摘要： A crankshaft has eccentric holes communicating with each other. The eccentric hole extends in the axial direction of the crankshaft from one end surface of the crankshaft and is disposed so as to be eccentric in the same direction as a cam section. The eccentric hole extends in the axial direction of the crankshaft from the other end surface of the crankshaft and is disposed so as to be eccentric in the direction of the eccentricity of a cam section. A centrifugal force due to the rotation of the crankshaft generates a force couple about an axis which is perpendicular to the axis of the crankshaft. The force couple is reduced by the eccentric holes. The cam sections are arranged around the axis of rotation with the phases shifted by 180 degrees from each other. As a result, a translational force acting in the direction perpendicular to the axis of the crankshaft is also reduced.

摘要： A floating chuck mechanism provided at a workhead that is arranged at a processing apparatus for sandwiching a cylindrical-shaped workpiece by means of two center members along a rotational axis, the floating chuck mechanism causing the workpiece to rotate about the rotational axis and correcting an eccentricity between the rotational axis and a center of an outer diameter of the workpiece, includes a chuck body portion including plurality of clamp jaws for holding the workpiece from the outer peripheral side thereof, and a chuck base portion fixed to the workhead so as to rotate therewith, the chuck base portion including a fixed portion fixed to the workhead and a slide portion slidable along a slide surface perpendicular to the rotational axis. The chuck body portion is fixed to the slide portion and sliding along the slide surface so as to correct the eccentricity.
