Description

[Technical field]

[0001] The present invention relates to a vehicle lamp in which at least a portion of a lamp unit in a lamp chamber is supported by a support member. [Background technology]

[0002] A lamp unit that is disposed within a lamp chamber of a vehicle lamp and forms a predetermined light distribution is supported by a lamp housing directly or indirectly via a support member (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2020-27690 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there are only a limited number of locations in a narrow lamp chamber where the lamp unit and the support member can be attached. When a lamp unit that emits light forward is arranged at the front of the lamp chamber using a support member, the lamp unit may be attached to the front side of the support member, and the support member itself may be attached to the lamp housing at the rear side of the support member. If the support member itself is not supported at the front side and is only attached at the rear side, the support member will be supported in a cantilevered state. In such a case, the weight of the lamp unit is likely to cause the front side of the support member to vibrate, and the lamp unit may interfere with other parts due to the vibration. Since the front of the lamp chamber where the lamp unit is arranged is a design part that can be seen from the outside, scratches and powdering due to interference will impair the design of the lamp fixture.

[0005] The present invention has been made in view of the above, and provides a vehicle lamp that suppresses vibration of a lamp unit in a lamp chamber. [Means for solving the problem]

[0006] In order to solve the above problems, in a vehicle lamp of a certain configuration according to the present disclosure, there are a lamp body with an opening at the front, a lamp cover at least partially composed of a translucent resin, which is attached to the opening of the lamp body and forms a lamp chamber inside, a lamp unit disposed in the lamp chamber, which forms a predetermined light distribution and irradiates forward, and a support member disposed in the lamp chamber, which supports at least a part of the lamp unit. At least a part of the lamp unit is attached to the front side of the support member, and on the rear side of the support member, there is provided an attachment portion for the support member itself to be directly or indirectly attached to the lamp cover or the lamp body. The support member is supported only at the attachment portion, and the support member is configured to be provided with a protruding portion that protrudes rearward from the rear end portion and abuts against a ceiling surface that forms a part of the upper surface of the lamp chamber.

[0007] According to this aspect, since the support member is supported only on the rear side, it is in a cantilever-supported state. However, a protruding portion is formed in the direction opposite to the front where the lamp unit is attached, and the protruding portion abuts against the ceiling surface. By abutting against other parts above and rearward with respect to the front side that tends to sink downward due to its weight, the vertical moment force due to sinking is suppressed, and the rigidity of the support member is strengthened by the increase in the contact points, thereby suppressing the vibration of the support member and the lamp unit attached thereto.

[0008] Also, in a certain aspect, the protruding portion is configured to extend obliquely upward from the horizontal and abut against the lamp body at the extending end portion. According to this aspect, the extending end portion of the protruding portion reliably abuts, and the vibration is suppressed.

[0009] Also, in one aspect, the lamp unit is one of the combination lamps having a plurality of lamp units, and is configured to be disposed above in the lamp chamber. According to this aspect, it is not possible to contact the lower lamp unit, but the lower part cannot be fixed by the lower lamp unit and is supported only by the upper lamp chamber ceiling surface. In the cantilever state supported by the ceiling surface, the free end is more likely to sink downward, but the protruding portion can be easily brought into contact with the ceiling surface, which is suitable for this configuration.

[0010] Also, in one aspect, the protruding portions are configured to be provided at intervals from each other. By appropriately providing the protruding portions at necessary parts, it is possible to avoid interference with other components and suppress vibration.

[0011] Also, in one aspect, ribs or side walls are provided on the protruding portion. The ribs and side walls improve the rigidity of the protruding portion and thus the entire support member, suppressing vibration.

Advantages of the Invention

[0012] As is clear from the above description, it is possible to provide a vehicle lamp that suppresses the sway of the lamp unit in the lamp chamber.

