具合もある。(Problems to be solved by the invention) In the above fixing structure, the bumper arm (A) is prevented from hanging down the upper wall (C) of the bumper (B).
However, it is difficult to reliably prevent the upper wall (C) of the bumper (B) from rising above the bumper arm (A), and it is difficult to compare the bumper arm (A) with the bumper arm (A). Since the resin bumper (B) having low static rigidity is only bolted, the mounting strength of the bumper (B) to the body is weak and there is also a problem that the construction is likely to be misaligned.

A fixing structure for fixing a resin bumper provided with a bumper bracket attached to a body, and a holding portion having a substantially U-shaped cross section that elastically holds both upper and lower surfaces of an edge portion of the upper wall,
Reinforcement having a reinforcing frame portion along the fixed wall is disposed in substantially the entire width along the edge portion of the upper wall of the bumper, and the edge portion of the upper wall is held by the holding portion. On the other hand, the bumper bracket is provided with an upper fixing portion and a lower fixing portion that are opposed to each other near the upper wall of the fixing wall, and the upper fixing portion is provided with the fixing wall near the upper wall of the bumper. The fixing wall is bolted together with the reinforcing frame portion, while the fixing wall is bolted to the lower fixing portion.
