  The speed reduction mechanism 14 and the clutch mechanism 15 of the rotational force transmission mechanism are provided between the output shaft 28 of the motor 13 and the shaft 10 as shown in FIGS. A force is transmitted to the shaft 10. The motor 13 and the speed reduction mechanism 14 and the clutch mechanism 15 of the torque transmission mechanism rotate the mirror assembly 2 relative to the shaft 10.

  The speed reduction mechanism 14 includes a first worm gear 29 as a first-stage gear, a helical gear 30 as a second-stage gear meshing with the first worm gear 29, and a second gear as a third-stage gear. A worm gear 31 and a clutch gear 32 as a final gear with which the second worm gear 31 is engaged are configured.

  The first worm gear 29 is rotatably supported by the bearing portion 40 of the plate 16 via a pin 33. The first worm gear 29 is connected to the output shaft 28 of the motor 13. The helical gear 30 is rotatably supported by the bearing portion 40 of the plate 16. The second worm gear 31 is rotatably connected to the helical gear 30 and is rotatably supported by the gear case 11.

  The clutch mechanism 15 includes the metal clutch gear 32, a metal clutch holder 35, a spring 36, a push nut 37, and a metal washer 38. The clutch mechanism 15 is configured by sequentially fitting the washer 38, the clutch holder 35, the clutch gear 32, and the spring 36 to the shaft 10 and compressing the spring 36 with the push nut 37. Has been. The clutch gear 32 and the clutch holder 35 are connected so as to be intermittent. When the second worm gear 31 of the speed reduction mechanism 14 and the clutch gear 32 of the clutch mechanism 15 are engaged with each other, the rotational force of the motor 13 is transmitted to the shaft 10.

  The clutch gear 32 and the clutch holder 35 constitute a clutch member. The clutch gear 32 is attached to the shaft 10 so as to be rotatable and movable in the axial direction. The clutch holder 35 is attached to the shaft 10 so as to be non-rotatable and movable in the axial direction. A plurality of, in this example, three chevron-shaped clutch projections are formed on the mutually opposing surfaces of the clutch gear 32 and the clutch holder 35, that is, on the lower surface of the clutch gear 32 and the upper surface of the clutch holder 35. And valley-shaped clutch recesses are provided at equal intervals. When the clutch convex portion and the clutch concave portion are in a fitted state, the clutch gear 32 and the clutch holder 35 are in a connected state, and the clutch convex portion and the clutch concave portion are in a disengaged (released) state. The clutch gear 32 and the clutch holder 35 are in a disconnected (released) state.

  Among the clutch members, the clutch gear 32 faces the spring 36 side, while the clutch holder 35 of the clutch members faces the washer 38 and the gear case 11 side. The washer 38 is fixed to the gear case 11. The clutch holder 35 and the washer 38 are provided with an electric rotation range restricting mechanism for restricting the electric rotation range of the mirror assembly 2. The electric rotation range restricting mechanism restricts the electric rotation range between the use position C and the storage position B of the mirror assembly 2. In addition to the restriction at the retracted position B of the mirror assembly 2 by the electric rotation range restricting mechanism, the stopper surface 25 of the gear case 1 contacts the stopper surface 22 of the stopper convex portion 21 of the shaft holder 9. As a result, the position of the mirror assembly 2 may be restricted to the storage position B.

  The electric retractable door mirror device 1 in this embodiment is configured as described above, and the operation thereof will be described below.

  First, as shown in FIG. 1, the case where the mirror assembly 2 located at the use position C is electrically rotated to the storage position B and stored is described. When the mirror assembly 2 is in the use position C, the clutch convex portion of the clutch gear 32 and the clutch concave portion of the clutch holder 35 are in a fitted state, so that the clutch gear 32 and the clutch holder 35 are in a continuous state. . For this reason, the clutch gear 32 is in a state in which it cannot rotate with respect to the shaft 10 together with the clutch holder 35.

