular to the contact surface of both the first
One seal portion of the seal member is the same as the two seal portions of the second seal member.
Since it is pressed into contact between the seal portions, it is possible to prevent the wrap portions of the two seal members from stretching and hindering the closing operation of the lid member, and to prevent the sealing performance of portions other than the wrap portion from deteriorating.
