[0030] A long, approximately rectangular box-shaped lens 24 is provided as a transparent member on the vehicle front side of the housing 20, and the lens 24 is made transparent to allow light to pass through, and is exposed to the outside of the visor 14 through the open hole 16 of the visor 14.

[0031] A covering box 24A having a substantially rectangular parallelepiped shape is provided at the inner end of the lens 24 in the vehicle width direction, and the interior of the covering box 24A is open to the rear side of the vehicle. The covering box 24A is fitted into and fixed to the assembly box 20A of the housing 20, and the covering box 24A covers the front side of the assembly box 20A.

[0032] A long, approximately rectangular parallelepiped-shaped transmission box 24B is integrally provided on the outer side of the covering box 24A in the vehicle width direction, and the interior of the transmission box 24B is connected to the interior of the covering box 24A. The transmission box 24B is curved toward the rear of the vehicle as it extends outward in the vehicle width direction, and the interior of the transmission box 24B is open to the rear side of the vehicle and the inner side in the vehicle width direction. The transmission box 24B is fitted into and fixed to the arrangement box 20B of the housing 20, and the transmission box 24B covers the front side of the arrangement box 20B and the outer side in the vehicle width direction. The outer end wall of the transmission box 24B in the vehicle width direction covers the rear side of the outer end of the arrangement box 20B in the vehicle width direction, and the outer end wall of the transmission box 24B in the vehicle width direction is exposed to the rear side of the vehicle from the outer end of the opening 16 of the visor 14 in the vehicle width direction.

[0033] A substantially rectangular circuit board 26 is mounted in the assembly box 20A of the housing 20, and is disposed substantially perpendicular to the vehicle width direction. A rectangular mating plate 26A serving as a mating portion is integrally formed on the lower portion of the circuit board 26, and the mating plate 26A protrudes toward the front of the vehicle.

[0034] A pair of male terminals 40 (see FIG. 5 ) are provided on the inner side of the circuit board 26 in the vehicle width direction, and the pair of male terminals 40 are aligned vertically. The middle portion of the male terminal 40 is formed in a substantially bent rectangular plate shape and is bent at a bending portion 40A to have an L-shaped cross section, with the outer portion of the middle portion of the male terminal 40 arranged parallel to the circuit board 26 in the vehicle width direction and the inner portion of the middle portion of the male terminal 40 arranged perpendicular to the vertical direction. A pair of connecting pieces 40B having an L-shaped plate cross section are provided on the base end portion of the male terminal 40, and the connecting pieces 40B extend from the middle portion of the male terminal 40. The extending tip side portions of the connecting pieces 40B penetrate the circuit board 26, and the extending tip side portions of the connecting pieces 40B are fixed and electrically connected to the circuit board 26 by solder (not shown). The tip end portion of the male terminal 40 is rod-shaped, and extends from the middle portion of the male terminal 40 toward the rear of the vehicle and is inserted into the male case 20C of the housing 20 (assembly box 20A).

[0035] A female connector 42 (see FIG. 8(B)) is connected to the male case 20C. The female connector 42 is provided with a female case 42A that is substantially cylindrical and has a bottom, and the male case 20C is fitted into the female case 42A and is locked to the male case 20C. A pair of female terminals (not shown) are provided inside the female case 42A, and the female terminals are electrically connected to the tip end portions of the male terminals 40 and press the male terminals 40, and therefore the circuit board 26, towards the front of the vehicle.

[0036] An LED 28 (see FIGS. 7A to 7C) having a generally rectangular plate shape as an emission section is fixed to the outer surface of the circuit board 26 in the vehicle width direction. The LED 28 is electrically connected to the vehicle control device 30 via the circuit board 26, male terminals 40 of the circuit board 26, and female terminals of the female connector 42, and the LED 28 emits light under the control of the control device 30 and emits light from the outer surface in the vehicle width direction. A turn signal switch 32 as an operating section of the vehicle is electrically connected to the control device 30, and the turn signal switch 32 is operated by a vehicle occupant (particularly the driver).

[0037] A long, substantially plate-shaped light guide 34 is provided between the housing 20 and the lens 24, and the light guide 34 is transparent so that it can transmit and guide light.

[0038] The light guide 34 is provided with a substantially cylindrical pipe 36 as a main body, and the pipe 36 is curved toward the rear of the vehicle as it extends outward in the vehicle width direction, except for its inner end (base end) in the vehicle width direction. A cylindrical incident recess is formed coaxially on the inner end surface of the pipe 36 in the vehicle width direction, and the inner end surface of the pipe 36 in the vehicle width direction faces the outer surface (light exit surface) of the LED 28 of the circuit board 26 in the vehicle width direction.

