PROBLEM TO BE SOLVED: To provide a compact, solid and inexpensive manually rotated and driven device capable of being simply handled and requiring no wide space for storage when compared with a conventional device. SOLUTION: This manually rotated and driven device is composed of a rhombus-shaped arm supporting mutual fulcrums 21 to 24 pivotally and turnably by forming a rhombus-shape by four arms 11 to 14, a base 16 supporting the first fulcrum 24 pivotally and turnably, a pin 36 provided at the second fulcrum 21 opposing to the first fulcrum 24 and fixed detachably in a pin hole 32 of a rotary part 31 of the elevator hoisting machine 30, a screw 18 connecting the third fulcrum 22 and the fourth fulcrum 23 mutually, and a lever 15 provided in an end part of the screw 18 and rotating the screw 18. By rotating the lever 15, a rotary part engaging member 36 provided at the second fulcrum 21 is moved vertically. COPYRIGHT: (C)2005,JPO&NCIPI