  In this state, the motor 13 is driven by operating a switch (not shown) in the interior of the automobile. Then, the rotational force of the motor 13 is transmitted to the clutch gear 32 fixed to the shaft 10 via the output shaft 28 and the speed reduction mechanism 14. At this time, the clutch gear 32 is in a state in which it cannot rotate with respect to the shaft 10 together with the clutch holder 35, so the second worm gear 31 of the speed reduction mechanism 14 rotates around the clutch gear 32. By this rotation, the mirror assembly 2 including the electric storage unit 3 is rotated about the shaft 10. With this rotation, the mirror assembly 2 rotates clockwise from the use position C to the storage position B as shown in FIG.

  At this time, the bearing portion 40 of the plate 16 is fitted to the fitting portion 44 of the gear case 11 so that there is no movement in the direction intersecting the shaft 10, and the contact portion 41 of the plate 16 and the gear are engaged. The contact portion 45 of the case 11 contacts each other in the direction of the shaft 10, and the locking claw 43 of the elastic wall 42 of the plate 16 and the locking recess 46 of the gear case 11 mutually contact each other in the direction of the shaft 10. Elastic locking. For this reason, the plate 16 is fixed to the gear case 11 and the cover 12 so that there is no movement in the direction of the shaft 10 and no movement in the direction crossing the shaft 10. As a result, the rotational force transmission mechanism can operate smoothly.

  When the mirror assembly 2 rotates clockwise from the use position C to the storage position B, the gear case 11 of the electric storage unit 3 similarly rotates clockwise with respect to the shaft 10. When the mirror assembly 2 is located at the retracted position B, the electric rotation range regulating mechanism increases the value of the current (operating current) supplied to the motor 13 to reach a predetermined value, and the switch circuit is activated to operate the motor. The current supply to 13 is cut off. As a result, the mirror assembly 2 stops and is positioned at the storage position B of the predetermined position shown in FIG. At this time, the stopper surface 22 of the stopper projection 21 of the shaft holder 9 contacts the stopper surface 25 of the gear case 11. Thereby, the rotation of the mirror assembly 2 is restricted, and the contact between the mirror assembly 2 and the vehicle body is avoided.

  Next, as shown in FIG. 1, the case where the mirror assembly 2 positioned at the storage position B is electrically rotated to the use position C and returned is described. That is, the motor 13 is driven by operating a switch (not shown) in the interior of the automobile. Then, as shown in FIG. 1, the mirror assembly 2 rotates counterclockwise from the storage position B to the use position C.

  Accordingly, the gear case 11 of the electric storage unit 3 rotates counterclockwise with respect to the shaft 10, and the mirror assembly 2 is positioned at the use position C. Then, due to the action of the electric rotation range regulating mechanism, the value of the current (operating current) supplied to the motor 13 increases and reaches a predetermined value, the switch circuit is activated and the current supply to the motor 13 is cut off. . As a result, the mirror assembly 2 stops and is positioned at the use position C of the predetermined position shown in FIG.

  Furthermore, as shown in FIG. 1, the case where the mirror assembly 2 is manually rotated between the use position C and the storage position B will be described. The mirror assembly 2 located at the use position C or the storage position B is manually rotated clockwise or counterclockwise. Then, the fitting state between the clutch concave portion of the clutch holder 35 that cannot rotate on the shaft 10 and the clutch convex portion of the clutch gear 32 is released against the spring force of the spring 36. As a result, the clutch gear 32 can rotate with respect to the shaft 10, and thus rotates around the shaft 10 together with the second worm gear 31 of the speed reduction mechanism 14.

  By this rotation, the mirror assembly 2 including the electric storage unit 3 is rotated about the shaft 10. As a result, as shown in FIG. 1, the mirror assembly 2 rotates in the clockwise direction from the use position C to the storage position B or in the counterclockwise direction from the storage position B to the use position C.

