PURPOSE: A movement change apparatus is provided to reduce costs by elastically changing a variable pin in a rotating radius direction of a crank according to load of a slider. CONSTITUTION: One end of a rotating radius direction of a crank(10) is steadily circumscribed in an input shaft. The input shaft receives torque from outside. A One end of a connecting rod(20) is combined with the other end of the rotating radius direction of the crank by a link pin(P). The link pin changeably moves along the rotating radius direction of the crank by a rotating radius variable unit. A slider(30) straightly reciprocates along a guide rail(31) fixed to a frame. A reaction unit compresses the link pin in the outside direction of the rotating radius direction of the crank.
