A sloped cam surface (17) and a cam follower (30) are provided on the facing surfaces of a plug (1) and a socket (2) so as to face each other, the sloped cam surface (17) and the cam follower (30) being configured so that, when axially fitted to each other, the plug (1) and the socket (2) are brought into sliding contact with each other and rotated relative to each other, thereby being positioned relative to each other in the direction of rotation about the center axis. A pin insertion hole (18) is provided at the center of one of the facing surfaces of the plug (1) and the socket (2), and a center pin (31) adapted to be fitted in the insertion hole (18) before the sloped cam surface (17) and the cam follower (30) are in contact with each other is provided at the center of the other so as to protrude therefrom. |