  Furthermore, as shown in FIG. 1, the mirror assembly 2 located at the use position C is manually rotated counterclockwise. Then, the gear case 11 attached to the mirror assembly 2 tries to rotate counterclockwise. At this time, the clutch gear 32 and the clutch holder 35 cannot rotate with respect to the shaft 10, so that the clutch gear 32 and the clutch holder 35 move (rise) against the spring force of the spring 36. . As a result, as shown in FIG. 1, the mirror assembly 2 rotates counterclockwise from the use position C to the forward tilt position A and is positioned at the forward tilt position A. At this time, the stopper surface 22 of the stopper projection 21 of the shaft holder 9 contacts the stopper surface 25 of the gear case 11. Thereby, the rotation of the mirror assembly 2 is restricted, and the contact between the mirror assembly 2 and the vehicle body is avoided.

  Furthermore, as shown in FIG. 1, the mirror assembly 2 positioned at the forward tilt position A is manually rotated clockwise. Then, the gear case 11 attached to the mirror assembly 2 rotates in the clockwise direction. As a result, as shown in FIG. 1, the mirror assembly 2 rotates clockwise from the forward tilt position A to the use position C. When the mirror assembly 2 is located at the use position C, the clutch gear 32 and the clutch holder 35 are moved (lowered) by the spring force of the spring 36 as shown in FIG. As a result, the mirror assembly 2 is located at the use position C by the action of the electric rotation range restriction mechanism.

  In addition to the manual rotation described above, even when a load is applied to the mirror assembly 2 in the clockwise direction or in the counterclockwise direction, as shown in FIG. 2 rotates between the use position C and the storage position B, or between the use position C and the forward tilt position A.

  The electric retractable door mirror device 1 in this embodiment is configured and operated as described above, and the effects thereof will be described below.

  In the electric retractable door mirror device 1 in this embodiment, the fitting portion 44 of the gear case 11 is fitted so that the bearing portion 40 of the plate 16 does not move in the direction intersecting the shaft 10, and the gear case 11 and the contact portion 41 of the plate 16 are brought into contact with each other in the direction of the shaft 10, and the engagement recess 46 of the gear case 11 and the engagement claw 43 of the elastic wall 42 of the plate 16 Are elastically locked to each other in the direction of the shaft 10 in a state where the contact portion 45 of the gear case 11 and the contact portion 41 of the plate 16 are in contact with each other. For this purpose, the electric retractable door mirror device 1 in this embodiment has a plate 16 on the gear case 11 and the cover 12 without using a fastening part such as a screw, that is, a separate part. It can be fixed so that there is no movement in the direction crossing 10. As a result, the electric retractable door mirror device 1 according to this embodiment does not require a fastening part such as a screw, that is, a separate part, and does not require a work for fastening a fastening part such as a screw. Can be achieved.

  In particular, in the electric retractable door mirror device 1 in this embodiment, the locking recess 46 of the gear case 11 and the locking claw 43 of the elastic wall 42 of the plate 16 are elastically locked. 46 and the locking claw 43 of the elastic wall 42 of the plate 16 are securely locked, and the movement between the gear case 11 and the plate 16 can be stopped reliably.

  In addition, the electric retractable door mirror device 1 in this embodiment can fix the plate 16 to the gear case 11 and the cover 12 without using a fastening part such as a screw so that there is no movement. Failure due to fastening of fastening parts, for example, excessive stress is applied to the plate 16 and the plate 16 is deformed, and the speed reduction mechanism 14 is affected, so that the operation noise increases or the durability performance deteriorates. There are no defects.

  Hereinafter, examples other than the above-described embodiment will be described. In the above-described embodiment, an electrically retractable door mirror device will be described. However, the present invention can also be applied to a vehicle outside mirror device other than the electrically retractable door mirror device. For example, the present invention can be applied to a vehicle outside mirror device such as a vehicle fender mirror device.
