Abstract
A projection lens is configured to be attached to a housing of a projection apparatus having an electro-optical element. The projection lens includes a first holding portion that holds a first optical system disposed along a first optical axis through which light from the housing passes, a first reflection portion that bends light having the first optical axis into light having a second optical axis, a second holding portion that holds the first reflection portion, and a second holding portion fixing mechanism that fixes the second holding portion to the first holding portion. By weakening a fixing force of the second holding portion fixing mechanism, the second holding portion can be shifted relative to the first holding portion.
