Turn indicator lamp and a saddle-straddling type motor vehicle including the same

A lens (30) is supported at a reflector member (40) by a lens supporter (42), and a light emitter (50) is supported by the reflector member (40). In this state, a valve (52) of the light emitter (50) is positioned in an emission space of the reflector member (40), and a light-emitting module in which the lens (30), the reflector member (40) and the light emitter (50) are integrally coupled is constituted. The light-emitting module is attached in a storage space (20S) of a main body storage (20). A direction of opening of a first opening (21) and a direction of opening of a second opening (22) of the main body storage (20) intersect with each other. The reflector member (40) supports the light emitter (50) such that a wiring connector (51a) of the light emitter (50) is positioned in an inner space of a main body supporter (10) through the second opening (22) in the storage space (20S).
