PROBLEM TO BE SOLVED: To reduce a possibility of heat deformation in a reflector of a head lamp for a vehicle whose light source bulb body is inserted in the reflector. SOLUTION: A circular wall 14j is formed on the periphery of a bulb inserting hole 14b of a reflector 14, and a bulb abutting surface 14k which abuts the main body supporting part 12c against the circular wall 14j from the back is formed. A notch 14m notched forward from the bulb abutting surface 14k is formed on the circular wall 14j, and the inner and outer spaces of the reflector 14 are communicated. Thereby the heat generated in the inner space of the reflector 14 is dissipated into the outer space via the notch 14m. Abutting between the main body supporting part 12c and the bulb abutting surface 14k is applied at three parts in a circumferential direction of the circular wall 14j, and three notches 14m are respectively formed at the three place, thereby the heat radiation property is increased. |
