Description

The present invention relates to a vehicle lamp.

There are known vehicle lamps that can be assembled by attaching mounting components such as a reflector, inner lens, and outer lens to a mounting component such as a housing and engaging multiple components with each other.

Patent Document 1 discloses a vehicle lamp in which a lens and a lamp rim (attaching member) can be attached to a vehicle lamp body (attached member) in a specified attachment position. In the vehicle lamp disclosed in Patent Document 1, the lamp rim is attached to the lamp body using multiple fastening screws, but the legs of the lens engage with adhesive grooves in the lamp body at a position different from the position where it is fastened using the fastening screws. An adhesive is pre-loaded in the adhesive groove, and the legs of the lens are accommodated in the adhesive groove via the adhesive.

Japanese Utility Model Application Publication No. 1-126835

Conventional vehicle lamps, including the vehicle lamp disclosed in Patent Document 1, require a step of loading adhesive in advance into a groove (mounting portion) formed in the mounting member, and omitting this step means that movement of the lens legs (mounting portion) in the left-right direction (or width direction) is not restricted, and the legs come out of the adhesive groove. When the lens legs come out of the adhesive groove, the weight of the lens is applied to the lamp rim attached to the lens body below the lens, causing the lamp rim to lose its mounting position relative to the lamp body or to become misaligned relative to the lamp body, which could result in deformation of the lamp rim.

In particular, if the mounting member and the member to which the vehicle lamp is attached are long in one direction, the mounting member can be attached to the member to which the lamp is attached by fastening the mounting member to the member to which the lamp is attached in at least one location in that direction. However, due to restrictions on the shape of each member, it can be difficult to provide a fastening portion between the mounting member and the member to which the lamp is attached at a lower position and in a location sufficient to position the mounting member relative to the member to which the lamp is attached in that direction, or to prevent the mounting member from falling off the member to which the lamp is attached due to its own weight. In addition, if the mounting member is disengaged from the member to which the lamp is attached, this can lead to misalignment of members located near the mounting member or deformation of those members, which can lead to deformation or damage to the vehicle lamp.

As described above, in conventional vehicle lamps, it is possible to restrict the movement of the mounting structure relative to the mounting base in the up-down direction (second direction), but in order to also restrict movement in the left-right direction (first direction), the process of attaching the mounting structure to the mounting base is complicated and time-consuming.

The present invention provides a vehicle lamp that can restrict the upward movement of the mounting structure relative to the mounting member, restrict left-right movement, and has a simple installation process.

In order to solve the above problems, the present invention has the following configuration.

In the vehicle lamp of the present invention, the protruding piece engages with the claw portion in a first direction and with the receiving portion in a second direction, thereby restricting movement of the plate-shaped portion and the mounting member having it in the first and second directions.
Specifically, the downward or upward movement of the plate-shaped part and the workpiece comprising it is restricted by abutting the protruding piece against the claw portion in a first direction and arranging the tip of the plate-shaped part above or below the claw portion and abutting the claw portion from above or below. Also, the protruding piece abuts against the claw portion in the first direction, and the movement of the protruding piece, the plate-shaped part and the workpiece comprising it in the first direction is restricted without using adhesive or the like. According to the vehicle lamp of the present invention, by arranging the protruding piece near the base end of the claw portion and arranging the plate-shaped part above or below the claw portion, the movement of the mounting member in the first and second directions relative to the workpiece can be restricted and the mounting process can be simplified.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In the drawings, the dimensions of some components may be changed to different scales in order to make the components easier to see.

As shown in Figures 1 to 3, a vehicle lamp 10 according to one embodiment of the present invention is applied to a vehicle headlamp mounted in the front of a vehicle, for example, as a headlamp. The vehicle lamp 10 includes at least a housing (receiving member) 20, a light source 40, a reflector (mounting member) 50, an inner lens (not shown), and an outer lens 110 (second mounting member).

