Abstract:
A rib, provided on an outer periphery of a projection ring, includes: a first rib extending along a direction in which an optical axis of a lens main body extends (an attachment direction of a focus lens); and a second rib, brought into contact with one end of first rib, extending along a direction approximately orthogonal to first rib so as to have one side and the other side. On the other hand, a protrusion, provided on an inner periphery of the cylindrical focus ring, includes a pair of protrusion parts arranged with a spacing in a direction in which an optical axis extends. With this structure, it is possible to obtain a projector having a focus ring capable of being easily attached to a lens main body and being easily molded.
