Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric mirror device used for a large vehicle with an overbody type such as a truck or a bus.
[0002]
[Prior art]
Conventionally, on the front part of a vehicle-oversized large vehicle such as a truck, in order to visually confirm the lower side or the rear side of the vehicle, for example, on the passenger seat side, a rear confirmation mirror, a lower confirmation mirror, or a side lower side confirmation A mirror or the like is attached via a large stay (for example, see Patent Document 1).
[0003]
FIG. 4 shows an example.
The electric mirror device 1 includes a mirror mounting stay 3 that protrudes to the front side of the windshield 2.
The mirror mounting stay 3 is bent in a U-shape, and a lower-view mirror 4, a rear-view mirror 5, a side-view lower-view mirror 6, and the like are mounted at appropriate positions of the mirror mounting stay 3. In order to reduce the weight of the mirror mounting stay 3, a metal tube or a solid metal rod may be used. The rear view mirror 5 is composed of an electric rearview mirror that is rotated by a motor, and further includes a mirror heating heater.
[0004]
A base portion 3a on the upper end side of the mirror mounting stay 3 is attached to a turning shaft 10 of a housing 9 that houses a motor capable of rotating in the forward and reverse directions and a rotation driving member driven by the motor. A lower end 3 b of the mirror mounting stay 3 is rotatably supported by the bracket 7 by a lower end support shaft 11. The bracket 7 is fixed to a member (for example, a pillar) outside the vehicle body 12.
[0005]
The housing 9 has leg portions 13, 14 and 15. The housing 9 and the leg portions 13, 14, 15 are fixed to each other by a set screw. The leg portions 13, 14, 15 are fixed to the vehicle body side member 16 by fixing parts 17, 18, 19 such as bolts.
[0006]
