The vehicle front wall of the cover 54 is disposed on the vehicle rear side of the regulated plate 48D, and the vehicle front wall of the cover 54 regulates the movement of the regulated plate 48D toward the vehicle rear side, thereby regulating the movement of the first light guide 48 toward the vehicle rear side. This regulates the rotation shaft 48E of the first light guide 48 from being removed from within the support piece 36 of the housing 24.

[0053] Next, the operation of this embodiment will be described.

[0054] In the door mirror device 10 having the above configuration, in the lamp device 22, the first LED 44 of the circuit board 42 emits light to the vehicle width direction inner end surface of the first light guide 48, so that the first light guide 48 guides the light incident on the vehicle width direction inner end surface and irradiates it from the vehicle width direction outer end surface. Furthermore, the light irradiated from the vehicle width direction outer end surface of the first light guide 48 is transmitted through the vehicle width direction outer end wall of the exposed portion 38C of the first lens 38, and is radiated in a direction toward the vehicle width direction outer side as it moves toward the rear of the vehicle through the vehicle width direction outer end surface of the exposed hole 14 of the visor 12. The color of the light radiated from the first lens 38 is amber, and the first LED 44, the first light guide 48, and the first lens 38 function as a turn lamp of the vehicle to notify the outside of the vehicle of the traveling direction of the vehicle.

[0055] In addition, the second LED 46 of the circuit board 42 emits light to the inner end surface of the second light guide 50 in the vehicle width direction, so that the second light guide 50 guides the light incident on the inner end surface in the vehicle width direction and irradiates it from the outer end surface in the vehicle width direction. Furthermore, the light irradiated from the outer end surface in the vehicle width direction of the second light guide 50 is transmitted through the vehicle rear wall of the second lens 40 and is radiated in a direction toward the inside of the vehicle width direction (toward the occupant) as it moves toward the rear of the vehicle through the open hole 16 of the visor 12. The color of the light radiated from the second lens 40 is amber (different in brightness and intensity from the light radiated from the first lens 38), and the second LED 46, the second light guide 50, and the second lens 40 function as a BSM (Blind Spot Monitor) of the vehicle to notify the occupant of the approach of another vehicle to the rear of the vehicle and to the outside in the vehicle width direction.

[0056] 11A and 11B, in the lamp device 22, before the second light guide 50 is assembled to the housing 24, the circuit board 42 is assembled in the assembly box 24A of the housing 24, and the second lens 40 is assembled to the vehicle width direction outer end wall of the housing 24. Then, the second light guide 50 is slid toward the rear of the vehicle (the opposite side to the removal direction of the mold for molding the inside of the housing 24) and accommodated in the housing 24. Therefore, the vehicle width direction outer end of the second light guide 50 is fitted into the second lens 40. Furthermore, the second light guide 50 is fitted into the upper convex portion 32 of the housing 24 and between the pair of regulating claws 28, and the regulating pillar 50A of the second light guide 50 is fitted into the regulating hole 26 of the housing 24. In this way, the second light guide 50 is assembled to the housing 24.

[0057] 12A and 12B, before the first light guide 48 is assembled to the housing 24, the cover 54 is fixed inside the outer end of the housing 24 in the vehicle width direction, and the shade 52 is attached to the circuit board 42 (not shown in FIGS. 12A and 12B). Then, after the rotation shaft 48E of the first light guide 48 is fitted into the support piece 36 of the housing 24, the first light guide 48 is rotated around the rotation shaft 48E toward the rear of the vehicle and accommodated in the housing 24. Therefore, the first light guide 48 is fitted into the lower protrusion 34 of the housing 24, and the regulated plate 48D of the first light guide 48 is disposed directly below the regulating plate 54B of the cover 54. Furthermore, the second light guide 50 is inserted through the fitting recess 48B of the upper locking piece 48A of the first light guide 48, and the circuit board 42 is fitted into the restriction recesses 48C of the upper and lower locking pieces 48A, so that the claw portion 18A of the upper locking claw 18 and the claw portion 30A of the lower locking claw 30 of the housing 24 are locked with the upper and lower locking pieces 48A, respectively. This completes the assembly of the first light guide 48 to the housing 24.

