The present invention is provided with a base body that pivotally supports a reception member and that is screwed into an engraved top surface formed above a door frame, and an ornamental cover that blocks an opening part of the engraved section. The dimensions of the base body in the left-right direction of the door frame are smaller than the dimensions of the engraved section. A screw passing section has a long oblong hole shape in the left-right direction of the door frame, and the base body is provided with a latch depression for a latch claw disposed on the ornamental cover so as to be long in the left-right direction of the door frame.
