Abstract: In an optical connector of the invention, the rotation in a conventional angle polish connector can be prevented, while external force acting on the connector can be prevented from affecting a ferrule. The optical connector includes a ferrule 15, which has an angle-polished front portion and is accommodated in a housing 19 in a state where pressing force is applied in a coupling-forward direction by an elastic means so as to enable the ferrule 15 to move in the axial direction. A key groove 21 and a key 23 which are provided between the housing 19 and the ferrule 15 are engaged so as to make their relative movement possible in the movement direction. The clearance C between the groove width W of the key groove 21 and the key 23 increases along the direction in which the ferrule 15 retreats.
