PURPOSE:To aim at smooth operation over a long period of time, by connecting a transfer piece, projected out of a cam follower which converts reciprocating motion of a cam into both centripetal and centrifugal motions to a rotary disk axis, to a slider on an extension of the rectilinear transfer route. CONSTITUTION:Four straightening claws 8a, 8b, 9a and 9b are set up in a rotary disk 2 at intervals of 90 deg., and sliders 40a, 40b, 41a and 41b support each of these claws. On the other hand, reciprocating motion of the wedgelike cam 26 set up on an axis of the rotary disk 2 is converted into both centripetal and centrifugal motions to the axis of the rotary disk 2 by a cam follower 30a. The transfer piece 33a projectingly locked to the top of this cam follower 30a is connected to the said slider 41a on an extension of the rectilinear transfer route or the vicinity, transmitting movements of the cam follower 30a to it. In consequence, since so much moment as making the slider produce its partial wear will not happen, smooth operation over a long period of time is continuable.
