Patent ID: 7207704

Claim:
A vehicular lamp comprising a container-shaped lamp body, a lens that covers a front face of the lamp body, a reflector which has a light source and is provided between the lamp body and the lens, and an aiming mechanism that tiltably supports the reflector with respect to the lamp body, wherein the aiming mechanism comprises at least one rotational fulcrum section and at least one distance adjustment section, the reflector is provided in the lamp body so as to be rotatable at the rotational fulcrum section, and the reflector and the lamp body are connected such that a distance therebetween is adjustable at the distance adjustment section, the distance adjustment section is comprised of an adjustment shaft, a gear member, and a receiving element, in which the adjustment shaft is comprised of a threaded shaft portion and a spherical end portion formed on a tip end of the threaded shaft portion, the gear member is comprised of: a shaft portion which is open at a front end thereof and in which a thread groove that meshes with the threaded shaft portion of the adjustment shaft is formed internally, a gear portion which is formed on a rear end of the shaft portion, at least two elastic pawls which protrude from an outer peripheral portion of the shaft portion, and an empty space which is defined by the pawl and formed on the shaft portion so as to allow flexure of the elastic pawls in a direction toward the shaft portion, and the receiving element is formed on a back surface of the reflector; and wherein the gear member is rotatably inserted in an insertion hole formed in the lamp body with the threaded shaft portion of the adjustment shaft meshed with the thread groove of the shaft portion, and with the elastic pawls engaged with the front end edge of the insertion hole, thus preventing the gear member from slipping out of the lamp body; the spherical end portion of the adjustment shaft is received by the receiving element so that the spherical end portion is prevented from rotating about an axis of the threaded shaft portion, the reflector is formed of a material having elasticity; the receiving element of the reflector is comprised of two wall portions, which protrude from the back surface of the reflector and positioned substantially parallel to each other, and an opening, which extends in substantially one direction and is fanned between eave portions that protrude toward each other from a rear end of the two wall portions; the spherical end portion of the adjustment shaft is formed with at least two protrusions which protrude in a direction intersecting the axis of the threaded shaft portion; and the spherical end portion is received by the receiving element trough the opening between the two wall portions, and the protrusions of the spherical end portion are engaged with the wall portions.