[0039] Except for the inner end in the vehicle width direction, the upper and lower sides of the pipe 36 are integrally formed with long, curved plate-like flanges 38 as protrusions, and the flanges 38 are curved in a direction toward the rear of the vehicle as they extend outward in the vehicle width direction. The upper and lower flanges 38 protrude upward and downward, respectively, and the protrusion amount of the inner end (base end) in the vehicle width direction of the flanges 38 is large.

[0040] A substantially rectangular columnar mounting piece 38A serving as a mounting portion is integrally formed on the vehicle front side of the inner end of the flange 38 in the vehicle width direction, and the mounting piece 38A protrudes inward in the vehicle width direction. The upper and lower mounting pieces 38A are attached to the upper and lower sides of the upper mounting claws 22 and the lower mounting claws 22 of the housing 20 (inside the assembly box 20A) by elastic deformation of the upper and lower mounting claws 22, respectively, and the mounting piece 38A abuts against the vehicle rear side surfaces of the claw portions 22A of the mounting claws 22. A substantially rectangular parallelepiped fitting recess 38C (see FIG. 3(B) and FIGS. 4(A) and (B)) serving as a recess is formed on the vehicle rear side surface of the mounting piece 38A, and the fitting recess 38C is open upward and downward as well as toward the vehicle rear side. The corners of the fitting recess 38C on the vehicle rear side (opening side) and both sides in the vehicle width direction are curved, and the opening of the fitting recess 38C expands on both sides in the vehicle width direction as it approaches the vehicle rear side. The circuit board 26 is inserted into the fitting recess 38C and fitted in the vehicle width direction, and the vehicle front end face of the circuit board 26 abuts against the vehicle front side surface (bottom surface) of the fitting recess 38C, and the fitting plate 26A of the circuit board 26 is fitted in the vertical direction between the upper and lower mounting pieces 38A (see FIG. 3(A)). Therefore, the vehicle width direction inner end of the light guide 34 is attached within the assembly box 20A and positioned in the vehicle front-rear direction and up-down direction.

[0041] Positioning pieces 38B in the shape of a substantially rectangular plate are integrally formed on the inner surface of the outer end of the flange 38 in the vehicle width direction, and the upper and lower positioning pieces 38B protrude upward and downward, respectively, as they move inward in the vehicle width direction. The tips of the positioning pieces 38B abut against the inner surface of the arrangement box 20B of the housing 20, and the outer end of the light guide 34 in the vehicle width direction abuts against the outer wall of the covering box 24A of the lens 24, thereby positioning the outer end of the light guide 34 in the vertical and transverse directions.

[0042] Next, the operation of this embodiment will be described.

[0043] In the door mirror device 12 configured as described above, when the occupant operates the turn signal switch 32 to change the traveling direction of the vehicle, the LED 28 of the circuit board 26 is controlled by the control device 30 to intermittently emit light toward the inner end surface in the vehicle width direction of the pipe 36 of the light guide 34. Therefore, the light guide 34 (pipe 36 and flange 38) guides the light incident on the inner end surface in the vehicle width direction of the pipe 36 and irradiates it from the front side surface, outer side surface, and outer end surface in the vehicle width direction, so that the light is intermittently emitted toward the front side, outer side, and rear side of the vehicle of the visor 14 via the front wall, outer wall, and outer end wall of the lens 24 in the vehicle width direction and the open hole 16 of the visor 14, thereby notifying the traveling direction of the vehicle.

[0044] When the turn signal lamp 10 is assembled, in the first step shown in Figures 6(A) and 7(A), the circuit board 26 is inserted (temporarily placed) into the assembly box 20A of the housing 20, and the tip portion of the male terminal 40 of the circuit board 26 is inserted into the male case 20C of the assembly box 20A.

[0045] 6(B) and 7(B) and 7(C), the light guide 34 is inserted into the housing 20, whereby the mounting pieces 38A of the light guide 34 (flange 38) are attached to the mounting claws 22 of the housing 20 (inside the assembly box 20A), and the inner end of the light guide 34 in the vehicle width direction is positioned in the vertical direction. Furthermore, the circuit board 26 is inserted into the fitting recesses 38C of the mounting pieces 38A, and the fitting plates 26A of the circuit board 26 are fitted in the vertical direction between the upper and lower mounting pieces 38A, and the positioning pieces 38B of the light guide 34 (flange 38) are abutted against the inner surface of the arrangement box 20B of the housing 20.

[0046] 6(C), the lens 24 is fitted and fixed to the housing 20, and the outer end of the light guide 34 in the vehicle width direction is brought into contact with the outer wall in the vehicle width direction of the covering box 24A of the lens 24. As a result, the outer end of the light guide 34 in the vehicle width direction is positioned in the up-down direction and the vehicle width direction.

