In the present invention, a reflector (16) comprises: a first reflector (17) constituted by a resin material; a shade (18) constituted by a metal material and assembled to the first reflector (17); and a second reflector (19) constituted by a metal material and assembled to the first reflector (17). The first reflector (17) has: a plate-like body section (17b) in which is formed an opening (17a) through which light emitted from a light source passes; and an upper reflection part (17d) which is provided around the opening (17a) and reflects part of the light passing through the opening to the front of a vehicle. The body section (17b) has: first fixing parts (17e) with which the shade (18) is assembled and fixed from a first direction; and second fixing parts (17f) with which the second reflector (19) is assembled and fixed from a second direction different from the first direction.

Provided is a projection device that prevents glare of light emitted from an auxiliary lamp of a vehicle and suppresses a decrease in brightness of a light pattern projected onto a road surface. A projection device (1) mounted on a vehicle to project a light pattern onto a surrounding road surface includes a far distance side projection unit (2, 3) that projects a predetermined far distance side light pattern onto a relatively far position, and a near distance side projection unit (4) that projects a predetermined near distance side light pattern onto a relatively near position. The far distance side projection unit (2, 3) projects, as a light pattern (FOP, COP), the surface shape of a light emitting surface of an LED (12, 13) by a projection lens (22, 23). The near distance side projection unit (4) projects, as a light pattern (NOP), the opening shape of a shade opening (34) opened in a shade (30) that blocks light emitted from an LED (14), by a projection lens (24).

The present invention provides a bracket member for a lighting fixture for a vehicle, the bracket accommodating and securing at least a portion of a lamp unit that emits light forward and having a peripheral wall surface that opens in the front-rear direction and extends in the front-rear direction to partition the housing space of the lamp unit, wherein at least a portion of the peripheral wall surface serves as a double wall, and there is a partition wall that partitions the double wall and defines a small space that is sandwiched by the double wall and extends in the front-rear direction. Since a front wall and a back wall are not provided, the weight can be reduced correspondingly, and rigidity can be secured by the double wall and the partition wall inside the double wall.

A vehicle lamp includes: a combination unit (11A) including a low beam unit (18) that projects a low beam light distribution pattern and a high beam unit (20) that projects a high beam light distribution pattern above the low beam light distribution pattern. The high beam unit (20) is capable of road surface drawing. The combination unit (11A) is capable of switching between a first irradiation direction in which the low beam light distribution pattern irradiates a predefined low beam region and a second irradiation direction lower than the first irradiation direction. The high beam unit (20) is configured to execute road surface drawing and illuminate a road surface to complement the low beam light distribution pattern, when the first combination unit (11A) is directed in the second irradiation direction.

Provided is a bracket member having a bearing part provided on a side wall surface with the bearing part axially supporting a shaft body, the bracket member being configured such that: the side wall surface is a double wall comprising an inner wall and an outer wall and has formed therein a through hole that penetrates the inner wall and the outer wall; a recess is formed in the inner wall from an end surface of the inner wall to the through hole with the recess being recessed towards the outer wall, and a tongue part projecting toward the through hole is formed from an end of the recess that faces the through hole; and a shaft fitting part recessed in an arc shape is formed at the tip of the tongue part. By merely inserting the shaft body from the recess, the shaft body is inserted into the through hole, the tongue part serves as a stopper, and the shaft body can be fitted to the bearing part by a one-touch operation.

Provided are an image projection device and an image projection method capable of suppressing variation in an image formation position of an image due to pitching of a vehicle and improving the visibility of the image. An image projection device (100) for projecting a virtual image via a display unit includes an image emission unit (140) that emits an image for forming the virtual image as image display light, an acceleration acquisition unit (110) that acquires an acceleration applied to a vehicle, a vehicle information acquisition unit (120) that acquires driving state information on the vehicle, and an image position correction unit (130) that corrects a display position of the image based on the acceleration and the driving state information.