Modes for Carrying Out the Invention

[0014] Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The embodiments are illustrative and do not limit the invention, and all features and combinations described in the embodiments are not necessarily essential to the invention. In addition, in the following description of the embodiments and modifications, the same configurations are given the same reference numerals, and duplicated descriptions are omitted as appropriate. In this specification, the vehicle and the vehicle lamp are described as being (upper: lower: left: right: front: rear = Up: Lo: Le: Ri: Fr: Re) based on the driver's viewpoint of the vehicle on which the vehicle lamp is mounted.

[0015] (Vehicle Lighting 1) Fig. 1 is a front view of a vehicle lamp 1 according to a preferred embodiment of the present invention. The vehicle lamp 1 is a headlamp mounted on the left and right corners of the front of a vehicle. The vehicle lamps 1 are provided in a pair on the left and right, and are configured symmetrically to each other. The following description focuses on the vehicle lamp 1 mounted on the left side.

[0016] The vehicle lamp 1 comprises, as a lamp housing, a lamp body 2 and a lamp cover 4. The lamp body 2 is open at the front, and the lamp cover 4 is attached to the opening, defining a lamp chamber S inside.

[0017] The vehicle lamp 1 is a combination lamp that houses four lamp units LU1 to LU4 in a lamp chamber S. Each of the lamp units LU1 to LU4 is equipped with a light source that is a light-emitting element, and forms the light emitted from the light source into a predetermined lamp light distribution and emits it forward of the vehicle.

[0018] The first lamp unit LU1 is a turn signal lamp unit, and is disposed along the upper edge of the lamp chamber S to extend in the vehicle width direction.

[0019] The second lamp unit LU2 serves both as a daylight running lamp unit and a clearance lamp unit, and is disposed below the first lamp unit LU1, extending in the vehicle width direction in the same manner as the first lamp unit LU1.

[0020] The third lamp unit LU3 and the fourth lamp unit LU4 are arranged side by side in the vehicle width direction in the lower region of the second lamp unit LU2. The third lamp unit LU3 is a low beam lamp unit and is arranged on the inner side in the vehicle width direction, and the fourth lamp unit LU4 is a high beam lamp unit and is arranged on the outer side in the vehicle width direction. The lamp units LU3 and LU4 respectively form a low beam light distribution / high beam light distribution and irradiate the front of the vehicle.

[0021] The third lamp unit LU3 and the fourth lamp unit LU4 are configured to be larger than the first lamp unit LU1 and the second lamp unit LU2, and are arranged occupying a large area in the lamp chamber S, including not only the lower region but also the central region of the lamp chamber S.

[0022] FIG. 2 is a longitudinal sectional view taken along the line A-A of FIG. 1. As shown in FIG. 2, the lamp body 2 is configured in a box shape with an open front, and a flange portion 2a is provided over the entire circumference at the opening. Similarly, the lamp cover 4 is configured in a box shape with an open back, and a flange portion 4c is provided around the opening. The lamp cover 4 is attached to the lamp body 2 by welding the flange surfaces of the two flange portions 4c and 2a together, and a lamp chamber S is formed inside.

[0023] The lamp cover 4 is composed of a light-transmitting portion 4a made of a light-transmitting resin member and a non-light-transmitting portion 4b that surrounds the outer peripheral edge of the light-transmitting portion 4a in a frame shape. The light-transmitting portion 4a is mainly arranged on the front surface of the lamp chamber S and transmits the light emitted from the lamp chamber S as a transmissive lens (outer lens). The aforementioned flange portion 4c is formed on the non-light-transmitting portion 4b.

[0024] The lamp cover 4 is formed to fit the body shape of the vehicle, and a step portion 4d is formed on the top surface, which bends vertically downward from the horizontal plane of the opening where the flange portion 2a is molded, from the opening on the back toward the front, and then bends further forward from the bent end. The ceiling surface of the lamp chamber S is composed of the ceiling surface of the lamp cover 4 and the ceiling surface of the lamp body 2, but the proportion of the lamp cover 4 is relatively large, and the joint surface between the lamp cover 4 and the lamp body 2 is closer to the rear than the center in the front-to-rear direction.