In the following description, unless otherwise specified, the terms "front," "rear," "left," "right," "upper," and "lower" refer to the respective directions when the vehicle lamp 10 is viewed from the front (front of the vehicle). Therefore, the respective directions when the vehicle is viewed from the back (rear of the vehicle) are reversed directions of front, rear, left, and right. In the following description, the left-right direction is the X direction (first direction), the left side is the +X side, and the right side is the -X side. The front-rear direction is the Y direction, the front side is the +Y side, and the rear side is the -Y side. The up-down direction is the Z direction (second direction), the upper side is the +Z side (one side of the second direction), and the lower side is the -Z side (the other side of the second direction).

The vehicle lamp 10 has a structure in which a reflector 50 and an inner lens and extension (not shown) are arranged in a lamp chamber formed by a housing 20 with an opening on the +Y side and a transparent outer lens 110 that covers the opening of the housing 20. As shown in FIG. 1, the reflector 50 is arranged on the +Y side of the housing 20 and is attached to the housing 20 from the +Y side.

The housing 20 is the main body of the vehicle lamp 10, and is formed so that the light source 40 and parts such as the inner lens and extension (not shown in FIG. 1) of the vehicle lamp 10 can be held in a predetermined position within the lamp chamber. The light emitted from the light source 40 travels approximately parallel to the Y direction. In other words, the Y direction is an example of the optical axis direction.

The housing 20 is a member to which the reflector 50 is attached, and includes a main body 26, a fixing portion 21, and a positioning portion 90, which are molded integrally with each other. The fixing portion 21 is provided to fix the reflector 50 to the housing 20, and has a plurality of fastening fixing portions 21A, 21B and a fastening fixing portion not shown.

The fastening parts 21A and 21B are provided at a distance from each other in the X direction on the outer periphery of the +Z side of the main body 26 of the housing 20 in the Z direction. The shape of the main body 26 when viewed along the Y direction is appropriately designed to fit the mounting location of the vehicle on which the vehicle lamp 10 is mounted. On the outer periphery of the main body 26, a plurality of fastening parts (not shown) including the fastening parts 21A and 21B are formed at appropriate intervals along the periphery. An insertion hole 29 is formed in each of the fixing parts 21, including the fastening parts 21A and 21B and the fastening parts not shown.

On the other hand, fastening parts 51A and 51B are provided at the outer periphery of the front side in the Z direction of the main body 56 of the reflector 50, which are spaced apart from each other in the X direction and can be fastened to the fastening fixing parts 21A and 21B when viewed along the Y direction. A plurality of fastening parts (not shown) including fastening parts 51A and 51B are formed at appropriate intervals along the periphery of the main body 56. Through holes 59 are formed in each of the fastening parts 51, including the fastening parts 51A and 51B and a fastening part not shown. When viewed along the Y direction, each of the insertion holes 29 overlaps with each of the through holes 59. The reflector 50 is fixed to the housing 20 by inserting a screw 60 into the insertion hole 29 by penetrating the through hole 59 along the Y direction from the +Y side.

The positioning portion 90 of the housing 20 positions the reflector 50 at a predetermined position relative to the housing 20. In this embodiment, the state in which the reflector 50 is positioned at a predetermined position relative to the housing 20 means that the housing 20 and the reflector 50 are positioned in a state in which the through hole 59 and the insertion hole 29 overlap in the Y-axis direction.

As shown in Figs. 1 and 2, the positioning portion 90 has a receiving portion 22, claw portions 24, 25, and a support portion 32. The receiving portion 22 is provided to receive the reflector 50. The receiving portion 22 is provided between the fastening portions 21A and 21B in the X direction of the outer periphery of the main body 26 of the housing 20. The receiving portion 22 extends from the outer periphery of the main body 26 between the fastening portions 21A and 21B to the +Y side.

