JP 2010-254257

  However, the above-described prior art is configured as a so-called direct-type lamp in which light emitted from the LED in the lamp chamber is directly distributed in front of the lamp body, and the light emitted from the LED has directivity. For this reason, on the road surface illuminated by the lamp main body, there is a problem that a place along the irradiation axis of the LED is particularly bright, that is, so-called spotlight is generated, and the illuminated road surface is difficult to visually recognize.

  Moreover, in order to illuminate the road surface uniformly, the number of LEDs may be increased. However, the number of parts increases, the structure becomes complicated, the number of assembling steps increases, and the cost increases.

  The present invention has been made in view of the above-described problems of the prior art, and an object thereof is to provide a vehicular illumination device that can uniformly illuminate a foot without increasing the number of components of a lamp body.

In order to solve the above-mentioned problem, in the vehicle lighting device according to claim 1, a light emitting element as a plurality of light sources and light emission of each light emitting element are predetermined in a lamp chamber defined by a translucent case and a housing. A vehicle lighting device for foot lighting that includes a lamp body in which a reflector that reflects and distributes light in a direction is disposed,
The reflector is integrally formed with the housing, and a printed wiring board on which the light emitting element is mounted is fixed.

  (Operation) In the form in which the lighting device is assembled to the vehicle body, the light emitting elements and the reflectors corresponding to the respective light emitting elements are arranged in a line along the opening of the door of the automobile, and the light distribution of the lamp body is the opening of the door. However, the light emitted from the multiple light emitting elements is reflected by each reflector and is distributed in a predetermined direction (outside in the vehicle width direction) as a substantially parallel light. A wide area at the foot (road surface) is illuminated uniformly.

  Since the reflector is integrally formed with the housing, the number of parts constituting the lamp body is small.

  According to a second aspect of the present invention, in the vehicular lighting device according to the first aspect, a plate-like spacer that is in close contact with the printed wiring board and the housing is interposed, and the light emitting element is disposed on the spacer. A shade is provided that shields light that exits from the reflector and travels to other than the effective reflecting surface of the reflector.

  (Function) Since most of the light emitted from the translucent case (light distribution of the lamp body) is light distribution-controlled by the effective reflecting surface of the reflector, a wide area at the foot of a person getting on and off the car ( The road surface is more evenly illuminated.

  In Claim 3, In the vehicle lighting device according to Claim 1 or 2, the lamp body is attached to a lower part of a vehicle body side surface (an outdoor part such as a rocker panel or a side sill disposed on the vehicle body). It is supported on a bezel having a space through which light emitted from the translucent case can pass (a cosmetic rimming member called “Bezel”, hereinafter referred to as a bezel), and its optical axis is outside in the vehicle width direction. It was arranged so as to incline downward with respect to the horizontal line facing.

  (Operation) The light axis of the lamp body is inclined downward with respect to the horizontal line facing the outside in the vehicle width direction, so that the light emitted from the translucent case (light distribution of the lamp body) is guided to a region far from the vehicle. However, since the light emitted from the translucent case passes through the space portion of the bezel, the light component traveling upward from the horizontal in the light emitted from the translucent case is shielded.

According to a fourth aspect of the present invention, in the vehicle lighting device according to any one of the first to third aspects, the space portion of the bezel is defined by a frame-type extending portion that extends rearward with respect to the front surface of the sevel. And
The lamp body is engaged with an uneven lance from the back side of the bracket to a frame type bracket disposed so as to cover at least a part of the frame type extension part from the back side, and the bracket is mounted on the lower side of the vehicle body. It was comprised so that it might be hold | maintained at the form pressed by the said frame type extension part.

  (Operation) The optical axis of the lamp body tilts downward with respect to the horizontal line facing the outside in the vehicle width direction, so that the lamp body (translucent case) can be seen from the side or rear of the vehicle through the space of the bezel. Although the light exit surface may be directly visible, the frame-type extension of the bezel is placed in the lamp body (translucent body) so that the light exit surface of the translucent case is located at a predetermined position in the space of the bezel. Since the light case is supported, the light exit surface of the lamp body (translucent case) is not directly visible from the side or rear of the vehicle. In particular, when the space of the bezel is configured by an opening that opens to the front side of the bezel, as shown in FIGS. 3 and 4, the lowermost part P1 of the light emitting surface of the translucent case is the front surface of the bezel. By configuring so that the position is higher than the uppermost portion P2 of the opening, the light emission surface of the lamp body (translucent case) is not directly visually recognized from the side or the rear of the vehicle.

