Abstract
There is provided a lamp unit which is to be installed in a vehicle. The lamp unit includes a light source; a projector lens; a rotary shade that is disposed behind the projector lens so as to block a portion of the light emitted from the light source and that has a rotation axis; and a drive mechanism that rotates the rotary shade about the rotation axis. The rotary shade includes: a first end edge; a second end edge; and a twisted end edge that extends around the rotation axis so as to intersect with the first end edge and the second end edge. A first inclination angle is formed between the rotation axis and a first imaginary plane that is orthogonal to an optical axis of the projector lens.