As shown in FIG. 2, the claws 24 and 25 are formed on the receiving portion 22. The claws 24 and 25 form a pair and protrude from the tip of the receiving portion 22 on the +Y side and both sides in the X direction to the +Y side. The claws 24 and 25 are formed flat on the receiving portion 22 and flush with each other. An opening (opening) 28 is formed between the claws 24 and 25 in the X direction. The opening 28 is open in the Z direction and the Y direction, and is sandwiched between the side 24d on the -X side of the claw 24 and the side 25c on the +X side of the claw 25 in the X direction. The size (width) of the claws 24 and 25 in the X direction decreases as they move toward the +Y side. The width of the opening 28 in the X direction, i.e., the distance P between the claws 24 and 25 (size in the first direction) increases as they move toward the +Y side.

The support portion 32 is provided at a position on the outer periphery of the main body 26 of the housing 20 on the -Z side of the position where the receiving portion 22 is connected and overlaps with the receiving portion 22 in the X direction. The support portion 32 protrudes from the outer periphery of the main body 26 to the +Y side.

The support portion 32 includes an upper surface (opposing surface) 32a. The upper surface 32a is a surface on the +Z side facing the plate-shaped portion 52. A rib (bulging portion) 30 extending in the second direction can be formed from a portion of the upper surface 32a adjacent to the receiving portion 22. According to this embodiment, the rib 30 bulges from the upper surface 32a of the support portion 32 to the +Z side. The rib 30 is disposed within the opening 28 when viewed along the Z direction. The size of the rib 30 in the Y direction is larger than the size of the rib 30 in the X direction. That is, the rib 30 is formed longer in the Y direction than in the X direction. The end of the rib 30 on the -Y side is connected to the main body 26. The rib 30 is configured with a curved surface so as not to damage the reflector 50 when supporting the reflector 50 from the -Z side. In the housing 20, the main body 26, the receiving portion 22, the claw portions 24, 25, the support portion 32, and the rib 30 are molded integrally with each other.

The reflector 50 comprises a main body 56, a plate-like portion 52, and a protruding piece 54, which are molded integrally with each other. The shape of the main body 56 when viewed along the Y direction is the same as the main body 26 of the housing 20, and is appropriately designed to fit the mounting location of the vehicle on which the vehicle lamp 10 is mounted. As shown in FIG. 1, the plate-like portion 52 is formed at a position facing the receiving portion 22 on the main body 56 of the reflector 50 when the reflector 50 is placed at a predetermined position relative to the housing 20.

As shown in FIG. 3, the size (width) of the plate-shaped portion 52 in the X direction decreases as it moves toward the -Y side. The protruding piece 54 protrudes from the tip 52e of the plate-shaped portion 52 on the -Y side toward the +Z side (one side in the second direction). The main body 56, plate-shaped portion 52, and protruding piece 54 of the reflector 50 are molded integrally with each other. The protruding piece 54 is connected only to the tip 52e of the plate-shaped portion 52 from both ends in the X direction toward the center. The -Y side portion of the plate-shaped portion 52 in the region that substantially overlaps with the protruding piece 54 in the X direction is the opening exposure portion 57. Hereinafter, the regions of the plate-shaped portion 52 that are located on both sides of the opening exposure portion 57 in the X direction and do not overlap with the protruding piece 54 in the X direction are referred to as the left protruding portion 58A and the right protruding portion 58B.

The width of the protruding piece 54 in the X direction is approximately constant in the Z direction and is slightly smaller than the minimum width of the opening 28 of the receiving portion 22 in the X direction. The width of the protruding piece 54 in the X direction may be smaller than the minimum width of the opening 28 in the X direction, but it is preferable that the width is at least half the minimum width of the opening 28 in the X direction so that movement in the X direction (left-right direction) is restricted when the protruding piece 54 is inserted into the opening 28 as described below. The size of the protruding piece 54 in the Z direction is at least larger than the size (i.e., maximum thickness) of the claw portions 24, 25 of the receiving portion 22 in the Z direction.

