PURPOSE:To obtain rotary motion over 360 deg. by using both spherical or columnar parts and a disc which has at the outer periphery grooves into which the said parts are fitted. CONSTITUTION:A disc 1 is provided which has at the outer periphery grooves 11 into which spherical or columnar parts 2 are fitted at a regular interval. In addition, both a passage 21 in which the parts 2 move and a piston 3 which operates in acylinder by the aid of hydrodynamic force. The parts 2 stand side by side in the passage 21 in such a manner that they touch with each other. One of the parts 2 located at one extreme end touches a rod 31, while one of the parts 2 located at the other extreme end touches a rod 32. In addition, it is constituted that each of the parts 2 is engaged with one of the grooves 11 of the disc 1 in the middle of the passage 21. With this constitution, an angle of rotation of an output shaft 12 can be made over 360 deg.. |
