Claim 1
Independent Claim
363 words
A vehicular headlamp, comprising: a box-like lamp body; an outer cover mounted on said body for defining a lamp room with said body; a main beam unit accommodated in said lamp room for radiating a main beam; a sub-beam unit accommodated in said lamp room for radiating a sub-beam, said sub-beam unit being constituted by a first projection type lamp having an elliptic reflector, a projection lens and a holder connecting said reflector to said projection lens; means for supporting said main beam unit and said sub-beam unit, said supporting means pivots within said lamp room together with said main beam unit and said sub-beam unit; and an aiming means for vertically and laterally pivoting said supporting means, said aiming means comprising a first aiming mechanism for vertically pivoting said supporting means and a second aiming mechanism for laterally pivoting said supporting means, said first vertical aiming mechanism comprises: a pivot axis fixedly connected on a back wall of said lamp body at an upper and substantially center position in the lateral direction thereof; a receiving member having a concave part fixed to said supporting means at an upper center position thereof; a ball member unitary formed with a front end of said pivot axis, said ball member being rotatably fitted in said concave part of said receiving member; an adjusting shaft having a threaded portion at a front half thereof rotatably supported on said back wall of said lamp body at a position lower than the position on which said pivot axis is supported; and a nut member fixed to said supporting means at a position lower than the position on which said receiving member is fixed, and said threaded portion of said adjusting shaft is threadably engaged with said nut, and said second lateral aiming mechanism comprising: an adjusting shaft having a threaded portion at a front half thereof rotatably supported on said back wall of said lamp body at a right most position thereof horizontally spaced apart from the position on which said pivot axis is fixed; and a nut member secured to said supporting means, said nut member being threadably engaged with said threaded portion of said adjusting shaft.
