Optical connector

An optical connector attached to an optical fiber including a glass fiber and a resin coating covering the glass fiber, the optical connector comprising:

• a ferrule assembly including a ferrule fixed to a distal end portion of the glass fiber exposed from the resin coating in the optical fiber and a holding portion to which a rear end portion of the ferrule is fixed and provided with a flange;
• a housing having an internal space in which at least the holding portion of the ferrule assembly is stored, and a positioning portion for restricting movement of the holding portion in the internal space;
• an elastic member configured to bias the flange toward the positioning portion;
• and
• an urging force transmission member having a first surface abutting against the flange and a second surface positioned on an opposite side of the first surface and abutting against the elastic member, the urging force transmission member transmitting an urging force by the elastic member to the flange, wherein
• the urging force transmission member has a through hole that allows the holding portion to pass therethrough and is arranged between the flange and the elastic member in a state of allowing a part of the holding portion to pass through and being rotatable about a central axis of the holding portion.
