An apparatus for mutual conversion between circular motion and reciprocal motion includes a lever member which is rotatably mounted on a line connecting a rotational center and a circumference of a rotary disk, the lever member having a fulcrum, an action point and a force point, and being provided with a first regulator serving as an action point regulator and a second regulator serving as a movable fulcrum regulator. The first regulator is coupled to a reciprocating body. The movable fulcrum regulator has support members for supporting the fulcrum point and the first regulator has support members for supporting the action point in a longitudinal direction of the lever member.
