By reducing the occurrence of noise can be convenient to the driver, the material of the clutch gear and catch plate made of a small alloy from synthetic resin to reduce the manufacturing cost, the driving device for the electric folding rearview mirror.

In driving a car, the rearview mirror plays a very important role in driving safety by allowing the driver to understand the situation around the car.

However, since the rearview mirror protrudes on the front side of the vehicle, there is a very high possibility of causing a contact accident by the rearview mirror when parking in a narrow space or when crossing a narrow road.

In order to solve such a problem, an electric folding rearview mirror that allows the driver to conveniently control the folding and unfolding of the rearview mirror in the driver's seat has been developed, and the conventional electric folding rearview mirror is a rotating power transmitted from the electric motor seated on the upper case. The position of the rear view mirror is controlled by using a drive that transmits the worm wheel.

As an example of the technology related to the driving device of the electric folding rearview mirror, the guide protrusion formed on the upper case and the guide portion formed on the motor cap are used to fill the space between the upper case and the electric motor, The technology to improve the service life of the electric motor by the shock and vibration transmitted from the vehicle body by allowing the cover to be mounted with a simple structure is disclosed in Korean Utility Model Registration No. 20-0331436 (Notice date: 2003 October 30).

As another example of the technology related to the driving device of the electric folding rearview mirror, an opening is formed in the motor insertion pocket formed in the upper case and the electric motor is deformed due to the deformation of the dimension that is likely to occur according to the injection condition of the motor insertion pocket. The technology to improve the lifespan of the motors by fixing the electric motors using the motor fixing bands and effectively protecting them from shocks and vibrations transmitted from the vehicle body. 20-0349771 (published: May 8, 2004) was disclosed by the applicant.