[0025] The first lamp unit LU1 and the second lamp unit LU2 are attached to a support member 50 and disposed above and in front of the lamp chamber S.

[0026] Regarding the configuration of the lamp units, the third lamp unit LU3 will be described first. The third lamp unit LU3, which is a low beam lamp unit, is a reflector type lamp unit and includes a light source 31, which is a light emitting element, and a step reflector 32 that is divided into multiple reflective elements.

[0027] The light source 31 is attached to a flat eaves portion 33 provided above the step reflector 32 with its light-emitting surface facing downward in the vertical direction. The light source 31 may be a semiconductor light-emitting element such as an LED (Light Emitting Diode), an LD (Laser Diode), or an EL (Electro Luminescence) element, or a light bulb, an incandescent lamp (halogen lamp), or a discharge lamp (discharge lamp). The step reflector 32 is configured to be wide in the vehicle width direction (left-right direction), and multiple light sources 31 are attached to the eaves portion 33 at equal intervals in the left-right direction.

[0028] The step reflector 32 has an inner surface that is a reflective surface that reflects light, and is configured to reflect the light L3 emitted from the light source 31 to form a low beam light distribution and irradiate the light in front of the vehicle.

[0029] A support portion 34 for supporting the step reflector 32 is provided on the back surface of the step reflector 32. The support portion 34 is configured in the shape of a flat plate extending in the vertical direction, and is molded integrally with the step reflector 32 and the eaves portion 33 by injection molding.

[0030] A through hole penetrating in the front-rear direction is provided in the support portion 34. A mount M is attached to the through hole, and an aiming screw E screwed into the mount M is attached to the rear surface of the lamp body 2.

[0031] 1, the aiming screws E that are inserted into the through holes are provided in three locations on the support portion 34, spaced apart from each other on the left and right and front and rear. Here, the fourth lamp unit LU4 is a lamp unit that forms a high beam light distribution, and the fourth lamp unit LU4 is also held by the support portion 34. As long as the fourth lamp unit LU4 is a lamp unit that forms a high beam light distribution, it does not matter what configuration it is, such as a reflector type or a direct type, and detailed description thereof will be omitted.

[0032] When each aiming screw E is rotated clockwise or counterclockwise, the aiming screw E advances or retreats due to the screw feed action. Accordingly, the support portion 34 tilts, and the optical axis of the lamp units LU3 and LU4 is adjusted. Since the optical axis directions of the lamp units that form high beam and low beam light distributions are legally determined, the third lamp unit LU3 and the fourth lamp unit LU4 are configured so that the optical axis directions can be adjusted by tilting using the aiming screw E and the support portion 34 even after being placed in the lamp chamber S.

[0033] Next, the first lamp unit LU1 will be described. The first lamp unit LU1 includes a light source 11, a substrate 12 on which the light source 11 is mounted, and a first light guide 13.

[0034] The first light guide 13 is an optical member formed by injection molding a transparent resin member such as acrylic or polycarbonate. The first light guide 13 has a generally flat rectangular parallelepiped shape except for the light entrance portion, with the largest surface being the upper surface and the elongated end surface facing forward. The end surface facing forward is configured as the exit surface 13f of the first light guide 13.

[0035] A part of the rear region of the upper surface of the first light guide 13 protrudes upward and is configured as a light incident portion of the first light guide 13, and the substrate 12 is placed and supported on the upper end of the light incident portion. A light source 11 is attached to the lower surface of the substrate 12 with its light emitting surface facing vertically downward. Here, since the first lamp unit LU1 is a turn signal lamp unit, an LED that emits amber light is used as the light source 11. In the lower region of the substrate 12, the surface of the first light guide 13 facing the light source 11 configures the incident surface 13a and the first reflecting surface 13d.

