Abstract:
A projector according to an aspect of the present disclosure includes an optical path changer that is provided between an image formation unit and an projection optical unit and changes the optical path of image light from the image formation unit, a linkage frame that links the image formation unit and the projection optical unit to each other, and a vibration absorbing member that absorbs vibration generated by the optical path changer. The optical path changer includes a base member, an optical member, and a swing frame that supports the optical member and is swingably supported relative to the base member. The vibration absorbing member has vibration absorbing surfaces that are in contact with the base member of the optical path changer, and the vibration absorbing surfaces are in contact with support surfaces of the linkage frame to cause the support surfaces to support the optical path changer.
