VEHICULAR LIGHTING FIXTURE

Provided is a vehicular lighting fixture capable of reducing influence of aberration and heat in a projection lens and projecting a light pattern with high accuracy. The vehicular lighting fixture includes a projection lens (2) that projects light emitted from a light source (3) to project a required light distribution pattern. The projection lens (2) includes, in this order from the side opposite to the light source (3), a first lens (21) and a second lens (22) made of resin, and a third lens (23) and a fourth lens (24) made of glass. A diaphragm (25) that limits the diameter of the projected light is disposed between the second lens (resin lens) (22) and the third lens (glass lens). By squeezing the diaphragm (25), the aberration of the projection lens (2) is reduced. Further, the diaphragm (25) reduces transfer of heat of the light source (3) from the third lens (23) side toward the second lens (22) side.
