In the drawings, 1 is a piston, 3 is a piston pin engagement hole, 20 is a piston pin direction adjustment device, 35 is a detection section of a detection device, 1 is an axis of the piston pin engagement hole, and m is a piston axis.

Claims

[Claims for Utility Model Registration] A piston, in which the axis of the piston pin engagement hole does not intersect with the piston axis and is offset in the radial direction of the piston, is rotated about its axis, When the two detecting parts, which are arranged on both sides and have a receiving and transmitting function, detect the direction of the piston pin engaging hole through the piston pin engaging hole, the rotation of the piston is stopped and the direction of the piston is determined. In a piston direction adjustment device for positioning a piston, the direction of the piston pin engagement hole is determined by making the axis connecting the two detection parts of the detection device on the radial surface of the piston including the axis of the piston pin engagement hole. In addition, the axis connecting the detecting section is arranged on the side where the eccentric side of the piston pin engagement hole is desired to be positioned with respect to the piston axis, and the axis connecting the detecting section includes the piston axis. A piston direction regulating device characterized in that an inner surface of the piston pin engagement hole on a side farther from a plane parallel to an axis of the piston pin engagement hole is disposed along a position through which the piston passes due to rotation.
