PURPOSE: To very smoothly and finely control the tilting of the surface of a mirror, by securing a piston on the back of the mirror and by supplying a working fluid to the piston through a hose while regulating the fluid by a fluidic logical element circuit.
CONSTITUTION: To turn the surface 1 of a mirror leftward, an operating switch 15 is pushed leftward so that a working fluid flows into a hose 11 through a fluidic logical element circuit 13 and the rod 7 of a piston 4 is pulled. To turn the mirror surface 1 rightward, opposite operation is effected. To swing the surface 1 of the mirror upward, an operating switch 14 is pushed upward so that the working fluid flows into a hose 9 through the fluidic logical element circuit 13, the rack 6a of the rod 6 of a piston 7 is pulled downward and a gear 5 is rotated. To swing the mirror surface 1 downward, opposite operation is effected.
