PURPOSE:To make the connector watertight and protect the incident end face for lighting light from heat hazards by hermetically sealing the opening for incident light provided at the incident end for lighting light of an optical fiber bundle by a cover glass. CONSTITUTION:An optical fiber 11 for lighting light transmission held by a mouthpiece 20 made of metal is inserted and fixed to a fixing member 21 which is a holding member provided to the connector. In addition, an opening 24 for incident light is provided at one end of the fixing member 21, and a cover glass 24 is fixed by staking, etc. to this opening 24, whereby the watertight structure is formed. In this way, the optical fiber 11 may be made watertight. Further, the heat rays from a lamp 17 are absorbed by a lens 25; therefore, the surface of the incident end 15 of the optical fiber 11 may be protected from heat hazards. |
