[0016] In addition, in the drawings shown below, an XYZ Cartesian coordinate system is set up, with the X-axis direction representing the front-to-rear direction (length direction) of the vehicle lighting fixture 1, the Y-axis direction representing the left-to-right direction (width direction) of the vehicle lighting fixture 1, and the Z-axis direction representing the up-to-down direction (height direction) of the vehicle lighting fixture 1.

[0017] The vehicle lamp 1 of this embodiment is an application of the present invention to a rear combination lamp mounted, for example, at both corners on the rear end of a vehicle (not shown) (in this embodiment, the corner on the left rear end).

[0018] As shown in Figure 1, the vehicle lamp 1 of this embodiment has a structure in which a bracket 4 fixed to the housing 2 and a lamp unit (not shown) fixed to the housing 2 via this bracket 4 are arranged inside a lamp body 3 composed of a housing 2 that is open on the front side and an outer lens (not shown) that covers the opening of the housing 2.

[0019] The vehicle lamp 1 of this embodiment has a structure in which components that make up the lamp unit, such as a lamp (light source), inner lens (light guide), reflector, and extension, are arranged inside the lamp body 3, and these components are attached to the inside of the lamp body 3 together with a bracket.

[0020] Incidentally, the lamp body 3 has an outer lens that is inclined or curved from the inside to the outside in the vehicle width direction to match the slant shape given to the corner portion on the rear end side of the vehicle.

[0021] In this case, the space on the outside in the vehicle width direction between the housing 2 and the outer lens is narrower than the space on the inside. For this reason, the present invention is preferably used in a mounting structure in which the bracket 4, which is one of the components, is mounted to a side surface (one face) of the housing 2, which is one of the components, from the rear (one side) to the front (other side) in the fore-and-aft direction (one direction) of the vehicle along this side surface in the narrow space located on the outside in the vehicle width direction.

[0022] Specifically, in the mounting structure of this embodiment to which the present invention is applied, the housing 2 has an engaged portion 21 and a locked portion 22 at a position opposite one end side of the bracket 4 along the fore-and-aft direction of the vehicle, as shown in Figures 7 and 8.

[0023] On the other hand, as shown in Figures 9, 10 and 11, the bracket 4 has, at one end side (hereinafter referred to as the tip side of the bracket 4) along the fore-and-aft direction of the vehicle, an engaging portion 41 that engages with the engaged portion 21 and a locking portion 42 that locks with the locked portion 22.

[0024] The engaged portion 21 has a first abutment surface 21a and a second abutment surface 21b. On the other hand, the engaging portion 41 has a first abutment surface 41a that abuts against the first abutment surface 21a and a second abutment surface 41b that abuts against the second abutment surface 21b when engaged with the engaged portion 21.

[0025] In this embodiment, the engaged portion 21 is configured as a recess (hereinafter referred to as recess 21) recessed toward the front side in the longitudinal direction of the vehicle, as shown in Fig. 8. On the other hand, the engaging portion 41 is configured as a protrusion (hereinafter referred to as protrusion 41) protruding toward the front side in the longitudinal direction of the vehicle, as shown in Fig. 10.

[0026] 10, a pair of first contact surfaces 41a are provided on both sides in the width direction (the vertical direction of the vehicle in this embodiment) sandwiching the front-rear direction of the protrusion 41. On the other hand, a pair of first contacted surfaces 21a are provided on both sides in the width direction of the inner surface of the recess 21, as shown in FIG.

[0027] 10, the second contact surface 41b is formed by the tip surfaces of a pair of rib walls 41c that protrude parallel to each other from the surface of the protrusion 41 that faces the side surface of the housing 2. On the other hand, the second contacted surface 21b is formed by the surface that faces the pair of rib walls 41c on the inner surface of the recess 21, as shown in FIG.

[0028] Furthermore, the surface of the protrusion 41 opposite to the surface on which the pair of rib walls 41c are provided is a flat third abutment surface 41d. On the other hand, the inner surface of the recess 21 is provided with a third abutted surface 21c that abuts against the third abutment surface 41d.

[0029] The locking portion 42 has an elastic piece 43 that protrudes forward in the longitudinal direction of the vehicle, and a claw portion 42a that protrudes from the tip of the elastic piece 43 toward the locked portion 22 side.

[0030] 10 and 11, the elastic piece 43 is located on the opposite side of the protrusion 41 from the side facing the side surface of the housing 2, and is arranged in parallel with the protrusion 41. In this embodiment, the elastic piece 43 has a pair of elastic displacement portions 43a that protrude forward in the longitudinal direction of the vehicle, and a connecting portion 43b that connects the tips of these elastic displacement portions 43a, and is arranged to be elastically displaceable (flexibly deformable) from the side facing the side surface of the housing 2. Furthermore, an opening 43c that faces the protrusion 41 is formed on the inside of the elastic piece 43.

[0031] The shape of the elastic piece 43 is not necessarily limited to this, and can be changed as appropriate. The shapes of the first contact surface 41a and the second contact surface 41b provided on the protrusion (engagement portion) 41 can also be changed as appropriate.

