Abstract: A projector includes an optical path change device placed between a light modulation device and a projection optical device. The optical path change device has an optical member holding part that holds an optical member that a light modulated by the light modulation device enters, and a supporting member that swingably supports the optical member holding part. The supporting member is supported by a holding member that holds the light modulation device or the projection optical device.

Abstract: A light source unit provided with a light-emitting element as a light source is attached to a rear wall section of a housing. The light source unit is attached to the housing, in the state where a socket is inserted in an opening formed in the rear wall section and an elastic seal member attached to the front end of the socket is pressed against the rear wall section. A rib extending toward a lamp rear side so as to surround at least the upper half section of the opening is formed on the rear wall section of the housing.
