The left and right extending portions of the first extension 2 are formed in a substantially U-shaped cross section with a bent portion 2a projecting forward, and the front surface is a design portion (design surface) designed for decoration. Yes.

  The first extension 2 is formed with a through hole 23 penetrating substantially along the front-rear direction in the upper part of the bent portion 2a. The through hole 23 communicates the front and rear of the first extension 2. ing. As will be described later, the through hole 23 is formed to have a predetermined vertical width so that the extending portion 32 of the second extension 3 can move (bend) in the vertical direction within the through hole 23. . In the first extension 2, the lower part of the through hole 23 (the part facing the lower end of the through hole 23) is a hook engaging part 21 that protrudes slightly upward, and the hook of the second extension 3 to be described later. The portion 321 is engaged. Further, a screw hole 25 along the front-rear direction is formed in the lower part of the bent portion 2a on the rear surface of the first extension 2.

  The second extension 3 is for partially decorating the periphery of the light emitting part of the vehicular lamp 1, and the first extension 2 covers the upper half of the front surface of the left and right extension part of the first extension 2. Is attached from the front. The second extension 3 has a main body portion 31 formed in a shape extending in the left-right direction, and the front surface of the main body portion 31 is a design portion (design surface) designed for decoration. Yes. The main body 31 is formed in a shape that slopes backward and upward along the upper half of the first extension 2, and the rear end 311 is a forward opening 24 formed at the upper end of the first extension 2.

In the second extension 3, an extension portion 32 formed in a shape extending rearward is projected from the rear surface of the lower end portion of the main body portion 31. The extending portion 32 has flexibility in the vertical direction, and is elastically bent in the vertical direction around the base end portion (front end portion).
Further, the extending portion 32 is bent at substantially the center in the front-rear direction, and a substantially half portion on the front end side (rear side) than the bent portion is an inclined portion 322 that is inclined downward toward the rear. ing. On the other hand, in the extending portion 32, a substantially half portion on the base end side (front side) with respect to the bent portion has a concave portion 3a that opens downward in the most proximal portion, and the tip end is more distal than the concave portion 3a. The side portion is a hook portion 321. The hook portion 321 is in a state in which the extension portion 32 is bent downward while being inserted from the front through the through hole 23 of the first extension 2, so that the jaw of the hook portion 321 is in the state of the first extension 2. The hook engaging portion 21 is engaged with the hook engaging portion 21 from above so as to be locked to the rear surface of the hook engaging portion 21.

The reflector 4 has a non-exposed portion 41 that is disposed behind the left and right extending portions of the first extension 2 and is not exposed to the front, and is attached to the first extension 2 by the non-exposed portion 41. The non-exposed portion 41 is formed in a substantially flat plate shape substantially orthogonal to the front-rear direction, and has an insertion hole 411 penetrating in the front-rear direction. Then, with the front surface of the non-exposed portion 41 in contact with the rear surface of the first extension 2 (the top surface of the boss portion in which the screw hole 25 is formed), the screw N inserted through the insertion hole 411 from the rear is the first. The reflector 4 and the first extension 2 are fastened and fixed by being screwed into the screw hole 25 of the one extension 2.

Next, a procedure for fixing the first extension 2, the second extension 3, and the reflector 4 will be described with reference to FIGS.
2-4 is a figure for demonstrating each state when attaching the 2nd extension 3 to the 1st extension 2, FIG. 5 shows the 1st extension 2 of the state to which the 2nd extension 3 was attached. It is a figure for demonstrating a state when attaching the reflector.

First, the second extension 3 is attached to the first extension 2.
Here, as shown in FIG. 2, the assembling worker moves the second extension 3 from a position slightly above the first extension 2 as shown in FIG. The second extension 3 is attached to the first extension 2 from the front so that 32 is inserted through the through hole 23 of the first extension 2 from the front.

  At this time, the second extension 3 only needs to be inserted into the through hole 23 of the first extension 2 in the second extension 3. At this time, the hook portion 321 of the extension 32 is engaged with the hook of the first extension 2. It does not have to be engaged with the portion 21 yet. Therefore, the assembly operator extends the extended portion 32 of the second extension 3 in the state where the extended portion 32 is spaced upward from the design portion 22 in front of the hook engaging portion 21 in the design surface of the front surface of the first extension 2. The second extension 3 can be attached to the first extension 2 while the portion 32 is inserted through the through hole 23. Therefore, the extension part 32 can be prevented from coming into contact with the design part 22 in the process of attaching the second extension 3 to the first extension 2.

