This eliminates the need for tedious work and eliminates the need for nuts.

f Embodiment An embodiment in which the present invention is applied to a bumper extension of a front bumper will be described below with reference to FIGS. 1 to 4. FIG. 1 shows a front perspective view of an automobile, in which 1 is a front bumper and 2 is a bumper extension. As shown in FIGS. 2 to 4, the lower edge of the front bumper 1 is bent rearward to form an L-shaped flange 1a.

A plurality of U-shaped insertion holes 10 are formed on the edge of the flange portion 1a at approximately equal intervals along the longitudinal direction of the flange portion 1a. Each of these insertion holes 10
The open end is closed by a plate-like member 11, and this plate-like member 11 prevents a screw 18, which will be described later, from coming off. Note that plate-shaped member 1
As shown in FIGS. 2 and 4, the lower end of the flange portion 1 forms a convex fitting portion 11a that projects slightly below the lower surface of the flange portion 1a.

On the other hand, the bumper extension 2 is mainly composed of a mounting plate part 2a overlapping the lower surface of the flange part 1a, and an extension plate part 2b extending downward from the front end of the mounting plate part 2a. Mounting plate part 2
As shown in FIGS. 2 and 3, a predetermined number of engagement grooves 12 having a U-shaped cross section and opening toward the front are formed at the rear end of the flange portion 1a.
It is adapted to engage the edge of the Mounting plate part 2a
As shown in FIGS. 2 and 4, a plurality of U-shaped insertion holes 13 are formed approximately in the middle of the hole. A fitted portion 14 is formed. A bumper 1 is provided on the mating portion 14 as shown in FIG.
The fitting portion 11a on the side can be fitted, and in this fitted state, each insertion hole 10 of the flange portion 1a and each insertion hole 13 of the mounting plate portion 2a are configured to communicate with each other. .

At the rear end of the mounting plate portion 2a between the plurality of engagement grooves 12, a fitted portion 1
A rotary plate 15 is connected so as to straddle 4. This rotating plate 15 is connected to the mounting plate part 2a via a pair of left and right hinge parts 16, and the bumper extension 2 is connected to the bumper 1 as shown in FIG.
By rotating it forward (to the left in FIG. 4) while it is attached to the flange portion 1a, it can be overlapped with the upper surface of the flange portion 1a. Rotating plate 1
As shown in FIGS. 2 and 4, a cylindrical boss portion 17 is integrally formed on one side of the portion 5 at a substantially right angle. This boss portion 17 is designed such that its hole 19 communicates with each insertion hole 10, 13 of the flange portion 1a and the mounting plate portion 2a when the rotating plate 15 is superimposed on the upper surface of the flange portion 1a as shown in FIG. It's getting old.

The bumper extension 2 for an automobile is constructed as described above. To install the bumper extension 2, first raise the rotating plate 15 as shown in FIG. 1
2 is engaged with the edge of the flange portion 1a of the bumper 1. Next, by pulling the lower end of the bumper extension 2 forward as shown by the arrow in FIG. 3, the mounting plate 2a is pressed against the flange 1a, and the fourth
As shown in the figure, the fitting portion 11a of the plate member 11 is fitted into the fitted portion 14 of the mounting plate portion 2a. As a result, the bumper extension 2 is temporarily fixed, and there is no need to support the bumper extension 2.

Next, the rotating plate 15 is tilted forward as shown by the arrow in FIG. screw into the hole 19 of the part 17, and connect the flange part 1a to the mounting plate part 2a and the rotating plate 15.
The installation of the bumper extension 2 is completed by sandwiching the bumper extension 2 between the two.
