It is covered by. The surface (mirror surface) of the mirror 18 is exposed to the rear side of the vehicle through the opening 16, so that a vehicle occupant (especially a driver) can visually recognize the rear side of the vehicle by the mirror 18.

  As described above, when the storage mechanism is normally operated, the mirror 18 (including the visor 14 and the reinforcement) is rotated and stored in the vehicle rear side and the vehicle width direction inner side with respect to the stand. (Folded). Further, when the retracting mechanism is reversely operated, the mirror 18 (including the visor 14 and the reinforcement) integrally with the rotating body is rotated to the vehicle front side and the vehicle width direction outer side with respect to the stand to be deployed (returned and raised). )

(Moveable) is supported. The lower surface of the housing 24 is exposed downward from the lower surface of the visor 14, and the lower surface of the housing 24 is disposed flush with the lower surface of the visor 14. A substantially rectangular columnar recess 28 is formed on the outer side of the housing 24 in the vehicle width direction, and the recess 28 is open to the rear side of the vehicle. The housing 24 is urged in a direction in which it is rotated downward.

  A substantially rectangular plate-shaped auxiliary mirror 30 as an additional portion is supported in the concave portion 28 of the housing 24, and the surface (mirror surface) of the auxiliary mirror 30 is directed to the rear side of the vehicle.

  A moving mechanism 34 is provided on the outer side of the bracket 20 in the vehicle width direction and on the front side of the vehicle.

  The moving mechanism 34 is provided with a motor 36. A control device 38 (see FIG. 3) is electrically connected to the motor 36. Under the control of the control device 38, the moving mechanism 34 is operated to rotate the motor 36.

  A worm 40 constituting a gear mechanism (deceleration mechanism) is coaxially fixed to the output shaft 36A of the motor 36, and the worm 40 is rotatable integrally with the output shaft 36A. A helical gear 42 (worm wheel) that constitutes a gear mechanism is meshed (engaged) with the worm 40, and the helical gear 42 rotates integrally with the rotating shaft 44 with the rotating shaft 44 fixed on the same axis. Has been made possible. A substantially elliptical columnar rotating column 44 </ b> A is integrally formed at the vehicle front side end of the rotating shaft 44, and the rotating column 44 </ b> A is disposed coaxially with the rotating shaft 44.

  A pinion 46 constituting a gear mechanism is coaxially fixed to the rotating shaft 44 on the vehicle rear side of the helical gear 42, and the pinion 46 can rotate integrally with the rotating shaft 44. The pinion 46 is engaged (engaged) with a spa 48 that constitutes a gear mechanism. The spa 48 is fixed to the housing 24 and extends along the circumferential direction of the support shaft 26 (the rotation direction of the housing 24). Stretched.

  Therefore, when the motor 36 is driven to rotate as described above, the output shaft 36A, the worm 40, the helical gear 42, the rotating shaft 44, the pinion 46, and the spa 48 of the motor 36 are rotated, and the moving body 22 rotates. Moved.

  As shown in FIG. 3, the control device 38 is electrically connected to an automatic transmission 50 (transmission) and a sensor 52 of the vehicle, and the sensor 52 is located on the rear side and the lower side of the vehicle door mirror device 10. An obstacle in the vicinity of the rear wheel (for example, in the vicinity of the rear wheel of the vehicle) (in particular, an occupant cannot be visually recognized by the mirror 18 and is lower than the lower end of the mirror 18 such as a pylon) can be detected.

  A lowering mechanism 54 as a lowering means shown in FIGS. 5 and 6 is provided on the vehicle front side of the rotating shaft 44 of the moving mechanism 34.

  The lowering mechanism 54 is provided with a substantially cylindrical intermediate bushing 56 as a communication means. The intermediate bushing 56 has a vehicle front side end portion of the rotating shaft 44 fitted coaxially therein, and is attached to the rotating shaft 44. It is supported.

  A pair of first pressing portions 56 </ b> A (see FIG. 7A) having a fan-shaped cross section is formed on the inner peripheral surface of the intermediate bush 56 at the position where the rotating column 44 </ b> A is disposed on the rotating shaft 44. Each of 56A protrudes radially inward of the intermediate bush 56 and faces each other. When the rotating shaft 44 is rotated and the rotating column 44A comes into contact with the pair of first pressing portions 56A, the rotating column 44A presses the pair of first pressing portions 56A, and is integrated with the rotating shaft 44 in the middle. The bush 56 is rotated.

  A pair of second pressing portions 56B (see FIG. 7B) having a fan-shaped cross section is formed on the inner peripheral surface of the intermediate bush 56 on the vehicle front side of the pair of first pressing portions 56A. The portions 56B protrude inward in the radial direction of the intermediate bush 56 and face each other.

