【Example】

 An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 2, the rear-view mirror 17 and the under-mirror 21 are provided on the mirror stay 7 by the mirror arms 15 and 19, respectively, to form the left fender rear-view mirror 5. As shown in FIG. 1A, the mirror stay 7 is fixed to a rotary shaft 23 that is rotatable about a substantially vertical axis. The rotary shaft 23 penetrates through the inside of the outer cylinder 25, and the outer cylinder 25 is fixed to the fender 9 with bolts and nuts. The lower end of the rotary shaft 23 penetrating the outer cylinder 25 is engaged with a lever 27, and the lever 27 is rotated by a motor 29.

At the upper end of the outer cylinder 25, the diameter of the rotary shaft 23 is expanded and a step 31 is formed. Therefore, the rotary shaft 23 is supported by the outer cylinder 25 by the step 31. A spring pin 33 is horizontally fixed to the rotary shaft 23 in the plane forming the step 31. On the other hand, in the edge portion of the upper end of the outer cylinder 25, a groove 35 large enough to fit the spring pin 33 is formed.

A nylon bush 37 is attached so as to have durability against sliding of the two 25 and 23 when the rotary shaft 23 rotates with respect to the outer cylinder 25. A rubber seal 39 is provided so as to prevent rainwater and the like from entering the outer cylinder 25 through the step 31 and thus has a waterproof effect.

At the lower end of the rotary shaft 23, a projection 41 having a fan shape in a horizontal cross section is formed (FIG. 1B). Only in the portion where the protrusion 41 is formed, the radius of the rotary shaft 23 is increased in a fan shape. The other part has a reduced diameter and a smaller radius. A hole 43 having a radius slightly larger than the increased radius is formed in the lever 27. A fan-shaped protrusion 45 is formed inside the hole 43. The inside of the protrusion 45 is close to the small diameter portion of the rotary shaft 23. The lower end of the rotary shaft 23 is coaxially inserted into the hole 43 of the lever 27, and when the lever 27 rotates largely, both the protrusions 41 and 45 come into contact with each other so that the rotary shaft 23 can rotate. Wear.

A coil spring 49 is provided below the lever 27 near the hole 43 via a washer 47, and a lower end of the coil spring 49 is engaged with a lower end of the rotary shaft 23 via a washer 51. It has been stopped. The upper side of the lever 27 is in contact with the outer cylinder 25 and the nylon bush 53. Like the nylon bush 53, this nylon bush 53 provides durability against sliding. Due to the function of the coil spring 49, the rotary shaft 23 receives a downward force on the outer cylinder 25.

The lever 27 is rotatably supported by the motor bracket 55 (FIG. 3), and can be rotated by a motor 29 in any direction and at any angle. The motor 29 is a motor for a wiper, for example. The motor 29 can be operated by a switch 57 provided in the driver's seat.

The operation of this embodiment will be described below with reference to FIG. 5A and 5B are horizontal sectional views for explaining the action of the spring pin 33 on the upper side (A to D) and horizontal sectional views for explaining the movement of the lever 27 on the lower side (a to d).

FIGS. 5A and 5A show a state in which the fender rearview mirror 5 projects toward the outer side of the vehicle body and functions as a mirror (see FIG. 2). The spring pin 33 fixed to the rotary shaft 23 is inserted into the groove 35 of the outer cylinder 25 and positions the fender rearview mirror 5 in the rotational direction. In this embodiment, the groove 35 is formed at two positions with a pitch of 180 °, and the spring pin 33 has protrusions at both ends in the groove 35. In (a), the protrusion 45 of the lever 27 and the protrusion 41 of the rotary shaft 23 are separated by 180 °, and in this state, the angle θ formed between the two protrusions 45 and 41 is a play, and the fender back This is a safety measure when the mirror 5 comes into contact with an obstacle or the like and a force exceeding a predetermined value is applied.

From the states (A) and (a), when the switch 57 is turned on and the motor 29 rotates, only the lever 27 rotates for about 90 °. After rotating by 90 ° ((B) and (b) in the figure), the protrusion 45 of the lever 27 comes into contact with the protrusion 41 of the rotating shaft 23, the rotating shaft 23 starts to rotate, and the spring pin 33 rides over the groove 35 and comes out. Go to. During the subsequent 180 ° ((C) and (c) in the figure), the lever 27 and the rotating shaft 23 rotate together, and the spring pin 33 rotates while sliding on the upper edge of the outer cylinder 25. (Figure 4). Eventually, the spring pin 33 rotates 180 ° from the initial state ((A) in the figure) and enters the groove 35 again. In this state, the fender rearview mirror 5 is stored and positioned. In this stored state, the possibility that an obstacle or the like hits the fender rearview mirror 5 is extremely small, so it is considered that there is no need for play between the two protrusions 41 and 45, but the motor 29 is controlled and the lever 27 is moved in the opposite direction. The play may be secured by automatically rotating (clockwise).

In order to bring the fender rearview mirror 5 out of the stored state ((D) and (d) in the figure) again, the lever 27 is rotated again by 180 ° in the counterclockwise direction (see the figure). Inside (B) and (b), the spring pin 33 is inserted into the groove 35 in a state of being rotated by 180 °, and positioning is performed. At this time, in order to create a play between the two protrusions 41 and 45, the motor 29 is automatically rotated in the opposite direction and returned to the initial state ((A) and (a) in the figure).

Control of such a motor can be sufficiently handled by a known technique (for example, an auto return mechanism). As described above, the operation of the switch 57 for rotating 180 ° or 90 ° can be sufficiently handled by the manual operation by the silent confirmation. In addition, if a switch with a two-step pushing amount, such as that used in power windows of automobile doors, is used, manual operation and one-touch operation (load fluctuation when spring pin 33 enters groove 35) are performed. It is also possible to selectively use the ones that are turned off.

In the above-described embodiments, the outer cylinder 25 is formed with the grooves 35 at two positions at a pitch of 180 °, and the spring pin 33 is also provided with the projecting portions at both ends. However, in other embodiments. Only one of the groove and the protrusion may be provided.
