Abstract

PURPOSE: To cause smooth noiseless reciprocation in operation, by providing a reciprocating body which has two projections on its inside surface and providing a rotatable cam which is located inside the reciprocating body and has several projections at equiangular intervals.
CONSTITUTION: When a driving shaft 1 is rotated in a direction A, the sliding contact face 11a of a projection 3a is pushed in the direction A by the tip face 10a and the first cam face 8a of a projection 2a of a cam 2 in a state shown in Fig. As a result, a reciprocating body 3 oriented by guides 4, 5 is moved in a direction L as shown by a one-dot chain line. Since the second cam face 9c of a projection 2c always slides in contact with a projection tip 12b, the reciprocating body 3 is smoothly moved without play to the cam 2. When the cam 2 is rotated further, a projection 2b acts in the same way to another projection 3b of the reciprocating body 3 having reached a position shown by a one-dot chain line and the body 3 is moved in a direction R.
