PURPOSE:To securely operatively shift left and right door mirrors by shifting said mirrors to regular and housing positions with a momentary type control switch, and shifting said mirrors always to the housing position when the mirrors is in any position other than the regular one. CONSTITUTION:When housing position detecting switches 25, 26 for left and right door mirrors are in the non-detecting condition and a control switch 19 is operated, left and right forward rotation relays 29, 30 form self-holding circuits A, C and forward rotation circuits B, D of left and right drive motors 21, 22 until the switches 25, 26 reach the detecting condition. As a result, the drive motors 21, 22 rotate forward to pivot the mirrors to the housing position. Reversely, when the switch 19 is operated and a condition detecting circuit 39 detects the detecting condition of the switches 25, 26 left and right reversion relay a 48, 49 form self holding circuits E, G and reversal rotation circuits F, H of motors 21, 22 when mirror regular position detecting switches 27, 28 are under the non-detecting condition so that motors are reversely rotated to pivot the mirrors to the regular position. |
