Abstract
A light-receiving device unit (as with a light-emitting device unit) has a body accommodated in a cylindrical hole in a housing, and a flange part secured by being pressed toward an end face of the housing by a protrusion of a bracket holder. The bracket holder comprises a tilted wall corresponding to an inclined wall of the housing, and reliably presses the light-receiving device unit while being slid along a slope when being inserted. Also, it engages an abutment of the housing by using a claw at the leading end of the protrusion.