  In addition, the structure that supports the lamp body at a deep position in the space of the bezel is a cantilever support structure that supports the lamp body by the frame-type extension of the bezel, so the durability of the lamp body support structure There is a concern that the lamp body will vibrate due to the vibration caused by driving the engine, the light distribution of the lighting device will be blurred, and the visibility of the road surface will be reduced.

  However, in claim 4, the frame-type bracket fixed to the lower side of the vehicle body also supports the lamp body, that is, the frame-type bracket that covers the frame-type extension of the bezel cooperates with the frame-type extension of the bezel. Since it works and supports the lamp body, it has excellent strength (rigidity and durability) as the lamp body support structure, and the lamp body shakes due to vibrations caused by driving the engine and the light distribution of the lighting device is blurred. Does not occur.

  In order to integrate the lamp body into the frame-type bracket, the projection on the lamp body (translucent case) side becomes the frame-type bracket by engaging and pushing the lamp body from the back side of the frame-type bracket. Since the concavo-convex lance is engaged with the concave portion on the side, the lamp body can be easily integrated with the frame bracket.

  In addition, although the shape of the lower part of the side of the vehicle body differs depending on the vehicle type, by preparing a bezel and bracket corresponding to each vehicle type, the lamp body of the vehicle lighting device can be shared and attached to the vehicle body of different vehicle types it can.

  According to a fifth aspect of the present invention, in the vehicle lighting device according to the fourth aspect, the lamp body is configured to include a portion that is fastened to the frame-type extension portion of the bezel and the frame-type bracket. .

  (Operation) The lamp body slides along the pressing surface of the bezel with the frame-shaped extension by vibration accompanying the driving of the engine only when the lamp body is pressed and held by the frame-type extension of the bezel. Although there is a risk of vibration, the lamp body is fastened together with the frame-type bracket (the part covering the back side of the frame-type extension part of the bezel) together with the frame-type extension part of the bezel. The relative displacement (vibration) of the bezel of the main body with respect to the frame-type extension portion is reliably suppressed.

  That is, in addition to the frame-type bracket that covers the frame-type extension part of the bezel supporting the lamp body in cooperation with the frame-type extension part of the bezel, the lamp body is attached to the frame of the bezel together with the frame-type bracket. By tightening together with the mold extension, the strength (rigidity, durability) as the support structure of the lamp body becomes even better, and the lamp body vibrates due to vibration accompanying the drive of the engine and the lighting device The problem that the light distribution is blurred does not occur reliably.

  As is clear from the above description, according to the vehicular illumination device of the present invention, since a wide area (road surface) at the foot of a person getting on and off the automobile is illuminated uniformly, the flashing of the road surface is suppressed. The visibility of the feet when getting on and off is improved.

  Since the number of parts composing the lamp body is small, the configuration of the lighting device becomes simpler and more compact.

  That is, a vehicle illumination device for foot illumination that can uniformly illuminate a wide area (road surface) of the foot without complicating the configuration of the lamp body is provided.

  According to the second aspect, since a wide area (road surface) of the foot of a person getting on and off the vehicle is illuminated more uniformly, the visibility of the foot when getting on and off is further improved.

  According to the third aspect, since the light distribution of the lamp body is guided to a region far from the vehicle, it is possible to uniformly illuminate a wide range of road surfaces, and when the light distribution of the lamp body passes through the space of the bezel. Since the light component going upward from the horizontal is shielded, the following vehicle or the like does not have the illusion that the lighting device for the foot illumination is turned on as the backup lamp is turned on.

  According to the fourth aspect, the light emitting surface of the translucent case becomes a deep position in the space portion of the bezel, and the light emitting surface of the lamp body (translucent case) is directly from the side or rear of the vehicle. Since it is not visually recognized, it is not certain that the following vehicle or the like has an illusion that the lighting of the foot lighting device is lit as the backup lamp.

  In addition, the frame-type extension of the bezel and the frame-type bracket cooperate to support the lamp body, so the strength of the lamp body as a support structure is excellent, and the lighting at the foot is blurred and visible Will not drop.

