  However, according to the conventional bumper guide portion structure shown in FIG. 8, dirt, dust, or the like is located in the back of the groove portion 103B between the lower surface 103b of the lens 103 and the bumper guide portion 108 supported by the flange 107a of the bumper 107 being inserted. The deposit T is deposited, and the deposit T is seen through the lens 103 so that the appearance quality of the vehicle is deteriorated. In addition, the accumulated deposit T such as the accumulated dust is the flange 107a of the bumper 107 and the bumper guide portion of the lens 103. There is a problem that the bumper 107 or the lens 103 is worn due to vibration or the like when the vehicle travels and abnormal noise is generated.

  Therefore, it is conceivable that the bumper guide portion 108 formed on the lens 103 is constituted by a plurality of ribs 108a as shown in FIG. 9, but even if such a configuration is adopted, the base portion of each rib 108a is the lens. Since they are continuously connected as a part of 103, as shown in FIG. 10, a deposit T such as dust accumulates at the base of each rib 108a. Since this deposit T accumulates in a narrow and deep part, it cannot be easily dropped by a car wash or the like. In this case, as shown in FIG. 10, if a bezel (extension) 110 that covers the periphery of the lens 103 is installed in the lamp chamber 104, the deposit T such as dust is covered by the bezel 110 so as to be externally provided. Although not visible, as shown in FIG. 11, in the headlamp 101 in which the bezel 110 is not installed, a deposit T such as accumulated dust is visible through the lens 103. In such a case, it is conceivable to form an uneven shape such as knurls in the range indicated by R on the surface on the lamp chamber 104 side behind the lower surface 103b of the lens 103, but this surface on which the uneven shape of the lens 103 is formed. Since the distance between the portion and the deposit T is close, the deposit T can be seen through the lens 103 and the aesthetic appearance is impaired.

  In order to solve the above problem, as shown in FIG. 12, the bumper guide portion 108 may be moved away from the lower surface of the lens 103 so that accumulated dust or the like cannot be seen through the lens 103. If it is adopted, it is necessary to add a new member 107b on the bumper 107 side, and a slide mechanism is required for the mold to form this member 107b, so that the mold structure becomes complicated and the cost cannot be avoided. Will occur.
