Abstract: A lamp unit is fastened to a bracket via screw fastening at two positions in the vehicle width direction where a rotation axis Ax1 of the lamp unit extends. Then, the bracket includes protrusions formed at four positions in the direction where the rotation axis Ax1 extends to allow the lamp unit to be rotated in the vertical direction by being in contact with a support panel of the lamp unit. Accordingly, with a simplified configuration, the contact portions of the four protrusions may function as fulcrums when the lamp unit rotated, and the lamp unit may be rotated in the vertical direction.

Abstract: Lamp piece units in a parabolic pillar type capable of forming a luminous intensity distribution pattern prolonged sideways are formed as side irradiating lamp piece units. Thereby, a portion of diffused and reflected light from reflectors of the respective side irradiating lamp piece units is prevented from being blocked by other lamp piece constituting members, even when a surface shape of a vehicular headlamp is flexed to the rear side. Further, although the respective side irradiating lamp piece units are constituted by the lamp piece units of the parabolic pillar type having an angular outer shape as a whole, a large depth space for arranging the units is dispensed with.
