To explain the outline, a pair of protrusions 9 are formed on the first locking member 6, and the protrusions 9 are fitted into holes formed in the side wall 1a of the vehicle body 1, and a tapping screw is inserted into the protrusions 9. By screwing in the first
The locking member 6 is fixed to the side wall 1a of the vehicle body 1.
Further, the first locking member 6 is formed with a pair of engagement grooves 10 that protrude in a direction opposite to the protrusion 9, and the engagement grooves 10 have a hook-shaped cross section that constitutes a groove side portion. The second locking member 8 has a pair of claws with an arrow-shaped cross section, and is made up of a pair of engaging pieces 11 with spring properties and an abutment part 12 with spring properties that constitutes the bottom of the groove. The portion 13 is adapted to slidably engage with the engagement groove portion 10.

The second locking member 6 locked in this way
As shown in FIG.
is in contact with the abutment part 12 of the engagement groove part 10,
As a result, the position of the bumper 2 in the width direction of the vehicle body 1 is determined, but the position in the longitudinal direction is determined by the second locking member 8.
is designed to slide with respect to the first locking member 6, so it is uncertain; therefore, the distance between the bumper mounting surface 1b of the vehicle body 1 and the front end surface 2a of the bumper 2 shown in FIG. There is an installation problem in that the so-called parting width dimension a becomes uncertain and cannot be managed. Also, when attaching the bumper 2 to the vehicle body 1, the first
There is a problem in that one side of the second locking member 8 comes into contact with one side of the second locking member 6, and the claw portion 13 cannot smoothly engage with the engagement groove 10.
