なって、外観上の統一が図れる。Here, in the retaining socket of the present invention, as shown in FIG. 4 (a), the positions of the blade insertion hole 15 and the blade receiving portion of the internal blade receiving spring 1 are determined by the plug blade insertion position. At this position, the plug blade of the plug is engaged with the blade insertion hole 15 and the protrusion 10A is engaged with the hole of the plug blade of the plug. When the plug 21 is rotated clockwise by 30 degrees from the inserted state and the plug blade is moved in the blade insertion hole 15, the plug 21 is moved in the width direction of the cover 14 as shown in FIG. The projection 10B engages with the hole of the plug blade at the position where the line X and the center line in the width direction of the plug 21 coincide with each other, so that the plug 21 can be prevented from coming off. Position is the same as the plug connection state in a normal outlet, and the appearance can be unified.
