ンパの形状保持性の点で問題がある。(Prior Art) Conventionally, it is known that a shock absorber is arranged between a rigid reinforcement on the side of a vehicle such as an automobile and a flexible vehicle bumper made of synthetic resin (for example, (See Publication No. 60-256). However, in conventional vehicle bumper installation, the shock absorber is usually made of foamed synthetic resin, so it expands and contracts due to heat, changes in the outside air environment, etc. Due to errors during installation, gaps may easily occur between the bumper and the bumper.
For this reason, the bumper is likely to be dented, which poses a problem in terms of shape retention of the bumper.

である。(Structure of the Invention) In the assembly of a vehicle bumper made of synthetic resin, the present invention provides a shock absorber and an expansion/contraction structure between the reinforcement provided on the body and the vehicle bumper made of synthetic resin. A flexible and hollow box-like member is assembled, and then foamed resin is injected into the inside of the box-like member using an injection means to stretch the box-like member, and the shock absorber and a synthetic resin vehicle are assembled. It is characterized by eliminating the gap between the bumper and the bumper.

を無くし、形状を保持するものである。 That is, when foamed resin is injected into the inside of a box-shaped member that can be expanded and contracted using an injection means, the box-shaped member expands due to the volume expansion of the foamed resin inside the box-shaped member, and the shock absorber is used for vehicles. Press it against the bumper,
This eliminates the gap between the shock absorber and the vehicle bumper and maintains the shape.

を注入する。 The vehicle bumper installation method of this embodiment consists of a reinforcement 2 provided on the body 1 in the vehicle width direction (direction perpendicular to the plane of the drawing) and a synthetic resin vehicle reinforcement provided in front of the body 1. A shock absorber 4 (for example, polyethylene foam, urethane foam) is installed between the vehicle bumper 3 and the bumper 3.
In addition, a hollow box-shaped member 5 which can be expanded and contracted in the front-rear direction of the body 1 is attached to the reinforcement 2 side. Next, the inside of this box-shaped member 5 and the foamed resin injection means 6 (for example, a low-pressure foaming machine)
In the state in which the

押し付けによつて無くなる。 Due to the expansion of the foamed resin 7 injected into the inside of the box-shaped member 5 through this injection operation, the box-shaped member 5 is extended back and forth between the reinforcement 2 and the shock absorber 4 . At this time, while the reinforcement 2 is a rigid body, the shock absorber 4 and the vehicle bumper 3 are flexible. Therefore, before the injection, the shock absorber 4 and the vehicle bumper 3 are Even if there is a gap S between them, this gap S will be eliminated by the expansion of the box-shaped member 5 and the mutual pressing.

A lid body 5b fitted therein, a box body 5a and a reinforcement 2 fixedly attached to the lid body 5b.
It consists of a guide rod 5c that loosely fits and passes through the box-shaped member 5 to guide the positioning of the box-shaped member 5 and its movement in the front-rear direction. The injection port 5d of the box-shaped member 5 and the discharge port 6a of the injection means 6 are connected by a tube 8, so that the foamed resin 7 from the injection means 6 is injected into the box-shaped member 5. .

他、作業性が良好となるという利点がある。(Effects of the Invention) With the above configuration, the present invention injects foamed resin into the inside of the hollow box-shaped member, and uses the expansion force of the foamed resin to press the shock absorber against the vehicle bumper.
Since the gap between them is eliminated, it is possible to eliminate the gap caused by differences in expansion due to temperature and assembly errors of the shock absorber. Furthermore, there are advantages in that the shape retention and surface rigidity of the vehicle bumper are improved, and workability is improved.