[0036] The incident surface 13a of the first light guide 13 has an optical function of guiding the light emitted from the light source 11 into the first light guide 13, and has a first incident surface 13b consisting of an aspheric surface approximating a hyperbolic surface on the light source 11 side, with the optical axis of the light source 11 (in the direction perpendicular to the substrate 12) as its principal axis and the position of the light source 11 on the principal axis as its focal position, and a second incident surface 13c that is approximately cylindrical and extends from the upper edge of the first incident surface 13b toward the light source 11 side so as to surround the first incident surface 13b.

[0037] The light sources 11 are provided in multiple numbers on the underside of the substrate 12, spaced apart in the left-right direction, and a concave incident surface 13a is formed for each light source 11 immediately in front of the light source 11, with the concave bottom surface forming a first incident surface 13b on the light source 11 side which is made of a hyperbolic surface or an aspheric surface approximating a hyperbolic surface, and the concave side surface forming a second incident surface 13c which is approximately cylindrical.

[0038] The first reflecting surface 13d has an optical function of internally reflecting the light guided into the first light guide 13 and returning it into the first light guide 13, and is composed of an annular inclined surface that opens outward on the side of the second incident surface 13c from the end of the second incident surface 13c toward the opposite end.

[0039] A conical notch is formed on the surface facing the incident surface 13a of the first light guide 13, with a perpendicular line from the apex coinciding with the optical axis of the light source 11, and the surface of the cone is configured as a second reflecting surface 13e. The second reflecting surface 13e is also configured to return (total reflect) the light guided into the first light guide 13 back into the first light guide 13.

[0040] The front end, exit surface 13f, has steps formed all over it to diffuse the light, giving it light diffusion properties, and exit surface 13f has the optical function of emitting the guided light outside first light guide 13, i.e., in front of the lamp.

[0041] Amber light L1 emitted from the light source 11 travels toward the first entrance surface 13b and the second entrance surface 13c that constitute the entrance surface 13a of the first light guide 13 located immediately before the light source 11. The entrance surface 13a guides the light L1 into the first light guide 13. In the first light guide 13, the light L1 is guided while repeatedly undergoing diffuse reflection toward the exit surface 13f. Due to the light diffusion characteristics of the exit surface 13f, the light L1 guided inside the first light guide 13 travels toward the exit surface 13f while diffusing radially, passes through the light-transmitting portion 4a, and is irradiated forward of the vehicle. The light L1 is visually recognized as a horizontal line of amber light in the vehicle lamp 1.

[0042] The second lamp unit will be described. The second lamp unit LU2 includes a second light guide 21, a reflector 22, and a holder member 23. The second light guide 21 is a rod-shaped optical member, and is formed by injection molding a transparent resin member such as acrylic or polycarbonate, similar to the first light guide 13.

[0043] The second light guide 21 is disposed so that its longitudinal direction coincides with the left-right direction of the vehicle lamp 1, and is disposed so as to extend generally from one end of the lamp chamber S to the other end.

[0044] A side end surface along the longitudinal direction of the second light guide 21 is a light incident portion, and a light emitting element (not shown), such as an LED that emits white light, is disposed with its light emission direction facing the side end surface serving as the light incident portion.

[0045] The front side along the longitudinal direction of the second light guide 21 is configured as an exit surface 21a that emits light. The back side of the second light guide 21 is formed with a reflecting surface 21b having a plurality of steps (not shown) that reflects light traveling inside the second light guide 21 toward the exit surface 21a. Light L2 emitted from a light emitting element (not shown) enters the second light guide 21 from a side end face of the second light guide 21, is guided inside the second light guide 21 while repeating total reflection, enters the reflecting surface 21b, is reflected toward the exit surface 21a, and is emitted forward from the exit surface 21a.

