PURPOSE:To enable correct and automatic angle regulation of beckmirror by providing a solenoid from fixed frame through an oil damper while facing with a magnetic material provided above, below, left and right of supporting section on the back of backmirror. CONSTITUTION:When conducting the solenoid in the equipment X the facing iron plate 11 is absorbed to absorve the left end of backmirror 1 to the backside. The rod 12 is absorved simultaneously thus the piston 15 compresses the oil at the partition side 18 in the oil cylinder, thereby the compressed oil flows slowly through small orifice 19 to the partitions 20, 17 thus to brake the adsorption of iron board 11 due to the solenoid 13 and damps the adsorption. Consequently the fine adjustment is achieved and when the power is interrupted the piston 15 is stopped to hole the backmirror at the position. |
