ABSTRACT:
An optical conduction unit (U) has a configuration in which one portion (Sb) and another portion (58a) of an optical conduction body (5) are mated in mutually orthogonal x, y directions with first and second fitting means (64), (64a) of the first member (60A) of a reflector (6). A portion (65b) and another portion (65c) of the second member (60B) of the reflector (6) are mated in the x, y directions with the third and fourth fitting means (64b), (64c) of the first member (60A). With such a configuration, the reflector (6) and optical conduction body (5) can be reliably assembled so that they cannot be easily separated.