[0032] As shown in FIG. 10, the claw portion 42a protrudes from the surface of the connecting portion 43b located on the tip side of the elastic piece 43, which surface faces the locked portion 22.

[0033] In this embodiment, as shown in Figure 8, the engaging portion 22 is located further forward in the fore-and-aft direction of the vehicle than the recess (engaged portion) 21 and is composed of a claw portion (hereinafter referred to as claw portion 22) that protrudes toward the side opposite the elastic piece 43.

[0034] In this embodiment, the claw portion 42a of the locking portion 42 is configured to be locked to a claw portion that becomes the locked portion 22, but it is also possible to configure the claw portion 42a of the locking portion 42 to be locked to a recess or hole that becomes the locked portion 22. Also, a configuration in which a plurality of locked portions 22 and locking portions 42 are provided may be used.

[0035] 1 to 6, in the mounting structure of this embodiment having the above configuration, bracket 4 is slid from the rear to the front in the longitudinal direction of the vehicle along the side surface of housing 2. As a result, protrusion (engaging portion) 41 located on the tip side of bracket 4 is inserted into and engaged with recess 21 (engaged portion) 21 located on the side surface of housing 2.

[0036] Furthermore, while the elastic piece 43 is elastically displaced (flexibly deformed) toward the side opposite to the side facing the side surface of the housing 2, the claw portion 42a located on the tip side of the elastic piece 43 climbs over the claw portion (locked portion) 22 on the housing 2 side. As a result, the claw portion 42a (locking portion 42) on the bracket 4 side is locked to the claw portion (locked portion) 22 on the housing 2 side.

[0037] As described above, in the mounting structure of this embodiment, the tip end side of the bracket 4 can be positioned and restricted relative to the side surface of the housing 2 in the front-rear direction of the vehicle.

[0038] Furthermore, in the mounting structure of this embodiment, when the protrusion (engaging portion) 41 is engaged with the inside of the recess 21 (engaged portion) 21 described above, the pair of first abutment surfaces 41a abut against the pair of first abutment surfaces 21a on the inner surface of the recess 21, thereby making it possible to position and regulate the tip side of the bracket 4 in the vertical direction of the vehicle relative to the side of the housing 2.

[0039] Furthermore, in the mounting structure of this embodiment, when the protrusion (engaging portion) 41 is engaged with the inside of the above-mentioned recess 21 (engaged portion) 21, the second abutment surface 41b abuts against the second abutment surface 21b on the inner surface of the recess 21, and the third abutment surface 41d abuts against the third abutment surface 21c on the inner surface of the recess 21, making it possible to position and restrict the tip side of the bracket 4 in the left-right direction of the vehicle relative to the side of the housing 2.

[0040] As described above, the mounting structure of this embodiment makes it possible to properly position and mount the tip side of the bracket 4 relative to the side of the housing 2 in a narrow space located on the outside in the vehicle width direction, without using a mounting structure such as screw fastening.

[0041] In the mounting structure of this embodiment, the housing 2 has a hole 23 at a position facing the other end of the bracket 4 along the front-to-rear direction of the vehicle (hereinafter referred to as the rear end of the bracket 4), as shown in Fig. 7. Meanwhile, the bracket 4 has a boss 44 and a screw hole 45 formed in the boss 44 at the other end along the front-to-rear direction of the vehicle, as shown in Fig. 9.

[0042] In the mounting structure of this embodiment having the above-described configuration, after the tip side of the bracket 4 is attached to the side surface of the housing 2, a screw (not shown) is threaded into the screw hole 45 through the hole 23 from the rear side of the housing 2. This fixes the rear end side of the bracket 4 to the front side of the housing 2, making it possible to mount the bracket 4 to the front side of the housing 2.

[0043] As described above, the vehicle lamp 1 of this embodiment is provided with the mounting structure to which the present invention is applied, and thus it is possible to mount the bracket 4 in a narrow space located on the outside in the vehicle width direction by appropriately positioning it relative to the side surface of the housing 2. It is also possible to improve the efficiency of the work when mounting the bracket 4 to the housing 2.

[0044] The present invention is not necessarily limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the above embodiment illustrates an example of the application of the present invention to an attachment structure in which one component, the housing 2, is attached to the other component, the bracket 4, but the present invention can also be applied when attaching a component other than the bracket 4 to the housing 2.

[0045] In other words, with regard to the mounting structure to which the present invention is applied, the present invention can be widely applied to a structure in which a component is attached to one surface of at least one of the components comprising the housing 2, bracket 4, and components constituting the lighting unit, from one side to the other in one direction along the surface.

[0046] In particular, the mounting structure to which the present invention is applied can be suitably used when mounting one member to another member in the narrow space described above.

[0047] Furthermore, in the above embodiment, an example was given of the application of the present invention to a rear-side vehicle lamp such as the above-mentioned rear combination lamp, but the vehicle lamp to which the present invention can be applied is not limited to the above-mentioned rear-side, and the present invention can also be applied to a front-side vehicle lamp such as a front combination lamp (headlamp), for example.