In the vehicle lamp 10 having the above-mentioned configurations, when the reflector 50 is attached to the housing 20, as shown in FIG. 4, the protruding piece 54 of the plate-shaped portion 52 is positioned at the bottom of the opening 28 of the receiving portion 22, and the left side protruding portion 58A and the right side protruding portion 58B of the plate-shaped portion 52 are positioned behind (below) the claw portions 24, 25 of the receiving portion 22 in the Z direction. This arrangement prevents the reflector 50 from deforming upward from the specified mounting position and from shifting its position in the X direction before components such as the outer lens are attached to the housing 20.

Next, multiple mounting members such as the reflector 50 and the outer lens 110 are attached to the housing 20 (see FIG. 1). When multiple mounting members are attached to the housing 20, as viewed along the C1-C1 line in FIG. 4, the facing portion 112 of the outer lens 110 is disposed on the +Z side of the reflector 50, as shown in FIG. 5. The -Z side surface of the facing portion 112 is provided with a protrusion (contact portion) 114 that protrudes to the -Z side. The protruding piece 54 of the reflector 50 is sandwiched in the Y direction between the receiving portion 22 facing the opening 28 in the housing 20 and the protrusion 114 of the outer lens 110.

As shown in FIG. 6, the protruding piece 54 of the reflector 50 is disposed in the opening 28 in the X direction, and movement in the X direction is restricted by the claws 24 and 25 of the receiving part 22, preventing the position of the reflector 50 from shifting in the X direction. Also, as can be seen by referring to FIG. 4, the left side protruding part 58A and the right side protruding part 58B of the plate-shaped part 52 of the reflector 50 are held down in the opposite direction to the Z direction by the claws 24 and 25 of the receiving part 22 from the front in the Z direction. As shown in FIG. 5, the opening exposed part 57 of the reflector 50 is supported in the Z direction from the rear in the Z direction by the rib 30 of the housing 20. That is, the support part 32 faces the -Z side (the other side in the second direction) of the plate-shaped part 52 of the reflector 50 via the rib 30.

As shown in FIG. 6, when viewed along the Z direction, the +X side 54c of the protruding piece 54 of the reflector 50 and the -X side 24d of the claw portion 24 of the receiving portion 22 of the housing 20 move toward the +X side as they move toward the +Y side. On the other hand, the -X side 54d of the protruding piece 54 and the +X side 25c of the claw portion 25 of the receiving portion 22 move toward the -X side as they move toward the +Y side. Because these surfaces are inclined, the protruding piece 54 is easily guided and positioned in the X direction toward the bottom of the -Y side of the opening 28 between the claw portions 24 and 25. In other words, the sides 24d and 25c of the claw portions 24 and 25 of the receiving portion 22 act as guide surfaces when the protruding piece 54 is inserted into the opening 28.

The housing 20 and the like are made of opaque materials, for example, ASA (Acrylate Styrene Acrylonitrile) resin. The reflector 50 is formed to be able to reflect the light emitted from the light source 40, and is formed, for example, of white methyl methacrylate (PMMA) acrylic resin. At least the light-emitting portion of the outer lens 110 is colorless and transparent to the light emitted from the light source 40, and is formed, for example, of colorless and transparent PMMA acrylic resin. The portion of the outer lens 110 other than the light-emitting portion may be formed integrally with the light-emitting portion, for example, of colorless and transparent PMMA acrylic resin, and then colored with an opaque coloring agent, colorant, etc., or may be two-color molded with the light-emitting portion from opaque PMMA acrylic resin.

