Claims

[Claim for Utility Model Registration] In an electric retractable mirror device that retracts and restores a vehicle's mirror using electric remote control, an operation switch that selects retraction operation and return operation, and when the retraction side is selected by this operation switch. A retraction timer that operates, a return timer that operates when the return side is selected by the operation switch above, and a return timer that operates when the above operation switch operates, switches the contact to one end of the power supply and connects the drive motor to the power supply side. A first relay that switches the contact to the other end of the power supply, and a first relay that switches the contact to the other end of the power supply when the recovery timer is activated, and connects it to the drive motor, usually the other end of the power supply. a second relay that switches a contact to one end of the power source; and when the contact of the first relay is switched to one end of the power source and connected, the power source is connected to the drive motor to perform the storage operation, and the second relay is connected to the drive motor. A connection circuit consisting of a plurality of backflow prevention elements connected to the drive motor in a connected state in which the power supply performs the return operation when the relay contacts are switched to one end of the power supply, and the return position of the mirror is determined. An electric retractable mirror device comprising: a return detection switch for detecting a return position; and a brake circuit comprising a transistor and a resistor for applying an electric brake to the drive motor when the return detection switch detects a return position.
