The cylinder 130 may be a hydraulic cylinder or a pneumatic cylinder.

Accordingly, when the cylinder 130 is a hydraulic cylinder, the cylinder drive medium is compressed oil. When the cylinder 130 is a pneumatic cylinder, the cylinder drive medium is compressed air. When such a cylinder drive medium is operated by the manual control unit 140, And the piston rod 132 is moved to be moved forward or vice versa. The operation of the cylinder 130 is known in the art, so detailed drawings and description will be omitted.

Since the cylinder drive unit 5 is already known in the vehicle, detailed descriptions and explanations thereof will be omitted, and the manual control unit 140 is also a known component, so detailed drawings and explanations will be omitted.

Preferably, the manual control unit 140 is installed in the driver's seat.

2, so that the reflection plate 7 of the rear bumper 4 can be easily distinguished from other vehicles traveling in the rear direction, the fixing portion 31 and the bumper mounting portion 32 are in a straight line.

In this state, the rear bumper 4 is not shaken because the bumper mounting portion 32 is supported in a state in which the piston rod 132 of the cylinder 130 is moved forward.
