A head lamp with a movable reflector. The headlamp includes a lamp body, a reflector with a light source mounted thereon, and an aiming mechanism interposed between the lamp body and the reflector (14) for tiltably supporting the reflector (14) with respect to the lamp body. The reflector tilts by the rotational movement of the aiming screw which is rotatably supported in a screw insertion hole formed on the lamp body. The screw insertion hole is formed by a tubular portion, and the front portion of the tubular portion includes divided swinging strips (53) which are resiliently deformable in the radial direction. The swinging strips engage with an engaging groove formed on the aiming screw to prevent the aiming screw from being detached from the lamp body. The aiming screw includes a rotatably supported portion formed of resin, a male screw portion, and a gear portion behind the rotatably supported portion. Further, the rotatably supported portion is unitarily formed with a skirt type resilient watertight rib (34b) in pressurized contact, and sliding contact, with the end surface of the backward extension of the tubular portion to ensure the resilient support of the aiming screw in the forward and backward direction and to ensure watertightness at the rotatably supported portion.
