Abstract
There is provided a joining structure of a resin member for a vehicle body and a stud bolt that can more strongly fix a stud bolt to a resin member for a vehicle body by an ultraviolet curable adhesive. Convex portions are provided at a portion, which structures a flange-adjacent portion, of a mounting surface portion of a resin member for mounting. Therefore, a surface area of adhesion with adhesive at a place, which is covered by a flange portion as seen in a plan view, of the mounting surface portion can be made to be large. As a result, adhesive force of a portion, which is cured by diffused ultraviolet rays, of the adhesive A that is covered by the flange portion as seen in a plan view can be made to be large.
Claims13
A joining structure of a resin member for a vehicle body and a stud bolt, comprising:
- a resin member for a vehicle body that structures a portion of a vehicle body;
- a stud bolt that is made of metal and is structured to include a shaft portion at which a male screw portion is formed, and a flange portion that is plate-shaped and is provided integrally with the shaft portion at one end portion of the shaft portion;
- and
- a resin member for mounting that includes:
- a flange-adjacent portion, which is covered by the flange portion and is adjacent to a surface of the flange portion which surface is at a side opposite the shaft portion;
- and
- an extending portion, which is continuous with the flange-adjacent portion and extends-out from a peripheral edge portion of the flange portion as seen in a plan view, the resin member being formed of a resin through which ultraviolet rays can be transmitted and is provided integrally with the flange portion, and a mounting surface portion, which is provided at a side opposite the stud bolt, of the resin member for mounting being joined via an ultraviolet curable adhesive to the resin member fix a vehicle body, and at least one of concave portions and convex portions being provided at a portion, which structures the flange-adjacent portion, of the mounting surface portion.
A joining structure of a resin member for a vehicle body and a stud bolt of claim wherein at least one of flange portion side concave portions and flange portion side convex portions are formed at a joining surface portion, which is at a side of the resin member for mounting, of the flange portion.
A joining structure of a resin member for a vehicle body and a stud bolt, comprising:
- a resin member for a vehicle body that structures a portion of a vehicle body;
- a stud bolt that is made of metal and is structured to include a shaft portion at which a male screw portion is formed, and a flange portion that is plate-shaped and is provided integrally with the shaft portion at one end portion of the shaft portion, and a plurality of through portions are formed in the flange portion;
- and
- a resin member for mounting that includes:
- a flange-adjacent portion, which is covered by the flange portion and is adjacent to a surface of the flange portion which surface is at a side opposite the shaft portion;
- and
- an extending portion, which is continuous with the flange-adjacent portion and extends-out from a peripheral edge portion of the flange portion as seen in a plan view, the resin member being formed of a resin through which ultraviolet rays can be transmitted and is provided integrally with the flange portion, and a mounting surface portion which is provided at a side opposite the stud bolt, of the resin member for mourning being joined via an ultraviolet curable adhesive to the resin member for a vehicle body.