[0058] Here, the first light guide 48 is rotated and assembled to the housing 24, and the second light guide 50 is slid and assembled to the housing 24. Therefore, the first light guide 48 and the second light guide 50 can be easily assembled, improving the assembly performance of the lamp device 22. Moreover, since the methods of assembling the first light guide 48 and the second light guide 50 to the housing 24 are different, erroneous assembly of the first light guide 48 and the second light guide 50 to the housing 24 can be suppressed.

[0059] Furthermore, by fitting the circuit board 42 into the restricting recesses 48C of the upper and lower locking pieces 48A, the first light guide 48 restricts the movement of the circuit board 42 in the vehicle width direction and toward the front of the vehicle. This simplifies the configuration for restricting the movement of the circuit board 42 in the vehicle width direction and toward the front of the vehicle. Moreover, the accuracy of the relative position between the first light guide 48 and the first LED 44 of the circuit board 42 can be increased, and the light emitted by the first LED 44 can be appropriately incident on the first light guide 48.

[0060] Furthermore, the second light guide 50 passes through and fits into the fitting recess 48B of the upper locking piece 48A of the first light guide 48, so that the first light guide 48 restricts the movement of the second light guide 50 in the up-down direction and toward the front of the vehicle. This simplifies the configuration for restricting the movement of the second light guide 50 in the up-down direction and toward the front of the vehicle.

[0061] Furthermore, the first light guide 48 restricts the movement of the second light guide 50 in three directions (up and down directions and toward the front of the vehicle). Therefore, the first light guide 48 can restrict the movement of the second light guide 50 effectively.

[0062] Furthermore, as described above, the first light guide 48 restricts the movement of the circuit board 42 and the second light guide 50, thereby increasing the accuracy of the relative position between the second light guide 50 and the second LED 46 on the circuit board 42, and allowing the light emitted by the second LED 46 to properly enter the second light guide 50.

[0063] Further, a rotation shaft 48E is disposed on the outer side in the vehicle width direction of the first light guide 48, and an insertion portion (outer end portion in the vehicle width direction) into the second lens 40 is provided on the outer side in the vehicle width direction of the second light guide 50. Therefore, the first light guide 48 and the second light guide 50 can be assembled on the outer side (same side) of the first light guide 48 and the second light guide 50 in the vehicle width direction.

[0064] Moreover, the outer end (insertion portion) of the second light guide 50 in the vehicle width direction is inserted into the second lens 40. Therefore, the second light guide 50 can be easily assembled to the second lens 40.

[0065] Furthermore, the rotation of the side of the first light guide 48 opposite the rotation axis 48E (the upper and lower locking pieces 48A) toward the front of the vehicle is locked by the upper locking claw 18 and the lower locking claw 30 of the housing 24. This makes it possible to easily and satisfactorily restrict the rotation of the first light guide 48 toward the front of the vehicle.

[0066] In this embodiment, the light emitted from the first lens 38 and the light emitted from the second lens 40 are the same color (amber). However, the light emitted from the first lens 38 and the light emitted from the second lens 40 may be different colors.

[0067] Furthermore, in this embodiment, a rotation shaft 48E is provided in the first light guide 48, and the rotation shaft 48E is rotatably supported by the housing 24. However, the rotation shaft 48E may be provided in the housing 24, and the first light guide 48 may be rotatably supported by the rotation shaft 48E.

[0068] Furthermore, in this embodiment, when the second light guide 50 is assembled to the housing 24, the outer end portion in the vehicle width direction of the second light guide 50 is inserted into the second lens 40. However, before the second light guide 50 is assembled to the housing 24, the outer end portion in the vehicle width direction of the second light guide 50 may be inserted (or fixed) into the second lens 40, and the second light guide 50 may be assembled to the housing 24 together with the second lens 40.

[0069] Furthermore, in this embodiment, the first light guide 48 and the second light guide 50 are aligned in the vertical direction. However, the first light guide 48 and the second light guide 50 may be aligned in the horizontal direction (for example, the vehicle width direction).

[0070] In this embodiment, the viewing mechanism is the mirror 20. However, the viewing mechanism may be a camera, and the passenger's viewing may be assisted by an image captured by the camera. [Explanation of symbols]