[0046] The reflector 22 is formed long in one direction with approximately the same length as the second light guide 21, and has a dogleg shape in vertical cross section in the longitudinal direction, with an opening facing the forward light-transmitting portion 4a, and the second light guide 21 is held in the central curved portion. The inside of the reflector 22 is a reflective surface that reflects light, and is configured to guide the light emitted from the second light guide 21 forward. Since the light L2 incident on the second light guide 21 travels through the second light guide 21 while repeatedly being diffusely reflected, the light L2 reflected by the reflective surface 21b of the second light guide 21 and emitted from the emission surface 21a includes not only the light emitted in the horizontal direction but also the light emitted at an angle upward or downward from the horizontal direction. The light emitted upward or downward at a predetermined angle or more from the horizontal direction reaches the reflector 22, is reflected by the inner reflective surface, and is irradiated as reflected light toward the front of the lamp. In this way, by using the reflector 22, the light utilization efficiency is improved.

[0047] The holder member 23 is a two-color molded product formed by integrally injection molding a light-transmitting portion 23a made of a transparent (clear) resin material having light transmittance and a non-light-transmitting portion 23b made of a non-light-transmitting resin. The light-transmitting portion 23a is formed long in one direction. The non-light-transmitting portion 23b extends outward so as to extend the upper and lower edges of the light-transmitting portion 23a, and is configured to bend from the upper end portion and extend toward the rear. The vertical cross-sectional shapes of the second light guide 21 and the reflector 22 are substantially the same regardless of the position in the longitudinal direction at which they are cut, and the cross-sectional shape of the holder member 23 is an inverted U-shape.

[0048] The holder member 23 holds the reflector 22 by sandwiching it between the upper and lower extending portions with the opening of the reflector 22 facing forward. The light-transmitting portion 23a is positioned so as to be located at the opening of the reflector 22. The light-transmitting portion 23a acts as an inner lens of the second lamp unit LU2, and the non-light-transmitting portion 23b acts as a reflector holder and a bracket member.

[0049] Light L2 emitted forward through the second light guide 21 and the reflector 22 passes through the transparent light-transmitting portion 23a and then through the transparent light-transmitting portion 4a, and is visually recognized as a single line of white light extending horizontally overall.

[0050] (Support member 50) The support member 50 to which the first lamp unit LU1 and the second lamp unit LU2 are attached will now be described. Fig. 3 is a cross-sectional perspective view of the bracket unit taken along line AA in Fig. 1.

[0051] The support member 50 is an injection-molded resin member, and is configured to be thin overall. The first lamp unit LU1 and the second lamp unit LU2 are attached to the support member 50 and disposed at predetermined positions within the lamp chamber S.

[0052] The support member 50 includes a staircase portion 50a for holding the lamp units LU1 and LU2, a vertical wall 50c which serves as a standing wall at the rear end of the staircase portion, and a protrusion 50d which protrudes rearward from the back surface of the vertical wall 50c.

[0053] The vertical wall 50c is formed with a through hole 50e penetrating in the front-rear direction. The joint surface 2b of the flange portion 2a of the lamp body 2 is provided with a mounting hole 2c formed in the front-rear direction with the opening facing forward, and the support member 50 is fastened to the lamp body 2 by inserting a tapping screw N through the through hole 50e and screwing it into the mounting hole 2c. The mounting hole 2c is formed only in a partial area of ​​the flange portion 2a, which is the upper part of the lamp chamber S, and the flange portion 2a is configured to be thick and wide in order to provide the mounting hole 2c. In this area, the mounting hole 2c is provided in an area of ​​the joint surface 2b close to the lamp chamber S, and the lamp cover 4 is attached to an area farther away from the lamp chamber S. The support member 50 is attached to the lamp body 2 by the through hole 50e, and the through hole 50e corresponds to the mounting portion in the present claim. The mounting portion of the support member 50 is not limited to a through hole, and other well-known mounting configurations such as an engagement protrusion, a lance fixing structure, or a concave-convex fitting may be used as long as the support member 50 is configured to be mounted directly or indirectly via other parts to the lamp body 2 or lamp cover 4, which is the lamp housing.

