Abstract
PURPOSE: To improve operability of a lever by mounting a spring so as to accumulate restoring force between an input side rotary member rotating by lever operation and an output side rotary member connected to a wire in moving the lever in one direction, and not to accumulate in moving the lever in the other direction. CONSTITUTION: When a lever 34 is operated in normal direction, a changeover arm 44 is rotated, an input side ratchet claw 56 is struck to rotate the ratchet claw 56 inward, it is detached from a ratchet gear 58, and an input side rotational movement member 47 is rotated in the normal direction. Hereby, steel balls 71 fitted into the holes 70 of the input side rotational movement member 47 are moved in order to adjoining recessed parts 68 to wind up a spiral spring 54. Hereby, a wire reel 35 is rotated in the normal direction integratedly with an intermediate side rotating member 50 through an intermediate side ratchet claw 61 to wind up a wire and make an eccentric acting body eccentric. By operating the lever 34 in the reverse direction, the wire is pushed out by restoring force of the spring 54. By this constitution, the operability is improved.
