Abstract
A headlight device includes a light source, a base member, a light distribution formation member, a rotary member, a projection lens and a transmission mechanism. The base member holds the light source. The light distribution formation member forms a light distribution pattern. The rotary member holds the light distribution formation member and is held by the base member to be rotatable. The projection lens is held by the rotary member to be rotatable around a rotation axis orthogonal to a rotation axis. The transmission mechanism includes a transmission member for transmitting a rotation amount of the rotary member with respect to the base member to the projection lens and rotates the projection lens according to the rotation of the rotary member with respect to the base member.