  Moreover, since the lamp body can be made common even if the vehicle types are different, the vehicular illumination device can be provided at a lower cost.

  According to the fifth aspect, the strength as the support structure of the lamp body is further improved, and there is no possibility that the visibility of the foot will be lowered due to the illumination at the foot.

It is a principal part expansion perspective view of a bracket.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples of lighting devices for foot lighting according to the present invention.

  In FIG. 1 to FIG. 6 showing the first embodiment of the lighting device for foot illumination, the lighting device 10 is disposed on the lamp body 11 that forms a predetermined light distribution, and the vehicle body side lower portion (below the door). The bezel 30 that is assembled to the rocker panel 2 and supports the lamp body 11 and the bracket 40 that is also assembled to the rocker panel 2 and holds the lamp body 11 against the bezel 30 are mainly configured. Has been.

  The lamp body 11 is formed in a rectangular shape that is long on the left and right (left and right when the lamp body is viewed from the front), and has a long and thin box-shaped translucent case 14 that is open on the back side, and is integrally welded to the back side of the case 14. And a printed wiring board 23 in which light emitting elements (hereinafter referred to as LEDs) 24 that are a plurality of light sources are mounted in a line at equal intervals; A reflector unit 21 in which a plurality of reflectors 22 are linearly integrated is arranged. 2-4, the code | symbol 22a shows the effective reflection surface of the reflector 22, and the code | symbol 22b shows the connection part between the adjacent effective reflection surfaces 22a and 22a.

  The housing 12 has a structure in which a reflector unit 21 is integrally formed on the front side thereof, and a printed wiring board 23 on which an LED 24 is mounted is fixed to a stepped portion 12a of the housing 12 by a tapping screw 25 via a plate-like spacer 16. Has been.

  The plate-like spacer 16 that is in close contact with the printed wiring board 23 and the housing 12 (the stepped portion 12a thereof) is provided with a shade 17 that shields light that is emitted from the LED 24 and goes to the area other than the effective reflection surface 22a of the reflector 22. Yes.

  As shown in FIGS. 3 and 4, the lamp body 11 is assembled to the rocker panel 2 and constitutes a main part of the lighting device 10 that illuminates the road surface of a person who opens and closes the door and gets on and off the automobile. However, since the light emitted from the LED 24 is reflected by each reflector 22 (its effective reflection surface 22a) and is distributed as a substantially parallel light in a predetermined direction (outside in the vehicle width direction), it is configured as a reflective lamp. A wide area (road surface) under the feet of people getting on and off can be evenly illuminated.

  In particular, since most of the light emitted from the translucent case 14 (the light distribution of the lamp body 11) is controlled by the effective reflection surface 22a of the reflector 22, a wide area at the foot of a person getting on and off the automobile. (Road surface) can be illuminated more uniformly.

  Next, a structure for attaching the lamp body 11 to the rocker panel 2 will be described.

  As shown in FIGS. 3 and 4, the rocker panel 2, which is an outside part, has a transverse section that curves from the side surface of the vehicle body to the bottom surface, and the curved region of the rocker panel 2 includes a front and rear along the side surface of the vehicle body. An extended rectangular opening 3 for engaging the bezel is provided. The lamp body 11 is disposed so as to incline outward in the vehicle width direction through a transparent resin bezel 30 attached to the opening 3 of the rocker panel 2. 3 indicates the optical axis of the lamp body 11.

  Specifically, the bezel 30 disposed in the opening 3 of the rocker panel 2 extending in the longitudinal direction of the vehicle body has a frame-type rearward extending portion (bulging portion) 34 that engages with the opening 3 of the rocker panel 2. Is formed. In other words, the bezel 30 is defined by a frame-shaped rearward extending portion (bulged portion) 34 so as to define a rectangular opening portion 32 that opens on the front side, which is a space portion in the present invention (Claim 3). The frame-type rear extension 34 is configured as a bottomed rear bulge, and the lamp body 11 (the front surface of the translucent case 14) is carried on the bottom wall 34a of the frame-type rear extension 34 ( The optical axis L of the lamp body 11 is disposed so as to incline outward in the vehicle width direction.

  In other words, the lamp body 11 is supported by the bezel 30 (the bottom wall 34a of the frame-shaped rearward extending portion 34) provided with the opening 32 through which the light emitted from the translucent case 14 can pass. The shaft L is disposed so as to be inclined downward with respect to a horizontal line H (see FIGS. 3 and 4) facing outward in the vehicle width direction.

