By locking the scissors fixing bracket below the edge of the opening, it is possible to firmly hold the body so that it does not move upward even if upward force is applied to the body when pulling out the plug from the outlet unit. It is possible to increase the mounting strength of the body.

Further, the cover is provided on the opening surface of the body disposed in the floor surface so that the opening surface of the body is substantially flush with the floor surface, and an opening for inserting the plug when the plug is attached is provided in the cover. Since the door body for opening and closing the opening is provided in the cover, and the concave cord stopper for pressing and fixing the cord connected to the plug on the upper surface of the cover is formed integrally with the door body, By holding the cord drawn out from the body to the floor with the cord stopper provided on the upper surface of the cover, even if you hook your foot on the cord, no force is applied directly to the outlet unit or plug. It is possible to prevent damage to the insulator and disconnection of the plug from the outlet unit.

Further, by providing the cord stopper integrally with the door body, it is not necessary to provide the cover with a cord stopper formed separately from the door body, and the cord body can be pressed using the door body that closes the opening of the cover. It can be attached and fixed, the configuration of the parts is simple, and the labor of attachment can be reduced.

In addition, since the recess is formed in the body at the portion where the cable electrically connected to the outlet unit is inserted, the portion where the cable is inserted can be confirmed at a glance even from the outside of the body. Can be performed easily and efficiently.
