[Example] Next, an example of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 to 7, a mirror stay 11 projects forward and outward from the cab 10 of the cab-over-type truck. The upper end of this stay 11 is the roof panel 10
a is rotatably supported via fixed stays 12 and 13,
The lower end is connected to the front panel 10 via the bracket 14.
It is rotatably supported by b. A line L connecting the upper and lower fulcrums of the stay 11 extends in the vertical direction. The stay 11 is formed by bending a metal pipe into a substantially U-shape. A side mirror 16 is supported on a vertical portion of the stay 11. The mirror 16 is rotated by a motor 21.

Specifically, a J-shaped support shaft 17 is fixed to a flat portion of the stay 11 by bolts 17a and nuts 17b, and a mirror 16 is rotatably mounted on the support shaft 17 via a bearing 18. A fan-shaped tooth 19 is fixed to the bearing 18, and a pinion 22 fixed to a shaft 21a of a motor 21 attached to the stay 11 meshes with the fan-shaped tooth 19. A rotation angle sensor 23 that detects the rotation angle of the side mirror 16 is connected to the shaft 21a.

One end of a first rod 26 is rotatably mounted on the upper portion of the mirror stay 11, one end of a second rod 27 is rotatably mounted on the other end of the rod 26, and the other end of the rod 27 is a roof panel. A nut 51 is fixed to an upper end of a pivot 50 that is rotatably provided on the 10a. Pivot 50 is a roof panel
It is supported by a pivot bearing 52 that extends through the 10a and into the cover. The bearing 52 is fixed to the roof panel 10a. One end of a rod 53 is fixed to the lower end of the pivot 50. rod
The other end of 53 is rotatably attached to one end of a rod 54, and the other end of rod 54 is rotatably attached to the upper surface of wheel gear 56. A worm gear 57 meshes with the wheel gear 56, and the output shaft of the motor 28 is connected to the worm gear 57.

Next, the operation of the side mirror device having such a configuration will be described.

First, when the truck makes a right turn on a narrow road and the mirror 16 may hit an obstacle, the switch 32 is switched to the position shown by the broken line. The controller 30 drives the motors 28 and 21 while comparing the changes in the outputs of the rotation angle sensors 23 and 29 with the reference values stored in the memory 35, and moves the stay 11 in the direction indicated by the arrow in FIG. In accordance with the rotation angle, the mirror 16 is rotated such that the mirror mirror surface always shows the rear view and the side view of the truck to the driver's eyes 37.

Switch when stay 11 and mirror 16 are rotating
If 32 is returned to the neutral position shown by the solid line, stay 11 and mirror
16 stops at the halfway position as shown in FIG. 6, and when the switch 32 is returned to the broken line position again, the stay 11 and the mirror 16 are further rotated from the halfway position to move the stay 11 to the cab 10 as shown in FIG. Can be approached.

If the switch 32 is switched to the position shown by the dashed line when the truck passes through the obstacle, the motors 28 and 21 are reversed and the state shown in FIG. 7 is changed from the state shown in FIG. It protrudes to the side of 10. Again, sensors 29 and 23
The controller 30 controls the motors 28 and 21
To rotate the stay 11 so that the mirror surface of the side mirror 16 always shows the driver's eyes 37 the rear view and the side view of the truck when the stay 11 rotates.

The mounting structure of the motor 21 and the rotating means of the stay 11 and the mirror 16 are not limited to the above example. Further, the mirror stay 11 is not limited to the U-shape, and only the upper end or only the lower end may be pivotally attached to the vehicle body.

[Effects of the Invention] As described above, according to the present invention, the mirror surface of the side mirror is always in the driver's eyes when the mirror stay is rotating or when the mirror stay is stopped. Is displayed, the driver can turn the vehicle more safely.

In particular, unlike the related art, there is an excellent effect that a side view can be projected in a folded state.
