A headlamp for an automobile includes a lamp body, a light source, a reflector, and an aiming mechanism. The aiming mechanism includes a screw insertion hole and an aiming screw operable to move the reflector by pivoting the aiming screw. The aiming screw includes a supported portion supported by the screw insertion hole, a male screw portion forward from the supported portion, and a pivotal movement operating force transmitted portion rearward from the supported portion. A front end side of the supported portion includes an elastic locking portion operable to pass through the screw insertion hole by being deformed elastically to an inner side in a radial direction, and a rear end side of the supported portion is integrally formed with an elastic rib brought into press contact with a peripheral edge portion on a rear end side of the screw insertion hole to fixedly position the aiming screw.