The vehicle lamp 10 of the present embodiment described above is a vehicle lamp equipped with a fixing structure for attaching and fixing the reflector 50, which is an attachment member, to the housing 20, which is an attachment receiving member. The vehicle lamp 10 of the present embodiment includes an elongated reflector 50 extending in the X direction, a housing 20 to which the reflector 50 is attached, and a fixing portion 21 and a positioning portion 90 provided on the housing 20. The fixing portion 21 fixes the reflector 50 to the housing 20. The positioning portion 90 positions the reflector 50 at a predetermined position relative to the housing 20. The positioning portion 90 has a receiving portion 22 that receives the reflector 50 in the Z direction, and claw portions 24, 25 formed on the receiving portion 22. The reflector 50 has a main body 56 extending in the X direction, a plate-shaped portion 52 extending from the main body 56 to the housing 20, and a protruding piece 54 provided at the tip of the -Y side of the plate-shaped portion 52. The protruding piece 54 protrudes from the tip of the plate-shaped part 52 to the +Z side of the Z direction that intersects with the X direction. The plate-shaped part 52 of the reflector 50 is engaged with the receiving part 22 in the Z direction. Meanwhile, the protruding piece 54 of the reflector 50 is engaged with at least one of the claw parts 24, 25 in the X direction.

In the vehicle lamp 10 of this embodiment, as shown in FIG. 4, the protruding piece 54 is inserted into the opening 28 between the claws 24, 25 adjacent to each other in the X direction, and the left protruding portion 58A and the right protruding portion 58B of the tip portion 52e of the plate-shaped portion 52 are disposed below the claws 24, 25 of the opening 28 (the other side in the second direction), i.e., on the -Z side, and abut against the claws 24, 25 from the -Z side. This mounting process makes it possible to restrict the upward movement (one side in the second direction) of the plate-shaped portion 52 and the reflector 50 having the plate-shaped portion 52 relative to the housing 20, i.e., to the +Z side. In addition, the protruding piece 54 engages with at least one of the claws 24, 25 adjacent to each other in the X direction, and the movement of the protruding piece 54, the plate-shaped portion 52, and the reflector 50 having them in the X direction can be restricted. According to the vehicle lamp 10 of this embodiment, the movement of the reflector 50 in the +Z direction and in the X direction relative to the housing 20 can be restricted simply by performing a simple mounting process in which the protruding piece 54 is positioned adjacent to at least one of the claws 24, 25, while the tip 52e of the plate-shaped portion 52 is positioned on the -Z side of the claws 24, 25.

In the vehicle lamp 10 of this embodiment, the reflector 50 is fixed to the housing 20 by fastening the fixing portion 21 and the fastening portion 51 using the screws 60A, 60B, and 60, and the movement of the reflector 50 in the circumferential direction with the Y direction as the central axis relative to the housing 20 is restricted. When attaching the reflector 50 to the housing 20, it is necessary to use one point on the outer periphery of the housing 20 and the reflector 50 as a reference based on the positional relationship between the light source 40 of the vehicle lamp 10 and optical components such as various lenses. As described above, since the housing 20 and the reflector 50 are long members in the X direction, there may be cases where the positional deviation between the components, including the housing 20 and the reflector 50, varies at points distant from each other in the X direction from the one point or at points corresponding to the ends.

In addition, it may be difficult or impossible to form an insertion hole or a through hole in the housing 20 and the reflector 50. Therefore, unless some structure is provided to support the attachment of the reflector 50 to the housing 20 at the intermediate position, it is difficult to prevent problems or variations in the attachment between the housing 20 and the reflector 50, or localized detachment from the housing 20 due to the load of the reflector 50 due to its own weight. In the vehicle lamp 10 of this embodiment, even in the area where the fixing portion 21 and the fastening portion 51 are not formed, the receiving portion 22 and the claw portions 24, 25 are formed on the housing 20, and the plate-shaped portion 52 and the protruding piece 54 are formed on the reflector 50, so that even if the housing 20 and the reflector 50 are formed in an elongated shape in the X direction, the positional deviation of the reflector 50 relative to the housing 20 can be suppressed. As a result, the reflector 50 can be stably attached to the housing 20.

