2. Description of the Related Art A vehicle configured to mount a light bulb on a reflecting mirror using a set spring in order to position the light source of the light bulb inside the reflecting mirror through a light bulb mounting hole formed on the reflecting mirror made of synthetic resin. Lighting fixtures are known from Japanese Utility Model Application Laid-Open No. 165601/1987.

The reflecting mirror (A) of the automotive lamp described in Japanese Utility Model Laid-Open No. 62-165601 is for supporting the set spring (B) at the rim (1a) of the bulb mounting hole (1). A fastening portion (2) is formed.

A set spring (B) is attached to the engaging portion (2).
A fitting groove (2a) into which the engaging portion (B1) is fitted is formed, and a screw (4) is screwed in the vicinity of the fitting groove (2a).

The screw (4) is screwed onto the engaging portion (2) via a washer (4b) so that the washer (b) covers a part of the fitting groove (2a). Has become.

Therefore, the set spring (B) has its engaging portion (B1) fitted in the fitting groove (2a),
By screwing the screw (4) into the engaging portion (2) via the washer (4b), the screw (4) can be movably attached to the back surface of the reflecting mirror (1).

[0007]

However, in attaching the set spring (B) to the reflecting mirror (A) as described above, the screw (4) must be an essential component for that purpose, and the number of parts is small. As the number of screws increases, there is a problem that the screwing process becomes indispensable and assembly workability is poor.

Therefore, it can be considered that the set spring is locked to the reflecting mirror by a locking means formed integrally with the reflecting mirror.

However, when such a locking means is formed integrally with the reflecting mirror, the locking claws for locking are oriented in a direction substantially orthogonal to the die cutting direction of the reflecting mirror. A slide mold is required to form the pawl, which raises a problem that the cost of the mold increases and the cost of the reflecting mirror increases.

[0010]

In order to solve the above-mentioned problems, the vehicular lamp of the present invention has a claw portion formed on a portion of the reflecting mirror corresponding to the claw portion of the engaging claw of the supporting portion. A hole for die-cutting is formed in the die part.

Therefore, according to the present invention, when the set spring is attached to the reflecting mirror, a separate member such as a screw is not required, it is possible to prevent an increase in the number of parts, and at the time of opening the mold of the lamp body. Since the mold part for forming the claw portion of the stop claw can be pulled out from the hole for mold cutting, the locking claw can be molded integrally with the reflecting mirror without using a slide mold.

Reference numerals 6 and 27 are formed to be separated from each other on the left and right.

The support portion 26 is formed as a block-shaped projection formed in contact with the outside of the left side portion when viewed from the rear of the tubular portion 15. That is, the protrusion is formed with a receiving recess 28 that is open rearward and has a vertically long, substantially rectangular shape. The receiving recess 28 has a tubular portion 15 extending from the center of the opening edge facing the tubular portion 15.
An engaging claw 29 is provided so as to project toward the side, a tip portion of the engaging claw 19 is a claw portion 30, and an engaging groove 30a extending in the vertical direction is formed on the front surface of the claw portion 30. An interval 31a, which is slightly larger than the wire diameter of the main portion 22a of the supported portion 22 of the set spring 21, is provided between the tip end surface 30b of the claw portion 30 and the inner surface of the receiving recess 28 on the cylindrical portion 15 side. There is. The tip surface 30b of the claw portion 30 is inclined so as to move away from the tubular portion 15 as it goes forward.

Further, between the upper and lower edges of the engaging claw 29 and the upper and lower side wall surfaces 28a and 28b of the receiving recess 28, the wire diameter of the arm portions 22b and 22c of the supported portion 22 of the set spring 21 is several times. Intervals 31b and 31c having a size of are formed. The intervals 31a, 31b, 31c are positioned so as to form a substantially "U" shape when viewed from the rear.

Receiving surfaces 32a and 32b are formed on the upper and lower edges of the inner surface of the receiving recess 28 on the side of the tubular portion 15. The receiving surfaces 32a, 32b are inclined so as to move away from the tubular portion 15 as they go forward, and the front end portion thereof is the same as the front end portion of the inner surface of the receiving recess 28 facing the tubular portion side and "V". "They intersect to form a letter.