  Therefore, the light emitted from the lamp body 11 (the front surface of the translucent case 14) passes through the bottom wall 34 a of the frame-type rear extension 34 of the bezel 30 and passes through the opening 32 of the bezel 30. Since the vehicle is guided to an area far away from the vehicle, a wide area of the road surface is uniformly illuminated.

  In addition, light emitted from the lamp body 11 (the front surface of the translucent case 14) is guided to a region far from the vehicle, but the light emitted from the translucent case 14 passes through the opening 32 of the bezel 30. In doing so, the light component that goes upward from the horizontal is blocked, and the following vehicle or the like does not illuminate the lighting of the lamp body 11 with the lighting of the backup lamp.

  Specifically, since the light emitted from the lamp main body 11 (the front surface of the translucent case 14) is guided to a region far from the vehicle, the lamp is passed through the opening 32 of the bezel 30 from the side or rear of the vehicle. Although the light exit surface of the translucent case 14 of the main body 11 may be directly visually recognized, as shown in FIGS. 3 and 4, the lowermost part P1 of the light exit surface of the translucent case 14 of the lamp body 11 is completely covered. The light emitting surface of the lamp body 11 (translucent case 14) is directly visible from the side or rear of the vehicle because it is positioned above the uppermost portion P2 of the opening 32 on the front surface of the zel 30. Never happen. That is, there is no illusion that the following vehicle or the like will turn on the lamp body 11 with the backup lamp. The symbol h indicates the vertical difference between the lowermost part P1 of the light exit surface and the uppermost part P2 of the opening 32.

  Further, the frame-type rearward extending portion 34 of the bezel 30 is configured as a bottomed rearwardly bulging portion having a bottom wall 34 a, so that it is excellent in waterproofness to the lamp body 11 and the opening 32 of the bezel 30. When mud enters and the inner surface of the frame-type rear extension 34 becomes dirty, the mud (dirt) can be easily removed by washing with water.

  In addition, the bezel 30 is painted in the same color as the vehicle body color on the front side of all regions except the bottom wall 34a of the frame-type rear extension 34 so that the vehicle body color is unified. Yes.

  Note that reference numeral 35 in FIG. 3 denotes locking projections provided at a plurality of positions in the longitudinal direction of the side wall of the frame-type rearward extending portion (bulging portion) 34 of the bezel 30. When the frame-shaped rearward extending portion (bulging portion) 34 is press-fitted into the portion 3 to be engaged, the temporarily fixing convex portion 35 is engaged with the peripheral portion on the back surface side of the opening portion 3, so that the bezel is 30 is held (temporarily fixed) in a form attached to the opening 3 of the rocker panel 2.

  In addition, the lamp body 11 is fixed to the back surface of the frame bracket 40 disposed so as to cover the frame-shaped rearward extending portion 34, and the rugged lance is engaged and fixed, as shown in FIG. The second legs 47 formed at both ends in the longitudinal direction of the frame are pressed together with the bezel 30 onto the opening peripheral edge 3a of the rocker panel 2 by the fastening screws 47a, thereby pressing the frame-type rear extension 34. Is held in.

  Specifically, at both ends in the longitudinal direction of the translucent case 14 constituting the lamp body 11, horizontal extending portions 14 b that are flush with the front surface of the translucent case 14 are formed, and in the width direction of the translucent case 14. Convex portions 15, 15 projecting outward are formed on the outer side surfaces 14 a, 14 a facing each other.

  On the other hand, as shown in FIGS. 5 and 6, a horizontal rib 40 a that supports the horizontal extension 14 b on the translucent case 14 side and a front surface of the translucent case 14 are provided on the back side of the frame-shaped bracket 40. A horizontal frame 40b for supporting the frame is formed. Reference numeral 40 c denotes an opening on the back side of the frame bracket 40. The horizontal frame 40b is provided at a predetermined position (a position corresponding to the connecting portion 22b that is an ineffective reflection surface) that does not interfere with the reflected light on the effective reflection surface 22a of the reflector 22.

  In addition, a tongue-like extension 42 is formed on the back side of the side walls 41, 41 facing the width direction of the frame bracket 40, and each tongue-like extension 42 has a translucent shape. A concave portion 43 is formed to engage with the convex portion 15 on the conductive case 14 side.

