| 摘要 | An indicator disposed on an openably closable door disposed on a part of an exterior panel includes a light source disposed on a housing positioned in an interior of the door and a diffusion lens disposed on the door and opposed to the light source, wherein the light source is mounted on a support part disposed on the housing so that an optical axis of the light source is coincident with that of the diffusion lens. The door includes a recessed portion including a retainer, and the diffusion lens is supported in the recessed portion with the retainer pressing an external surface of the diffusion lens entirely so that the light from the light source is prevented from leaking from the surface of the door. | ||