Further, these receiving surfaces 32a, 32b have a distance 34 between the receiving surface 32a and the tip end surface 30b of the claw portion 30 of the engaging claw 29 when viewed in the vertical direction. The diameter is smaller than the wire diameter of the portion 22a. The inclination of the tip end surface 30b of the claw portion 30 depends on the receiving surface 32.
It is made smaller than the inclination of a and 32b, so that the interval 34 becomes smaller as it goes forward. Therefore, the gap 34 at the front end portion may be sufficiently smaller than the wire diameter of the main portion 22a of the supported portion 22,
The wire diameter at the rear end may be the same as the above wire diameter.

A hole 33 for die cutting reaching the inner surface of the reflecting mirror 13 is formed in a portion of the bottom of the receiving recess 28 corresponding to the front of the claw portion 30 of the engaging claw 29. Then, at least on the upper side of the claw portion 30, there is a sufficient distance between the upper surface of the claw portion 30 and the upper edge of the die-cutting hole 30 when viewed in the front-rear direction, for example, the supported portion 22 of the set spring 21. An interval of 2 to 3 times the wire diameter of the arms 22b and 22c is provided.

The distance from the upper edge of b is larger than the wire diameter of the main portion 22a of the supported portion 22 of the set spring 21. Further, a cutout portion 35 extending substantially in the front-rear direction is formed in a portion of the lower side wall surface 28b facing the inclined surface portion 30c of the claw portion 30.

The hook portion 27 is formed on a part of the cylindrical portion 15. That is, in the portion of the tubular portion 15 located on the opposite side of the portion where the support portion 26 is adjacently formed, the rear end reaches the rear end of the tubular portion 15, and the front end reaches the positioning surface 19 approximately “L”. A notch 36 is formed, and a portion 36a extending in the front-rear direction of the notch 36 serves as an introduction portion, and a portion 36b extending substantially in the vertical direction serves as a locking portion, and a rear edge of the locking portion 36b is formed. An engagement notch 36c is formed.

The set spring 21 is supported by the reflecting mirror 13 as follows.

First, as shown by the alternate long and short dash line in FIG. 7, tilt so that the long side portion 23 is located above the long side portion 24 and the main portion 22a of the supported portion 22 is lowered rearward. In this state, the arm portions 22b and 22c are further left from the main portion 22a (when left and right are referred to in this specification, the left is left and the right is right as viewed in the irradiation direction of the headlight 1). ) The supported portion 22 is set so as to project rearward and the space 31a
Insert it inside. As a result, the gap 31a is reduced to the main portion 2
2a and the arm portions 22b and 22c are formed to have a diameter larger than that of the wire portions. Therefore, as shown by the broken line in FIG. 7 and as shown in FIG. To the front side and reach the front side from the claw portion 30.

From this state, the main portion 22a and the arm portion 2 are moved while moving the corner portion 37a rearward and leftward.
The corner portion 37b intersecting with 2c is moved forward while sliding on the receiving surface 32b. As a result, the corner portion 37b passes through the cutout portion 35 formed in the lower side wall surface 28b, and the portion near the corner portion 37b from the center of the main portion 22a receives the slope portion 30c formed in the claw portion 30. It passes between the upper edge of the surface 32b (see FIG. 9), which causes the corner 37b to
Reaches the front end of the receiving surface 32b, and the other corner 3
7a reaches the front end of the receiving surface 32a. As a result, FIG.
As indicated by the solid line, the position of the set spring 21 is such that the main portion 22a of the supported portion 22 engages with the engagement groove 30a of the claw portion 30 (this position is referred to as the "attachment position"). In this state, the supporting portion 26 of the reflecting mirror 13 is rotatably supported in the front-rear direction. And set spring 2
When removing 1 from the supporting portion 26 of the reflecting mirror 13, each part of the set spring 21 may be moved in the opposite direction to the above mounting.

