Abstract
There is disclosed an optical connector for use in an endoscope. The optical connector includes a connector body for fixedly receiving one end portion of a light guide, and a retainer receiving an optical element. The retainer is threaded on the connector body to such an extent that an abutment surface of the retainer is abutted against a stopper surface of the connector body. An annular flange is formed on an inner periphery of the retainer adjacent to a distal open end of the retainer. The optical element and an annular elastic member are disposed between the flange of the retainer and a distal end surface of the connector body. The elastic member urges the optical element against the flange, thereby keeping the optical element away a predetermined distance from the one end of the light guide.