  Then, when the lamp body 11 is pushed in from the back side of the bracket 40 so as to be engaged between the tongue-like extension portions 42 and 42 facing each other, the horizontal extension portion 14b of the translucent case 14 and the front surface thereof are the bracket 40. The horizontal rib 40a and the horizontal frame 40b are in contact with each other, and the convex portion 15 on the translucent case 14 side is concavo-convexly engaged (elastically engaged) with the concave portion 43 on the tongue-like extension portion 42 side. Can be integrated.

  And as above-mentioned, the 2nd leg 47 of the frame type bracket 40 is the opening peripheral part 3a of the rocker panel 2 with the 2nd leg 47 of the frame type bracket 40 being fixed to the back surface side of the frame type bracket 40. (See FIG. 5), and as shown in FIG. 4, the first legs 45 formed on the side surfaces of the frame-type bracket 40 near the both ends in the longitudinal direction are formed on the opening peripheral edge 3a of the rocker panel 2. By being fastened with bolts and nuts (46a, 46b), they are held in a form pressed against the horizontal ribs 40a and the horizontal frames 40b of the frame-type rearward extending portion 34 of the bezel 30.

  In addition, the structure in which the lamp body 11 is supported at a position recessed from the opening 32 of the bezel 30 is a cantilever support structure in which the lamp body 11 is supported by the frame-type rear extension 34 of the bezel 30. There is anxiety that the durability of the support structure of the main body 11 is lowered, or the lamp main body vibrates due to vibration accompanying driving of the engine, the light distribution of the lighting device 10 is blurred, and the visibility of the road surface is lowered.

  However, in this embodiment, the bracket 40 that is fastened together with the bezel 30 together with the opening peripheral edge portion 3 a of the rocker panel 2 supports the lamp body 11, that is, a frame that covers the frame-type rearward extending portion 34 of the bezel 30. Since the mold bracket 40 supports the lamp body 11 in cooperation with the frame mold rear extension 34 of the bezel 30, the lamp body 11 is excellent in durability as a support structure of the lamp body 11, and the lamp body 11 vibrates as the engine is driven. Therefore, there is no problem that the light distribution of the lighting device 10 is shaken by shaking.

  Further, as shown in FIG. 5, the horizontal extending portions 14 b at both ends of the lamp main body 11 (the translucent case 14 thereof), together with the horizontal ribs 40 a of the bracket 40, the frame-type rear extending portion 34 (the bottom surface of the bezel 30). The strength of the lamp body 11 as a support structure is further enhanced by being fastened to the wall 34a) by the fastening screw 44.

  Specifically, if the lamp main body 11 is merely pressed and held by the frame extension 34 of the bezel 30, the front of the lamp main body 11 and the rear of the bracket 40 (horizontal rib 40a, horizontal There is a risk that the frame 40b) and the bottom wall 34a of the frame-type extension 34 of the bezel 30 may slide (vibrate) relatively along the respective pressing surfaces, but the lamp body 11 is positioned horizontally on the back side of the frame-type bracket 40. The relative displacement (vibration) of the lamp body 11 with respect to the frame-type extending portion 34 of the bezel 30 is surely suppressed by being fastened together with the rib 40 a and the frame-type extending portion 34 of the bezel 30.

  That is, in addition to the frame-type bracket 40 covering the frame-type extension part 34 of the bezel 34 supporting the lamp body 11 in cooperation with the frame-type extension part 34 of the bezel 30, By being fastened together with the frame bracket extending portion 34 of the bezel 30 together with the mold bracket 40, the strength (rigidity and durability) as the support structure of the lamp body 11 is further improved. The problem that the light distribution of the lighting device shakes due to vibration caused by the engine drive does not occur reliably.

  Furthermore, the cross section of the bracket 40 at the position where the horizontal frame 40b is formed is formed in a substantially trapezoidal shape (a substantially trapezoidal shape in which the distance between the opposing left and right side walls 41, 41 is wider toward the lower end side) to support the lamp body 11. Since the strength (rigidity and durability) of the entire bracket 40 to be secured is ensured, there is no possibility that the lamp body 11 will vibrate due to vibration accompanying driving of the engine and the light distribution of the lighting device 10 may be blurred.

