The opening extends through the housing from a first side to a second side of the housing, and includes a first space and a second space. The light guide is disposed across the first space and the second space. The housing has a wall surface that faces the second space and contacts the light guide, a guide rib that extends in a second direction, and a fitting wall that extends in a third direction. The light guide has a first contact surface that contacts the wall surface so as to position the light guide in a first direction, and a guide groove that is fitted to the guide rib so as to position the light guide in the third direction while guiding movement of the light guide in the second direction.