When the set spring 21 is supported by the reflecting mirror 13 as described above, the front end surface 30b of the claw portion 30 of the engaging claw 29 and the receiving surfaces 32a and 32b when viewed in the vertical direction. Since the space 34 between them is smaller than the wire diameter of the main portion 22a of the supported portion 22 of the set spring 21, the main portion 22a does not slip out of the mounting position. Moreover, the set spring 21
Is longer than the portion located on the upper side (consisting of the arm portion 22b, the long side portion 23 and the hooked portion 25) and lower than the portion disposed on the lower side (consisting of the arm portion 22c and the long side portion 24), and Since it is heavy, its tip end receives a turning force that attempts to move downward, and therefore, the corner portion 37b of the set spring 21 is affected.
Receives a force to move upward and forward, and the corner 37a moves backward and upward. Therefore, the corner 37b does not move in the direction opposite to the moving direction at the time of attachment, and the corner 3
Since 7a collides with the upper side wall surface 28a of the receiving recess 28 and cannot move further, the set spring 21 does not come off from the supporting portion 26 of the reflecting mirror 13.

To attach a light bulb to the reflecting mirror 13,
Do the following:

Reference numeral 38 denotes a light bulb, which is composed of a glass bulb 40 in which a filament 39 is enclosed and which is supported by a base 41.
A positioning flange 42 is formed on the base 41, and a positioning protrusion 43,
43 and 43 are projected.

In the light bulb 38, the glass bulb 40 of the light bulb 38 passes from the rear of the reflection mirror 13 through the light bulb insertion hole 18 and the reflection mirror 1
3, the positioning protrusions 43, 43,
43 is a positioning notch 20 formed on the inner surface of the tubular portion 15,
The positioning flange 42 is brought into contact with the positioning surface 19 of the reflecting mirror 13 by being engaged with 20, 20. Thereby, the light bulb 38 is positioned with respect to the reflecting mirror 13. That is, the positioning flange 42 is brought into contact with the positioning surface 19 to perform positioning in the optical axis direction, and the positioning projections 43, 43, 43 engage with the positioning notches 20, 20, 20 to rotate around the optical axis. The positioning in the direction is performed.

Therefore, the set spring 21 is rotated so that the hooked portion 25 side thereof moves forward. Then, first, the first node 24a of the lower long side portion 24 and the second node 24a
The joint 24c with the joint 24b comes into contact with the rear surface of the positioning flange 42 of the light bulb 38. When the set spring 21 is further rotated from there, the lower long side portion 24 is bent, and the first joint 23a and the second joint 23 of the upper long side portion 23 are bent.
The joint 23c with b contacts the rear surface of the positioning flange 42. From there, the set spring 21 is further rotated to bend the long side portions 23 and 24 together, thereby increasing the force for pressing the positioning flange 42 against the positioning surface 19,
Then, the hooked piece 25b of the hooked portion 25 is moved forward along the introducing portion 36a of the hooking portion 27 of the reflecting mirror 13, and when the hooked piece 25b comes to a position corresponding to the locking portion 36b, the setting is performed. The entire spring 21 is slightly rotated downward to move the hooked piece 25b toward the locking portion 36b,
Therefore, if the force applied to the hooked portion 25 is removed, the set spring 21 tries to return to the original state, whereby the hooked piece 25b moves rearward and the engaging notch 36c is formed.
Engages.

As described above, the light bulb 38 is reflected by the reflecting mirror 13.
Attached to.

When the light bulb 38 is removed from the reflecting mirror 13, the hooked portion 25 of the set spring 21 is pushed forward to move the hooked piece 25b forward from the engaging notch 36c, and the hook is set in that state. Except for the force pressing the hooked portion 25 when the hooked piece 25b reaches the introduction portion 36a by rotating the spring 21 slightly upward, the hooked piece 25b slips backward from the introduction portion 36a. go. Therefore, by rotating the set spring 21 so as not to be positioned behind the positioning flange 42 of the light bulb 38, the light bulb 38 can be taken out rearward from the light bulb mounting hole 16.

