Abstract
A projection lens, which is a projection lens to be attached to a projection apparatus body having an electro-optical device, includes: a first focus optical system; a first holding portion that has an attachment portion and on which light along a first optical axis extending in first directions is incident; and an adjustment frame that holds the first focus optical system. When one of the first directions is defined as a first A direction and the other of the first directions is defined as a first B direction, the first focus optical system is positioned further in the first A direction than the attachment portion, and light along the first optical axis travels in the first B direction. The adjustment frame is movable in the first directions relative to the first holding portion.
