  • Patent number: 9718394
    Abstract: A headlight-affixing structure for affixing a headlight positioned above a front bumper to a vehicle by using a headlight bracket. When viewed from the front, the headlight bracket is substantially formed into an L-shape and comprises a horizontal section extending in the vehicle-width direction along the lower edge of the headlight, and an upright section extending upward from an end of the horizontal section on the inside thereof in the vehicle-width direction. The upright section of the headlight bracket is provided with an upper affixing part for affixing the upper section of the headlight by using a downward-facing fastening member. The middle-outside section of the horizontal section is provided with a lower affixing part for affixing the lower section of the headlight by using an upward-facing fastening member.
