Provided is a vehicle lamp unit which includes an optical system configured to form a light distribution pattern ahead of a vehicle; and a rotary light shielding member configured to block at least a part of light of a light source. The rotary light shielding member includes a spiral light shielding portion formed to change a blocked quantity of light of the light source as the rotary light shielding member rotates around a rotating axis. The light shielding portion is configured to form a plurality of light distribution patterns such that a position of a cutoff line extending in a direction crossing a horizontal direction changes in the horizontal direction. Further, the light shielding portion is configured such that a change of a position of an edge portion projected as a cutoff line becomes nonlinear in relation to a change of a rotational position of the rotary light shielding member.
