PROBLEM TO BE SOLVED: To securely fix an insulation sealing member by holding the insulation sealing member at an insulation seal attachment part by a stopper. SOLUTION: A base face part of an insulation sealing member 60, an inner circumference face of the sealing member 60, and an end face of a cylindrical part 6 respectively are abutted with a bottom face of a socket side fitting part 4, an outer circumference face of the cylindrical part 6, and an abutting face 67 of a head part 66 of the sealing member 60, a stopper 70 inserts a guide part 75 of a pair of leg parts thereof into a pair of guides 11 of the stopper attachment part and is pushed, and a lower face of a receptacle part 72 abuts with an upper end of the guide 11. In this state a lock protrusion 76 of the pair of leg parts is removably locked with a lock part of a stopper attachment part, and a seal holding part 71 depresses a flat end face 65 of the head part 66 of the sealing member 60 from above. Thus, the head part 66 of the insulation sealing member 60 is pinched by an end face of the cylindrical part 6 and the seal holding part 71 of the stopper 70 so as to ensure attachment of the insulation sealing member 60 to the seal attachment part 7. |