  A rotary damper 58 as a resistance means is provided on the vehicle front side of the intermediate bush 56. The rotary damper 58 is provided with a main body portion 58 </ b> A, and the main body portion 58 </ b> A is fixed to the bracket 20. The main body portion 58A is provided with a resistance column 58B having a substantially elliptical column shape, and the resistance column 58B protrudes from the main body portion 58A toward the vehicle rear side. The resistance column 58 </ b> B is coaxially fitted in the intermediate bush 56 to support the intermediate bush 56, whereby the rotary damper 58 is connected to the rotating shaft 44 by the intermediate bush 56. The resistance column 58B is disposed at a position of the pair of second pressing portions 56B (see FIG. 7B) of the intermediate bush 56, and the intermediate bush 56 is rotated so that the pair of second pressing portions 56B is the resistance column 58B. When the pair of second pressing portions 56B press against the resistance column 58B, the resistance column 58B is rotated integrally with the intermediate bush 56, so that the resistance column 58B rotates with respect to the main body portion 58A. Is done. Further, when the resistance column 58B is rotated relative to the main body portion 58A, the main body portion 58A applies a predetermined rotational resistance force to the resistance column 58B.

  Next, the operation of this embodiment will be described.

  In the vehicle door mirror device 10 configured as described above, the moving body 22 is stored in the visor 14.

  When the automatic transmission 50 is set to the reverse range (reverse range) and the sensor 52 detects an obstacle on the vehicle rear side and the lower side of the vehicle door mirror device 10 (first opportunity), the moving mechanism 34 , The motor 36 is driven to rotate in one direction under the control of the control device 38, and the output shaft 36A, worm 40, helical gear 42, rotating shaft 44, pinion 46 and spa 48 of the motor 36 are rotated in one direction. Thus, the movable body 22 (including the auxiliary mirror 30) is rotated downward and deployed from the visor 14 to the lower side (may be diagonally downward in the front of the vehicle or diagonally downward in the rear of the vehicle) (see the solid line in FIG. 1). ).

  For this reason, the auxiliary mirror 30 is exposed to the lower side of the visor 14 so that the occupant can visually recognize the rear side and the lower side of the vehicle door mirror device 10 (particularly, the obstacle and its surroundings). Thereby, while preventing the change of the occupant's viewable range by the mirror 18, the occupant's viewable range can be expanded by the auxiliary mirror 30, so that the occupant can assist without changing the line of sight when the vehicle moves backward. The rear side and the lower side of the vehicle door mirror device 10 can be noted with the mirror 30.

  When the automatic transmission 50 is set to a range other than the reverse range and when the sensor 52 no longer detects an obstacle on the rear side and the lower side of the vehicle door mirror device 10 (second opportunity), the moving mechanism 34 The motor 36 is driven to rotate in the other direction under the control of the control device 38, and the output shaft 36A, the worm 40, the helical gear 42, the rotating shaft 44, the pinion 46 and the spa 48 of the motor 36 are rotated in the other direction. The moving body 22 (including the auxiliary mirror 30) is rotated upward and stored in the visor 14 (see the two-dot chain line in FIG. 1).

  Here, when the moving body 22 is deployed from the visor 14, the rotation shaft 44 is rotated in one direction (the direction of the arrow A in FIGS. 7A and 7B), and the rotation shaft 44 is rotated. The column 44A is brought into contact with the pair of first pressing portions 56A of the intermediate bush 56 (see the two-dot chain line in FIG. 7A), so that the rotating column 44A presses the pair of first pressing portions 56A to the middle. The bush 56 is rotated in one direction. Further, the intermediate bush 56 is rotated in one direction, and the pair of second pressing portions 56B of the intermediate bush 56 is brought into contact with the resistance column 58B of the rotary damper 58 (see a two-dot chain line in FIG. 7B). Thus, the pair of second pressing portions 56B presses the resistance column 58B and rotates it in one direction. Therefore, in the rotary damper 58, the resistance column 58B is rotated in one direction with respect to the main body portion 58A, and the main body portion 58A applies a rotational resistance force to the resistance column 58B, so that the resistance column 58B and the intermediate bush 56 are interposed. Thus, a rotational resistance force is applied to the rotation shaft 44, and a rotational resistance force is applied from the rotation shaft 44 to the output shaft 36 </ b> A of the motor 36 via the helical gear 42 and the worm 40.

  Thus, in the later stage of deployment of the moving body 22 from the visor 14 (when the rotating shaft 44 rotates the resistance column 58B in one direction via the intermediate bush 56), the output shaft 36A of the motor 36, the worm 40, the helical gear. 42, the rotating shaft 44, the pinion 46, and the spa 48 are rotated in one direction, and the rotational speed of the moving body 22 is decreased.