In the above-described headlight 1, the supporting portion 26 that supports the set spring 21 has a die-cutting portion at a position corresponding to the front of the claw portion 30 that locks the supported portion 22 of the set spring 21. A hole 33 for use is formed. Thereby, the claw portion 30 can be integrally molded with the reflecting mirror 13 without using a slide mold. That is, when the reflecting mirror 13 is molded, since the mold cutting direction is the front-back direction, a slide mold is usually required to form a portion having a so-called undercut portion such as the claw portion 30, This is because in the headlight 1 described above, the mold portion required for forming the claw portion 30 can be pulled out forward from the die-cutting hole 33. Further, the hole 33 can also serve as a heat dissipation hole for discharging the air in the reflecting mirror 13 warmed by the lighting of the light bulb 38 to the outside.

Also, as shown in the above embodiment, the set spring 21 can be supported by the support portion 26 by changing its posture in a fixed order, so that the reflecting mirror of the set spring 21 can be supported. It is not necessary to bend a part of the set spring 21 or a part of the support portion 26, for example, the claw portion 30, when attaching to the mirror 13, and a material having no elasticity, such as FRP, is used as the molding material of the reflecting mirror 13. In addition, the set spring 21 does not need to have a long-span portion that requires bending.

12 to 14 show a second embodiment of the vehicular lamp of the present invention. The second embodiment is different from the above-described first embodiment only in the hooked portion of the set spring and the hooked portion of the reflecting mirror, and the other portions are the same as those in the first embodiment. Since it is the same as the above, only the different part will be described in detail.

The set spring 21A is different from the set spring 21 in the first embodiment in the shape of the hooked portion.

The hooked portion 25A is integrally connected to the tip of the upper long side portion 23, and is connected to the base 44 having a substantially inverted "U" shape when viewed from the rear and the tip of the base 44. And a hook portion 45. One end of the base 44 on the upper side is the long side 2
3, the lower end is folded back to the supported portion 22 side, the hook portion 45 has a substantially hook shape, and the longer end portion extends forward from the base portion 44. Is connected to the other end of the base 44, and the shorter end, that is, the engaging end 45a is folded back.

The hook portion 27A has an insertion hole 46 formed by penetrating the cylindrical portion 15 of the reflecting mirror 13 in the front-rear direction and a front opening edge of the insertion hole 46 in the circumferential direction of the cylindrical portion 15, which is substantially omitted in this embodiment. On the lower side, a hooking hole 47 formed adjacently is formed.

Therefore, as described in the first embodiment, while pressing the positioning flange 42 of the light bulb 38 against the positioning surface 19 of the reflecting mirror 13 by the long side portions 23 and 24, the long side portion 23, especially the long side portion 23, is pressed. The hook portion 45 is inserted from the rear into the insertion hole 46 while bending the second joint 23b. Then, when the engaging end 45a exceeds the front end of the insertion hole 46, the set spring 21A is rotated slightly downward so that the engaging end 45a faces the hooking hole 47.
Then, when the force that bends the set spring 21A is released, the long side portion 23 tries to return to its original state, whereby the hooked portion 25A moves rearward, and the engaging end 45a moves to the hooking hole 4.
7 is engaged. In this way, the light bulb 38 becomes
Attached to.

When the light bulb 38 is detached from the reflecting mirror 13, the hooked portion 25A of the set spring 21A is pushed forward to move its engaging end 45a forward from the hook hole 47, and in that state, the set spring 21A is rotated slightly upward so that the hook portion 45 comes to the position where the insertion hole 46 is seen, and then the hook portion 45 moves the insertion hole 46 rearward except for the force pressing the hooked portion 25A. Come out. Therefore, set the spring 21A to the light bulb 38
The electric bulb 38 can be taken out rearward from the electric bulb mounting hole 16 by rotating the positioning flange 42 so as not to be positioned behind the electric bulb 38.

As described above, the set spring 2
When pushing the front end portion of 1A forward, for example, applying a finger to the base portion 44 of the hooked portion 25A makes it easy to apply force.

Further, in the second embodiment, the hook portion 27A is formed adjacent to the insertion hole 46 formed by penetrating the cylindrical portion 15 in the front-rear direction and the front opening edge of the insertion hole 46. And the hooking hole 47, the slide die is not required to form the hooking portion 27A.
