JP 2006-15905 A

  In this vehicle bumper mounting structure, the upper protruding portion of the bumper spacer is locked to the lower plate portion, and the side protruding portion of the bumper spacer is locked to the side plate portion. The surface is locked.

Therefore, it is possible to attach the bumper spacer to the attachment position of the front end portion of the fender panel with high accuracy.
By engaging the bumper face with the bumper spacer, the bumper face can be accurately attached to the fender panel.

Here, in order to lock the upper protruding portion to the lower plate portion, it is necessary to provide a locking hole for locking the upper protruding portion in the lower plate portion.
For this reason, it is necessary to provide a lower plate portion so as to face the upper protruding portion. The lower plate portion is formed by being bent inside the vehicle body at the front end portion of the fender panel.

In order to bend the lower plate portion, it is preferable to form the front end portion of the fender panel relatively flat.
For this reason, there is a restriction on the shape of the fender panel, which hinders increasing the degree of freedom in design.

  It is an object of the present invention to provide a vehicle bumper mounting structure that can attach a bumper face to a fender panel with high accuracy and can further increase the degree of design freedom.

According to the first aspect of the present invention, the fender side wall is bent toward the vehicle body inside at the front end of the fender panel, the stepped portion is bent away from the fender panel at the end of the fender side wall, and the bumper spacer is placed on the stepped portion. Then, a bumper face is placed on the bumper spacer, and a bumper side wall bent at the end of the bumper face is disposed between the bumper spacer and the fender side wall, and a back surface of the bumper side wall is disposed on the bumper spacer. In the vehicle bumper mounting structure in which the surface of the bumper side wall faces the surface of the fender side wall, the locking claw provided on the bumper spacer and capable of locking to the locking hole of the bumper side wall from the back side, provided to the bumper spacer, the outer end of the fender side wall of the fender side walls The prevention hook falling preventing collapse of the bumper spacer by contacting to the back wraps around the surface, characterized by comprising a.

The invention according to claim 2 is characterized in that the bumper spacer is provided with a pressing piece capable of pressing the surface of the bumper side wall.
In the invention according to claim 3, the outer end portion is provided on the inner side in the vehicle width direction with respect to the peripheral portion of the fender panel, and the end attachment piece of the wheel arch molding attached to the peripheral portion of the fender panel, The wheel arch molding is attached to an end attachment piece of a wheel arch molding attached to a peripheral portion of the bumper face at the outer side in the vehicle width direction.

In the invention according to claim 1, the bumper spacer is provided with the hook for preventing the collapse. The bumper spacer can be prevented from falling in a direction away from the fender side wall by contacting the fall prevention hook with the back surface of the fender side wall.
Therefore, it is possible to attach the bumper spacer to the front end portion of the fender panel with high accuracy.
There is an advantage that the bumper face can be attached to the fender panel with high accuracy by locking the locking hole of the bumper side wall to the locking claw of the bumper spacer.

Further, the fall prevention hook was formed so as to be in contact with the back surface of the fender side wall from the outer end portion of the fender side wall . Therefore, it is not necessary to extend the fender side wall to the base of the hook for preventing the collapse, and the fender side wall extending along the front end portion of the fender panel can be shortened.
There is an advantage that the range of the fender panel which is restricted by the fender side wall can be reduced, and the degree of freedom in design can be increased.

In the invention according to claim 2, the bumper spacer includes the pressing piece. The surface of the bumper side wall is pressed with this pressing piece.
Therefore, both surfaces (front surface and back surface) of the bumper side wall can be held between the pressing piece and the locking claw, and the bumper side wall can be more securely attached to the bumper spacer.
Thereby, there exists an advantage that integration of a fender panel and a bumper face can further be improved.
In the invention which concerns on Claim 3, the edge part attachment piece of the wheel arch molding attached to the fender panel can be attached to a bumper face by providing an outer side edge part in a vehicle width direction inner side with respect to the peripheral part of a fender panel. There is an advantage that it can be coupled to the end mounting piece of the wheel arch molding on the outer side in the vehicle width direction of the outer end.
