Abstract
A groove in a direction of a crank shaft is provided in an inner surface of a top wall of a cup-shaped inner sleeve. The groove provides a stop for a semicylindrical slidable guide member that cooperates with a cylindrical concave portion of a cylindrical member to smoothly guide oscillation of a pair of arms at a small end portion of a connecting rod. Further, the slidable guide member allows relative sliding movement of the small end portion of the connecting rod in the direction of a crank shaft but inhibits relative rotation along the center axis of the piston.