In the vehicle lamp 10 of this embodiment, the positioning portion 90 has a pair of claws 24, 25 formed on the receiving portion 22 with a gap P between them in the X direction. The protruding piece 54 of the reflector 50 is located between the pair of claws 24, 25 in the X direction. The size of the protruding piece 54 in the X direction is smaller than the gap P. According to the vehicle lamp 10 of this embodiment, the movement of the protruding piece 54 in the X direction can be restricted by the claws 24, 25. In addition, by simply performing a simple mounting process in which the protruding piece 54 is positioned on the -Y side of the opening 28 between the claws 24, 25 and the tip 52e of the plate-shaped portion 52 is positioned on the -Z side of the claws 24, 25, the movement of the reflector 50 in the +Z direction and in the X direction relative to the housing 20 can be restricted.

In the vehicle lamp 10 of this embodiment, the spacing P in the X direction increases as it moves away from the receiving portion 22, that is, as it moves from the -Y side to the +Y side. In the vehicle lamp 10 of this embodiment, when inserting the protruding piece 54 from the +Y side to the -Y side of the opening 28, the range in the X direction in which the protruding piece 54 is restricted on the +Y side at the beginning of insertion is wider than the range in the X direction in which the protruding piece 54 is restricted on the -Y side at the later stage of insertion. According to the vehicle lamp 10 of this embodiment, the protruding piece 54 can be drawn into the opening 28 from a wide range on the +Y side, and the movement of the protruding piece 54 in the X direction on the -Y side can be restricted within a narrower range than on the +Y side. As a result, even if the opening 28 and the protruding piece 54 are difficult to see when the reflector 50 is attached to the housing 20, the protruding piece 54 can be easily inserted into the -Y side of the opening 28.

As a comparative example, consider a vehicle lamp (not shown) in which the receiving portion 22 of the housing 20 does not have the claw portions 24, 25, and the plate portion 52 of the reflector 50 does not have the left side protrusion portion 58A and the right side protrusion portion 58B.

In the comparative example of the vehicle lamp, in the process of attaching the reflector 50 to the housing 20, the protruding piece 54 of the reflector 50 is abutted from the +Y side against the end face on the +Y side of the receiving portion 22 of the housing 20, and the lower plate surface 52b on the -Z side of the plate-shaped portion 52 is abutted against the upper surface 32a on the +Z side of the support portion 32 (or the end portion on the +Z side of the rib 30). In this case, the outer peripheries of the main body 26 of the housing 20 and the main body 56 of the reflector 50 are fastened together at multiple points with screws 60, and the reflector 50 is attached to the housing 20. At that time, the movement of the plate-shaped portion 52 and the reflector 50 having the plate-shaped portion 52 relative to the housing 20 in the Z direction and the X direction is not restricted. In other words, because the plate-shaped portion 52 and the reflector 50 are not positioned, when the vehicle lamp is subjected to vibrations or when a force is applied that causes the reflector 50 to move in the +Z direction in the Z direction or in the X direction within the lamp chamber of the vehicle lamp, the plate-shaped portion 52 may rotate counterclockwise in a direction that has the Z direction as a tangent, with the base end on the +Y side as the approximate center. When the plate-shaped portion 52 rotates in this way, there is a risk that the tip portion 52e of the plate-shaped portion 52 may jump up toward the +Z side from the specified position at the time of installation.

When the tip 52e of the plate-shaped portion 52 bounces up to the +Z side, the outer lens 110 attached to the +Z side of the reflector 50 is pushed from the -Z side by the tip 52e, and there is a risk that the outer lens 110 will shift from its specified mounting position or come off the housing 20. As described above, in contrast to the comparative vehicle lamp, according to the vehicle lamp 10 of this embodiment, the reflector 50 is positioned relative to the housing 20 at least on the +Z side in the Z direction and in the X direction, so that the outer lens 110 attached to the housing 20 in the lamp chamber on the +Z side of the reflector 50 can be stably positioned in a specified position without being pushed up to the +Z side.