  Then, as shown in FIG. 4, the second extension 3 is attached to the first extension 2 by fitting the rear end 311 of the second extension 3 into the opening 24 of the first extension 2. . In this attached state, the extension 32 of the second extension 3 is exposed to the rear of the first extension 2 through the through hole 23 of the first extension 2.

Next, the reflector 4 is fixed to the first extension 2.
Here, as shown in FIG. 5, the assembly operator presses the inclined portion 322 at the tip of the extension portion 32 of the second extension 3 exposed to the rear of the first extension 2 with the protruding portion 412 of the reflector 4. Thus, the reflector 4 is attached from the rear of the first extension 2. Then, a downward force acts on the extending portion 32 of the second extension 3 by pressing the inclined portion 322 inclined downward toward the rear from the rear. As a result, the second extension 3 receives a downward force from the extension portion 32 in a state where the rear end portion 311 of the main body portion 31 is locked to the opening portion 24 of the first extension 2. The portion 32 bends downward from its proximal end. As a result, as shown in FIG. 1, the hook portion 321 of the second extension 3 engages with the hook engaging portion 21 of the first extension 2 from above, and the first extension 2 and the second extension 3 are fixed to each other. The

Then, the reflector 4 is fastened and fixed to the first extension 2 by screwing the screw N inserted through the insertion hole 411 of the reflector 4 into the screw hole 25 of the first extension 2. Further, as a result, the second extension 3 is held in a state in which the extending portion 32 is bent downward and the hook portion 321 is engaged with the hook engaging portion 21, and as a result, is fixed to the first extension 2. Retained.
Thus, the first extension 2, the second extension 3, and the reflector 4 are fixed to each other.

As described above, according to the present embodiment, the extending portion 32 of the second extension 3 is separated from the design portion 22 of the first extension 2 upward with the extending portion 32 of the first extension 2. After the second extension 3 is attached to the first extension 2 from the front while being inserted through the through hole 23 from the front, the extension 32 exposed to the rear of the first extension 2 through the through hole 23 is the non-exposed portion 41 of the reflector 4. By attaching the reflector 4 to the first extension 2 from behind while pressing from the rear with the (projecting part 412) and bending downward, the hook part 321 of the second extension 3 engages with the hook of the first extension 2. Engage with the part 21. That is, by using the reflector 4 disposed behind the first extension 2, the second extension 3 is attached to the first extension 2 without contacting the design portion 22 of the first extension 2. The first extension 2 and the second extension 3 can be fixed by engaging the hook portion 321 of the extension 3 with the hook engaging portion 21 of the first extension 2.
Therefore, the two design parts of the first extension 2 and the second extension 3 can be fixed without impairing the appearance quality.

  In addition, since the first extension 2, the second extension 3 and the reflector 4 are fixed to each other with the same fixing structure as in the prior art, for example, no special process such as “thermal caulking” or “bending” is required, so that the manufacturing cost is reduced. Can be suppressed to the same level as in the past.

  The embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.

For example, in the above-described embodiment, an example in which the design component fixing structure according to the present invention is applied to a vehicular lamp has been described. However, the present invention is not limited as long as two design components each having a design portion are fixed to each other. The present invention is not limited to the vehicular lamp and can be widely applied.
Further, even when the present invention is applied to a vehicular lamp, the first unique design part and the second design part according to the present invention are not limited to the extension, and similarly, the non-exposed part according to the present invention is not limited to the reflector. .

  In addition, the hook portion 321 of the second extension 3 is engaged with the hook engaging portion 21 of the first extension 2 from above, but this engagement direction is from one side of the orthogonal direction substantially orthogonal to the front-rear direction. If so, it may be from the lower side, from the left side or the right side. However, in this case, the extending portion 32 of the second extension 3 is flexible in the orthogonal direction, and the through hole 23 of the first extension 2 is connected to the hook engaging portion 21 in the orthogonal direction. It is necessary to form on one side. In this case, when the second extension 3 is attached to the first extension 2, the extending portion 32 of the second extension 3 is separated from the design portion 22 of the first extension 2 to one side in the orthogonal direction. Of course.

  Further, the extended portion 32 of the second extension 3 is bent downward by the inclined portion 322 at the tip thereof being pressed from the rear by the projecting portion 412 of the reflector 4, but the reflector 4 is not exposed. The inclined portion 322 may not be provided as long as the portion 41 is pressed from the rear and bent downward. Similarly, the non-exposed portion 41 of the reflector 4 may not have the protruding portion 412 as long as the extension portion 32 of the second extension 3 is bent downward when attached from the rear.

Moreover, if the reflector 4 has the non-exposed part 41 arrange | positioned at the back of the 1st extension 2, parts other than the said non-exposed part 41 may be exposed ahead.
