For example, the support portion 27 may be provided at the upper end portion of the projecting portion 23, and the door body 31 may be rotated about the shaft 32 attached to the support portion 27. That is, one end of the door body 31 is the upper end portion, and the other end of the door body 31 is the lower end portion.

In the above-described embodiment, as shown in FIG. 3, the door body 31 is provided on the front surface 23A of the protruding portion 23, but the door body 31 may be provided on at least one of the two side surfaces of the protruding portion 23 in the left-right direction Y.

In the above embodiment, although the front surface of the socket main body 20 is fixed to the wall body 5 of the charging stand 1 as shown in FIG. 1, the mounting form of the socket main body 20 with respect to the wall body 5 is not limited to this. For example, the rear side or the side surface of the socket main body 20 may be fixed to the wall body 5. In this case, the appearance of the socket 10 can be improved by attaching the cover 60 shown in FIG. 8 to the socket body 20.

In the above embodiment, although the socket 10 is incorporated in the charging stand 1 as shown in FIG. 1, the application of the socket 10 is not limited thereto. For example, the socket 10 may be mounted on the outer wall surface of a house such as a house.

Alternatively, the socket 10 may be incorporated in a control panel mounted on the wall surface. Further, the configuration is such that the socket 1 is provided on the socket having the socket body and the door body, and the insertion opening formed on the front side of the socket body is provided on the front surface and is provided with the protruding portion after the door body is attached. As long as the device is mounted by attaching the front side of the socket 10 to a panel or the like, the same effect as the effect (1) of the above embodiment can be obtained.

In the above-described embodiment, the charging device is embodied as a charging stand 1 that is connected to an electric vehicle via a cable to charge a battery of the electric vehicle.