[0054] A step portion 50a is formed continuously from the lower end of the vertical wall 50c toward the front and downward. A holder member 23 supporting the second light guide 21 and the reflector 22 is attached to the horizontal surface of the frontmost tip of the step portion 50a. In addition, the first light guide 13 is placed across the upper surface of the holder member 23 and the rearmost horizontal surface of the step portion 50a, and is attached to the support member 50 with the exit surface 13f aligned with the tip end of the step portion 50a. A substrate 12 on which a light source 11 is mounted is attached to the first light guide 13. That is, all of the components of the first lamp unit LU1 and the second lamp unit LU2 are directly or indirectly attached to the support member 50.

[0055] The protruding portion 50d is formed in a flat plate shape, and extends rearward from the back surface of the vertical wall 50c in a direction slightly upward rather than horizontally, and is provided at a slight incline from the horizontal state. The extending point and inclination angle are adjusted so that, in a state in which the support member 50 is fastened to the lamp body 2 with the tapping screw N, the extending end portion 50h of the protruding portion 50d abuts against the inner surface of the lamp body 2 (hereinafter referred to as the ceiling surface 2d) that constitutes a part of the ceiling surface of the lamp chamber S.

[0056] The shape of the support member 50 excluding the protrusions 50d is generally extruded in one direction, and the longitudinal cross-sectional shape in the longitudinal direction is generally the same regardless of the position in the longitudinal direction when cut. A plurality of protrusions 50d are provided at intervals in the longitudinal direction of the vertical wall 50c. The protrusions 50d are formed at positions in the longitudinal direction of the support member 50 where the through holes 50e of the vertical wall 50c are formed, and the protrusions 50d are provided protruding from the back surface of the lower part of the through holes 50e of the vertical wall 50c.

[0057] The protruding portion 50d is provided with a plurality of ribs 50g on the lower side thereof in order to increase the rigidity. The protruding portion 50d provided on the end portion of the support member 50 is formed integrally with a side wall 50f, and the side wall 50f is configured as a vertical wall of the protruding portion 50d, thereby increasing the rigidity of the protruding portion 50d.

[0058] (Action and effect) Providing the protrusion 50d on the support member 50 suppresses vibration of the support member 50 and the lamp units LU1, LU2 attached thereto. This will be described in detail.

[0059] To emit light forward of the vehicle, the lamp units LU1, LU2 are attached to the front end of the support member 50 and disposed in the vicinity of the lamp cover 4. Since the lamp units LU1, LU2 are attached to the front side of the support member 50 and the support member 50 is supported by the lamp body 2 only at the through-hole 50e of the vertical wall 50c provided on the rear side, the support member 50 and the lamp units LU1, LU2 attached thereto are cantilevered in the front-to-rear direction.

[0060] Here, when the protruding portion 50d is not provided on the support member 50, the front tip of the support member, which is the free end of the cantilever support, is likely to vibrate vertically, and the lamp units LU1 and LU2 attached to the tip also act as weights and the swing amplitude becomes large. When the swing amplitude of the vibration of the support member becomes large, there is a risk of interference with other components, particularly the lamp cover in the vicinity. The lamp cover is a place that is visible from the outside, and scratches due to interference become a major problem that impairs the design. In the present embodiment, a protruding portion 50d that protrudes rearward in a direction opposite to the front side where the lamp units LU1 and LU2 are attached is provided on the support member 50, and the extending end portion 50h of the protruding portion 50d is brought into contact with the ceiling surface 2d of the lamp chamber S. In the support member 50, since the front side tends to sink downward due to the weight of the lamp units LU1 and LU2, when the protruding portion 50d on the rear side contacts the ceiling surface of the lamp body 2, the sinking is suppressed against the moment acting downward and forward. In addition, the rigidity of the support member 50 is strengthened by the increase in the contact points due to the protruding portion 50d, the deflection of the support member 50 is reduced, and the vertical vibration of the support member 50 and the lamp units LU1 and LU2 attached thereto is suppressed. Similarly, by providing ribs 50g and side walls 50f on the protruding portion 50d, the rigidity of the protruding portion 50d and the vertical wall 50c is increased, the deflection of the support member 50 is reduced, and the vibration of the support member 50 is further suppressed.