  On the other hand, when the moving body 22 is stored in the visor 14, the rotation shaft 44 is rotated in the other direction (the direction of arrow B in FIGS. 7A and 7B) to rotate the rotation shaft 44. The column 44A is brought into contact with the pair of first pressing portions 56A of the intermediate bush 56 (see the solid line in FIG. 7A), whereby the rotating column 44A presses the pair of first pressing portions 56A and the intermediate bush 56 Rotate in the other direction. Further, the intermediate bush 56 is rotated in the other direction, and the pair of second pressing portions 56B of the intermediate bush 56 is brought into contact with the resistance column 58B of the rotary damper 58 (see the solid line in FIG. 7B). The pair of second pressing portions 56B presses the resistance column 58B and rotates it in the other direction. Therefore, in the rotary damper 58, the resistance column 58B is rotated in the other direction with respect to the main body portion 58A, and the main body portion 58A applies a rotational resistance force to the resistance column 58B, so that the resistance column 58B and the intermediate bush 56 are interposed. Thus, a rotational resistance force is applied to the rotation shaft 44, and a rotational resistance force is applied from the rotation shaft 44 to the output shaft 36 </ b> A of the motor 36 via the helical gear 42 and the worm 40.

  Thereby, in the latter stage of storing the moving body 22 in the visor 14 (when the rotating shaft 44 rotates the resistance column 58B in the other direction via the intermediate bush 56), the output shaft 36A of the motor 36, the worm 40, the helical The rotational speed of the gear 42, the rotating shaft 44, the pinion 46, and the spa 48 in the other direction is decreased, and the rotational speed of the moving body 22 is decreased.

  As described above, the rotational speed of the moving body 22 is reduced in the later stage of deployment of the moving body 22 from the visor 14 and the later stage of storing the moving body 22 in the visor 14. For this reason, when the moving body 22 is deployed from the visor 14 and when the moving body 22 is stored in the visor 14, the occupant can feel the turning operation of the moving body 22 elegantly, and the vehicle door mirror device 10 can be given a high-class feeling.

  Further, the first stage of storing the moving body 22 in the visor 14 (before the rotating shaft 44 rotates the resistance column 58B in one direction via the intermediate bush 56) and the first stage of storing the moving body 22 in the visor 14 (rotating shaft). Before the resistance column 58B is rotated in the other direction via the intermediate bush 56), the moving body 22 is compared with the later stage of deployment from the visor 14 and the later stage of storage of the moving body 22 into the visor 14. The rotational speed of 22 is increased. For this reason, it can suppress that the time for the moving body 22 to expand | deploy from the visor 14 and the time for the moving body 22 to be stored in the visor 14 become unnecessarily long. In particular, since the time required for the moving body 22 to be deployed from the visor 14 can be prevented from being unnecessarily long, the occupant can visually recognize the rear side and the lower side of the vehicle door mirror device 10 with the auxiliary mirror 30 at an early stage.

  Further, the rotary damper 58 (the main body 58 </ b> A and the resistance column 58 </ b> B) applies a rotational resistance force to the rotary shaft 44 via the intermediate bush 56, whereby the rotational speed of the moving body 22 is reduced. For this reason, the rotational speed of the moving body 22 can be reduced with a simple configuration.

  In the present embodiment, the movable body 22 is deployed only when the automatic transmission 50 is in the reverse range and when the sensor 52 detects an obstacle on the rear side and the lower side of the vehicle door mirror device 10. It was. However, the moving body 22 may be deployed only when the automatic transmission 50 is set to the reverse range or only when the sensor 52 detects an obstacle on the vehicle rear side and the lower side of the vehicle door mirror device 10.

  In this embodiment, the moving mechanism 34 rotates the moving body 22 by the motor 36. However, the moving mechanism 34 may rotate the moving body 22 by a solenoid or biasing means.

  Furthermore, in this embodiment, the lowering mechanism 54 lowers the rotational speed of the moving body 22 by the resistance force of the rotary damper 58 (resisting means). However, the lowering mechanism 54 may reduce the rotation speed of the moving body 22 by the resistance force of the resistance means other than the rotary damper 58 (for example, the biasing force of the spring).

  In the present embodiment, the movable body 22 is made rotatable. However, the moving body 22 may be slidable.

  Further, in the present embodiment, the moving body 22 is developed below the visor 14. However, the moving body 22 may be deployed in another direction of the visor 14 (for example, the upper side, the vehicle front side, the vehicle rear side, the vehicle width direction outer side, or the vehicle width direction inner side).

  In the present embodiment, the auxiliary mirror 30 is provided on the moving body 22 as an additional portion. However, instead of or together with this, at least one of a display (display function unit), a camera (imaging function unit), a sensor (detection function unit), and a lamp (illumination function unit) as an additional unit in the moving body 22. May be provided.

  Furthermore, in this embodiment, the moving body 22 can be expanded and stored by the moving mechanism 34 with the moving body 22 as an additional body. However, the rotating body of the storage mechanism may be an additional body, and the rotating body may be developed and stored by the moving mechanism 34.

  In the present embodiment, the vehicle mirror device of the present invention is applied to the vehicle door mirror device 10. However, the vehicle mirror device of the present invention may be applied to another vehicle outer mirror device (for example, a vehicle fender mirror device) outside the vehicle or a vehicle inner mirror device inside the vehicle.