In the vehicle lamp 10 of this embodiment, the positioning portion 90 further has a support portion 32 that supports the lower plate surface (plate surface) 52b of the plate portion 52 of the reflector 50 facing the -Z side in the Z direction. In the vehicle lamp 10 of this embodiment, as shown in FIG. 4, if the protruding piece 54 is inserted into the opening 28 between the claw portions 24, 25 adjacent to each other in the X direction, the plate portion 52 is positioned above the support portion 32, i.e., on the +Z side. This mounting process can restrict the downward movement of the plate portion 52 and the reflector 50 having the plate portion 52 relative to the housing 20, i.e., toward the -Z side. As described above, the protruding piece 54 is engaged between the claw portions 24, 25 adjacent to each other in the X direction, and the plate portion 52 is engaged between the claw portions 24, 25 adjacent to each other in the Z direction and the support portion 32, thereby restricting the movement of the reflector 50 having the plate portion 52 and the protruding piece 54 in the X direction and the Z direction. Furthermore, with the vehicle lamp 10 of this embodiment, the projection 54 is placed in the opening 28 between the claws 24, 25, while the plate-shaped portion 52 is placed on the +Z side of the support portion 32, and this simple installation process strongly restricts movement of the reflector 50 in the Z direction and movement in the X direction relative to the housing 20.

In the vehicle lamp 10 of this embodiment, the support portion 32 includes an upper surface (opposing surface) 32a facing the plate-shaped portion 52, and a rib 30 that bulges from the upper surface 32a toward the lower plate surface 52b of the plate-shaped portion 52 and can abut against the lower plate surface 52b of the plate-shaped portion 52. As a result, as shown in FIG. 5, when the protruding piece 54 is inserted into the opening 28 and the left side protruding portion 58A and the right side protruding portion 58B of the plate-shaped portion 52 are positioned below the claw portions 24, 25 and abut against the claw portions 24, 25 from the -Z side, the rib 30 can abut against the opening exposed portion 57 of the plate-shaped portion 52, and the plate-shaped portion 52 can be supported from the -Z side. The rib 30 bulges from the upper surface 32a of the support portion 32 toward the +Z side and is configured as a curved surface, so that the plate-shaped portion 52 can be supported without applying excessive load to the plate-shaped portion 52.

The vehicle lamp 10 of this embodiment includes an outer lens 110 that can be attached to the housing 20 so as to sandwich the reflector 50 in the Z direction. The outer lens 110 is provided with a protrusion 114 that can be arranged above (on one side in the second direction) the plate-shaped portion 52 that is engaged with the claw portions 24, 25 in the X direction and engaged with the receiving portion 22 in the Z direction. The facing portion 112 of the outer lens 110 can be arranged on the +Z side of the opening exposure portion 57 of the plate-shaped portion 52 between the claw portions 24, 25 in the X direction. The +Z side of the opening exposure portion 57 of the plate-shaped portion 52 is opposite to the -Z side where the opening exposure portion 57 of the plate-shaped portion 52 is supported by the support portion 32, and is the same side as the +Z side where the left side protrusion portion 58A and the right side protrusion portion 58B of the plate-shaped portion 52 are engaged by the claw portions 24, 25. According to the vehicle lamp 10 of this embodiment, at least the movement of the reflector 50 relative to the housing 20 toward the +Z side and in the X direction is restricted, so that the outer lens 110 can be easily and stably attached to a predetermined position on the +Z side of the receiving portion 22 of the housing 20. Also, according to the vehicle lamp 10 of this embodiment, the opening exposed portion 57 of the plate-shaped portion 52 is supported by the support portion 32, and even if a load is applied to the plate-shaped portion 52 toward the +Z side, at least one of the claw portions 24, 25 can prevent the plate-shaped portion 52 from moving toward the +Z side, or the outer lens 110 from shifting in position due to so-called jumping up, as described above.

