照灯。 A concave mirror is provided in the lamp housing, a light source bulb is provided near the focal point of the concave mirror, and either the lamp housing or the concave mirror is supported by one ball joint and two screw means. In the automobile headlamp configured to be able to adjust the optical axis by the screw means, the screw means includes a nut member attached to the member to be adjusted, and a screw rod screwed to the nut member. a knob slidably fitted onto the screw rod, a stopper means for stopping the knob from sliding in a direction in which it comes out of the screw rod, and a clutch passive plate fixed to the screw rod. and the knob is provided with a clutch driving plate facing the clutch passive plate, and a clutch spring is interposed between the clutch driving plate and the knob, and the knob is connected to a threaded lever. The clutch spring is configured so that it is hardly compressed when it slides in the direction of coming out of the clutch spring and comes into contact with the stopper means. A spiral surface-shaped slope is provided on the other side so that the two members slide against each other, and when the knob rotates around the screw rod, the clutch spring is slid in the direction of compressing the clutch spring by the action of the spiral surface. An automobile headlamp characterized by being configured such that the
