RECEPTACLE

PROBLEM TO BE SOLVED: To provide a receptacle capable of reliably preventing a plug blade from coming off an insertion part due to forgetting or the like of a pull-stop work. SOLUTION: The receptacle includes: a case 1; an insertion part 2 which is provided in the outer surface of the case 1 and consists of three blade insertion holes 2a-2c into which respective blades P1-P3 of the plug P are respectively inserted, and three blade receptacle parts 20 which are housed in the case 1 and to which respective blades P1-P3 are respectively contacted and connected; and a locking member which is housed in the case 1 and retains contact state of the blade P3 of one ground electrode and the blade receptacle part 20 in the insertion part 2. The locking member consists of a locking spring 3 having a pressure contact piece 30 which is elastically biased in a direction to pressure-contact the blade P3 to a rib 12a of the case 1, and the pressure contact piece 30 is slanted in a direction to narrow the distance between the pressure contact piece and the rib 12a along the insertion direction of the blade P3.