In addition, the protrusion 114 is provided on the -Z side of the plate surface on the -Z side of the opposing portion 112, on the +Z side of the opening exposed portion 57 and on the +Y side of the protruding piece 54, so that the protruding piece 54 is disposed between the main body 26 of the housing 20 and the protrusion 114 of the outer lens 110 in the Y direction as shown in FIG. 5, and therefore the protruding piece 54 and the reflector 50 equipped with the protruding piece 54 can be positioned in the Y direction as well. Therefore, according to the vehicle lamp 10 of this embodiment, the reflector 50 can be positioned in each of the X direction, Y direction, and Z direction, and the reflector 50 can be fixed to the housing 20.

Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited to the specific embodiment, and various modifications and changes are possible within the scope of the gist of the present invention described in the claims. Furthermore, the components of multiple embodiments can be combined as appropriate.

For example, in the vehicle lamp 10 of this embodiment, as shown in FIG. 1, the receiving portion 22 and the claw portions 24, 25 are disposed between the two fastening fixing portions 21A, 21B in the X direction, but at least one of the receiving portion 22 and the claw portions 24, 25 is provided at a different position in the X direction from the fixing portion 21. For example, multiple fixing portions 21 and at least one of the receiving portion 22 and the claw portions 24, 25 may be disposed sequentially along the X direction from the +X side to the -X side, or multiple fixing portions 21 and at least one of the receiving portion 22 and the claw portions 24, 25 may be disposed sequentially.

For example, the vehicle lamp 10 of this embodiment may have a protruding piece 55 that protrudes from the plate-shaped portion 52 on the opposite side to the protruding piece 54, i.e., on the -Z side, as shown by the dashed line in FIG. 5, and can abut against the rib 30 from the +Z side. The protruding piece 55 may be abuttable against the end of the +Z side of the rib 30 shown by the solid line, and may be formed so as to be able to fit between the rib 30 in the X direction. When the protruding piece 55 can be fitted to the rib 30 from both sides in the X direction, a simple mounting process can be performed to further restrict the movement of the reflector 50 in the X direction relative to the housing 20 by the protruding piece 55 in addition to the claws 24, 25, thereby improving the accuracy of positioning the reflector 50 relative to the housing 20.

For example, in the above embodiment, the claws 24, 25 are connected to the tip of the +Y side of the receiving portion 22 that protrudes from the main body 26 of the housing 20 to the +Y side, but if this does not interfere with installation, they may be connected to the main body 26 and protrude directly from the main body 26 to the +Y side. In that case, the part of the main body 26 to which the tip 52e of the plate-shaped portion 52 and the protruding piece 54 engage, to which the claws 24, 25 are connected, also functions as the receiving portion 22.

In addition, in the above embodiment, two claws 24, 25 are illustrated, but the number of claws provided on the housing 20 may be changed as appropriate to two or more. For example, the housing 20 may further include a pair of claws provided at an interval from each other near the opposite side of the claws 24, 25 in the X direction on the outer periphery of the main body 26, sandwiching the fastening fixing portion 21B. Furthermore, if only one of the two claws 24, 25 can restrict the movement of the protruding piece 54 and the plate-shaped portion 52 in the X direction and position them, the vehicle lamp according to the present invention may include only one claw. Examples of such a case include, for example, a case where an edge portion protruding from the main body 26 of the housing 20 to the +Y side is present on the opposite side of one claw in the X direction across the protruding piece 54, and a case where the protruding piece 54 has a structure that is directly engaged with the receiving portion 22 on the opposite side of the side adjacent to one claw in the X direction.

In the above embodiment, the mounting member and the second mounting member of the vehicle lamp are a reflector and an outer lens, and the mounting member is a housing, but the combination of the members is not limited to these. For example, the mounting member may be an inner lens or various light-guiding members, and the mounting member may be a reflector. In other words, the mounting member and mounting member of the vehicle lamp according to the present invention are not particularly limited as long as they are mounting members that are attached to the mounting member mounted on the vehicle from the +Y side or -Y side along the Y direction (optical axis direction).

In addition, in the above embodiment, a headlight is given as an example of a vehicle lamp according to the present invention, but the vehicle lamp according to the present invention may also be applied to daytime running lights (DRLs), stop lamps, tail lamps, etc.