[0047] 6(D) and 8(A) to 8(C), the male case 20C of the housing 20 (assembly box 20A) is fitted into the female case 42A of the female connector 42, and the female case 42A is engaged with the male case 20C. As a result, the female terminals in the female case 42A press the male terminals 40 of the circuit board 26 toward the front of the vehicle, thereby pressing the circuit board 26 toward the front of the vehicle, so that the front end surface of the circuit board 26 abuts against the front-of-vehicle surface of the fitting recess 38C in the mounting piece 38A of the light guide 34, and the mounting piece 38A abuts against the rear-of-vehicle surface of the claw portion 22A of the mounting claw 22 in the housing 20 (inside the assembly box 20A). As a result, the inner end of the light guide 34 in the vehicle width direction is positioned in the front-to-rear direction of the vehicle.

[0048] Here, the vehicle front end face of the circuit board 26 abuts against the vehicle front side surface of the fitting recess 38C of the mounting piece 38A of the light guide 34, and the position of the circuit board 26 in the vehicle longitudinal direction is set by the light guide 34. Furthermore, the circuit board 26 is fitted into the fitting recess 38C in the vehicle width direction, and the position of the circuit board 26 in the vehicle width direction is set by the light guide 34. Moreover, the fitting plate 26A of the circuit board 26 is fitted in the vertical direction between the upper and lower mounting pieces 38A, and the position of the circuit board 26 in the vertical direction is set by the light guide 34. Therefore, because the position of the circuit board 26 is set only by the light guide 34, the relative positional accuracy between the circuit board 26 and the light guide 34 can be increased, and the relative positional accuracy between the LEDs 28 of the circuit board 26 and the light guide 34 can be increased. This increases the accuracy with which the outer surface (light emission surface) of the LED 28 in the vehicle width direction faces the inner end surface of the pipe 36 of the light guide 34 in the vehicle width direction, allowing the light emitted by the outer surface of the LED 28 in the vehicle width direction to accurately enter the inner end surface of the pipe 36 in the vehicle width direction, increasing the amount of light emitted by the light guide 34. Furthermore, because the position of the circuit board 26 is not determined by the housing 20, stress from the housing 20 acting on the circuit board 26 and the light guide 34 can be limited.

[0049] Furthermore, the fitting recess 38C of the mounting piece 38A of the light guide 34 is enlarged in the vehicle width direction at the opening toward the rear of the vehicle, so that the circuit board 26 can be easily inserted into the fitting recess 38C, and the circuit board 26 can be easily fitted into the fitting recess 38C in the vehicle width direction.

[0050] Furthermore, the female terminals of female connector 42 (inside female case 42A) press male terminals 40 of circuit board 26 toward the front of the vehicle, and the front end surface of circuit board 26 is pressed against the front surface of fitting recess 38C in mounting piece 38A of light guide 34. This makes it possible to prevent the relative positions of circuit board 26 and light guide 34 from changing.

[0051] Moreover, a curved portion 40A is provided in the middle portion of male terminal 40 on circuit board 26. Therefore, even if an external force is applied to the tip side portion of male terminal 40 from the female terminal of female connector 42, the external force acts on circuit board 26 from the middle portion of male terminal 40, thereby preventing stress from acting on the connection portion of male terminal 40 to circuit board 26 (the portion where connection piece 40B is fixed to circuit board 26 by soldering), and preventing damage to the connection portion of male terminal 40 to circuit board 26.

[0052] Furthermore, on the inner side of the circuit board 26 in the vehicle width direction (the side opposite the LED 28), the mounting piece 38A of the light guide 34 is attached to the mounting claw 22 of the housing 20 (inside the assembly box 20A). This allows the distance between the positioning piece 38B of the light guide 34 and the mounting claw 22 to be increased, and positional deviation of the light guide 34 can be appropriately suppressed.

[0053] In the above embodiment, the female terminals of the female connector 42 press the male terminals 40 of the circuit board 26 toward the front of the vehicle, and the vehicle front end face of the circuit board 26 is pressed against the vehicle front side surface of the fitting recess 38C in the mounting piece 38A of the light guide 34. However, a crushing rib (compression portion) may be provided to protrude from the vehicle front side surface of the vehicle rear side wall of the assembly box 20A of the housing 20. In this case, the crushing rib is crushed by the vehicle rear side end face of the circuit board 26, and the crushing rib presses the circuit board 26 toward the front of the vehicle, and the vehicle front end face of the circuit board 26 is pressed against the vehicle front side surface of the fitting recess 38C in the mounting piece 38A of the light guide 34.

[0054] Furthermore, in the above embodiment, the circuit board 26 is separate from the light guide 34. However, the circuit board 26 may be fixed to the light guide 34 and integrated with the light guide 34.

[0055] In the above embodiment, the door mirror device 12 (visualization device) is provided with the mirror 18. However, the visualization device may be provided with a camera (visualization mechanism).

[0056] Furthermore, in the above embodiment, the visual confirmation device is the door mirror device 12 and is provided on the side door of the vehicle. However, the visual confirmation device may be a fender mirror device and may be provided on the fender of the vehicle. [Explanation of symbols]
