PURPOSE:To simplify operation of mirror driving apparatus, by incorprating a pump in the body of a control valve and carrying out on-off control of motor together with switching of fluid flow. CONSTITUTION:Control valve 10 consists of a spherical hollow body 11, valve body 12 and control knob 13, and in the hollow body 11, ports 111 to 113 connectrd to pipes 91 to 93 are provided equidistantly in the same plane passing the center of said spherical body. Rotatable blades 14a of pump 14 are incorporated in the valve body 12, and they are formed integrally with output shaft 151 of motor 15. Further, movable contact 131a for driving motor 15 is provided at one end 131 of conrol knob 13. With such an arrangement, movable contact 131a and fixed contact 114a are brought into contact with each other or disengaged from each other by handling the control knob 13 and output shaft 151 of motor 15 is caused to rotate or stop correspondingly, whereby oil is supplied from pump 14 via pipes 91 to 93 to the hollow body 11 to tilt and turn the mirror. |