  In FIG. 5, the boss 36 protruding from the back side of the bezel 30 passes through the boss hole 2 a provided in the opening peripheral edge 3 a of the rocker panel 2 and protrudes to the back side, and a sheet packing 49 is provided on the outer periphery of the boss 36. The second leg 47 of the frame bracket 40 is screwed to the boss 36 by a fastening screw 47a.

  That is, the boss 36 protruding from the back side of the bezel 30 and the boss hole 2 a provided in the opening peripheral edge 3 a of the rocker panel 2 are connected to the bezel engaging opening 3 of the rocker panel 2. The positioning means is configured.

  Further, the sheet packing 49 is made of a rubber-like elastic body, and is interposed between the frame bracket 40 and the bezel 30 as shown in FIGS. That is, the seat packing 49 functions as a buffer member for bringing the bezel 30 into close contact with the rocker panel 2, and the frame bracket 40 and the bezel 30 are fixed by the fastening screws 47a, whereby the bezel 30 is fixed to the rocker panel 2. Is pressed against the peripheral edge 3a.

  Next, a procedure for assembling the lamp body 11 with the bezel 30 and the frame bracket 40 at a predetermined position of the opening 3 of the rocker panel 2 will be described.

  First, the lamp body 11 is integrated with the frame bracket 40. That is, the lamp body 11 is pushed from the back side of the frame-type bracket 40 so as to engage between the opposing tongue-shaped extension portions 42, 42, and the convex portion 15 on the translucent case 14 side is extended in the shape of a tongue-like piece. When the concave / convex lance is engaged with the concave portion 43 on the protruding portion 42 side, the lamp body 11 is in a form in which the horizontal extending portion 14b and the front surface of the translucent case 14 are in contact with the horizontal rib 40a and the horizontal frame 40b of the bracket 40, respectively. Is integrated with the frame bracket 40. At this time, the lamp body 11 is sandwiched in the vertical direction by the concave / convex lance engaging portions (15, 43) between the back side of the bracket 40 (horizontal rib 40a, horizontal frame 40b) and the frame bracket 40.

  Subsequently, the frame-type rear extension 34 of the bezel 30 is press-fitted into the opening 3 of the rocker panel 2 so that the boss 36 on the back side of the bezel 30 engages with the boss hole 2 a of the rocker panel 2. The bezel 30 is temporarily fixed to the opening 3 of the rocker panel 2 by engaging the convex portion 35 for temporary fixing on the side of the bezel 30 with the peripheral portion on the back surface side of the opening 3.

  Next, from the back side of the rocker panel 2, the frame-type bracket 40 in which the lamp body 11 is integrated is placed on the frame-type rear extension 34 of the bezel 30, and the lamp body 11 is attached as shown in FIG. 5. The second leg 47 of the integrated frame-type bracket 40 is fastened together with the bezel 30 to the opening peripheral edge 3a of the rocker panel 2, and the rear surface of the frame-type bracket 40 that supports the lamp body 11 (horizontal rib 40a, horizontal The frame 40b) is pressed against the bottom surface of the frame-type rearward extension 34 of the bezel 30, and the first leg 45 of the frame-type bracket 40 is placed on the opening peripheral edge 3a of the rocker panel 2 as shown in FIG. Fasten bolts and nuts (46a, 46b).

  Finally, as shown in FIG. 5, the horizontal extension 14 b of the lamp body 11 (the translucent case 14 thereof) and the horizontal rib 40 a of the bracket 40 together with the frame-type rear extension 34 (the bottom wall of the bezel 30). Screw to 34a).

  The lighting device 10 of the above-described embodiment includes a lamp body 11 that forms a predetermined light distribution, a bezel 30 that is assembled to the vehicle body (rocker panel 2) and supports the lamp body 11, and the vehicle body (rocker panel 2). The bracket 40 is configured to be assembled and hold the lamp body 11 in a form in pressure contact with the bezel 30. The bezel 30 and the bracket 40 other than the lamp body 11 are configured in a shape corresponding to the shape of the vehicle body to be assembled. Thus, the lamp body 11 can be assembled to the body of an automobile of a different vehicle type. That is, the shape of the lower part of the side of the vehicle body (outdoor parts such as rocker panels and side sills) differs depending on the vehicle type, but by preparing a bezel and bracket corresponding to each vehicle type, The lamp body 11 can be used in common and attached to different types of vehicle bodies.