[0061] The protruding portion 50d is provided so as to project in the lower region of the through hole 50e provided in the vertical wall 50c. The through hole 50e of the support member 50 is a portion fastened to the lamp body 2 with a tapping screw N. In a state where the support member 50 is attached to the lamp body 2, the vicinity of the through hole 50e is a portion having relatively high rigidity in the support member 50. By providing the protruding portion 50d in the vicinity of the through hole 50e, the rigidity of the protruding portion 50d to which the load is applied is increased. In addition, when the rigidity of the support member 50 is improved, the amount of deformation is reduced and the occurrence of problems such as cracking is suppressed.

[0062] The protrusion 50d protrudes at an incline toward the rear and upward, and the extending end 50h of the protrusion 50d reliably abuts against the ceiling surface. In addition, by abutting at the extending end 50h, which is the furthest from the front end, the resistance against the moment that the front end tries to sink due to the weight is strengthened. In this embodiment, since the tip of the support member 50 extends forward and downward, the protrusion 50d extends and abuts in the opposite direction, that is, upward and rearward, so that the resistance against the moment is further strengthened.

[0063] In this embodiment, the extension end 50h of the protrusion 50d is brought into contact with the ceiling surface with a zero clearance, but it may be brought into contact with a negative clearance by applying a force. The contact can be achieved without considering design errors, manufacturing errors, installation errors, and the like.

[0064] The configuration is not limited to one in which all of the components of the lamp units LU1 and LU2 are attached to the support member 50, and the configuration of the present disclosure can be applied as long as at least a part of one of the lamp units is attached.

[0065] The vehicle lamp 1 is a combination headlamp, and the lamp units LU3 and LU4 arranged below the lamp chamber S require optical axis adjustment, and are supported by the lamp body 2 so that their optical axes can be adjusted. On the other hand, the lamp units LU1 and LU2 arranged above the lamp units LU3 and LU4 do not require optical axis adjustment. The lamp units LU1 and LU2 cannot be placed or supported on the lamp units LU3 and LU4, whose position may change due to optical axis adjustment. The lamp units LU1 and LU2 need to be arranged at a predetermined distance from the lamp units LU3 and LU4 so that they do not interfere with each other even if they are tilted due to optical axis adjustment. The distance is determined in consideration of the vibration of the lamp units LU1 and LU2 and the support member 50 that supports them, and the formation of the protruding portion 50d can reduce the maximum vibration amplitude of the lamp units LU1 and LU2, so that the distance can be reduced. This improves the degree of freedom in the design of the arrangement and parts in the lamp chamber S.

[0066] The protrusions 50d are provided in a plurality of intervals, and are configured to suppress vibrations while avoiding interference with other components such as wiring (not shown). The protrusions 50d are flat, and the ceiling surface 2d and the extending end 50h are in line contact. The contact area is increased, and vibrations are further suppressed. The shape and contact configuration of the protrusions 50d are not limited to this embodiment, and the protrusions 50d may be formed to match the shape of the ceiling surface 2d to make surface contact, or may be bent upwards after extending horizontally backwards to abut against the ceiling surface.

[0067] The configuration of the present disclosure is not limited to headlamps and combination lamps, but can be widely applied to various vehicle lamps equipped with lamp units such as turn signal lamps, clearance lamps, and stop lamps, as well as rear combination lamps, tail lamps, cornering lamps, hazard lamps, positioning lamps, back lamps, fog lamps, and accessory lamps. Note that the light irradiation direction of the vehicle lamp 1, which is a headlamp, is the direction in which the lamp mainly irradiates light, and the directions of each component have been described as coinciding with the forward direction of the vehicle, but this is a relative direction, and it goes without saying that the extending direction of the lamp and supporting member will change relative to the vehicle depending on the mounting direction of the lamp on the vehicle.

[0068] The above describes preferred embodiments of the present invention. However, the above embodiments are merely examples of the present invention, and these can be combined based on the knowledge of those skilled in the art, and such forms are also included in the scope of the present invention.
