る、ピストンリング張出し装置。 A piston ring is installed in a groove provided along the outer circumference of the piston, and a coil spring and a plunger shaft are installed in a hole drilled in the piston, so that the plunger pushes the piston ring due to the reaction force of the spring. In a piston ring extension device that presses against the inner wall of a cylinder, one end of the spring has a large diameter and presses against the groove of the piston, and the diameter near the one end is larger than the diameter of the hole of the piston. The plunger has a curved shape and is locked at the edge of the hole, and the other end is fixed to the end of the plunger shaft,
Moreover, the piston ring extension device is characterized in that the plunger shaft passes through the spring and is assembled into the hole of the piston with the spring extended.
