It is possible to prevent deformation or breakage.

Here, the guide rail 32a is manufactured by an injection process so that the guide rail 32a is integrally formed when the housing 30 in which the moving hole 32 is formed is formed in a separate process of processing the guide rail 32a. This can be omitted.

When the opening operation as described above is completed, since the lens of the camera 10 installed in the guide block 50 is exposed to the outside of the vehicle, the rear state of the vehicle is output as an image through a monitor installed in the driver's seat.

A pair of guide rails 32a are formed on both inner walls of both sides of the moving hole 32, and a plurality of guide protrusions 32a are continuously formed on both side surfaces of the guide block 50. .

Therefore, a part of the guide protrusions 52 formed on the side of the guide block 50 is slid along the guide rails 32a formed on the upper portion of the moving hole 32, and the rest of the guide protrusions 52 are movable hole portions ( It slides along the guide rail (32a) formed in the lower portion of the 32.

In particular, since the pair of guide protrusions 52 are in contact with the guide rail 32a formed at the lower portion of the movable hole 32 at the same time, the guide block 50 sliding along the movable hole 32 is forward or backward or left and right directions. It is possible to prevent the flow to.

As described above, it is possible to suppress the flow when the guide block 50 is moved by the guide rail 32a and the guide protrusion 52, so that the camera 10 malfunctions or is damaged by the flow of the guide block 50. Can be prevented.

When the reverse driving of the vehicle is finished, the guide block 50 is inserted into the moving hole 32 by the operation of the driving unit 90, so that the outer surface is restrained by the restoring force of the first elastic member 82 and the second elastic member 84. The panel 75 and the inner panel 71 are rotated about the rotation shaft 38 to close the moving hole 32.
