In the compressor disclosed in Japanese Utility Model Laid-Open No. 62-133973, measures are taken to restrict rotation of the single-headed piston by interference between the inner peripheral surface of the housing and the back surface of the neck of the single-headed piston. Also, the actual Kaihei 4
In the compressor disclosed in Japanese Patent No. 499676, measures are taken to guide the neck portion of the single-headed piston by the fitting structure of the unevenness between the inner peripheral surface of the housing and the back surface of the neck portion of the single-headed piston. The side surface of the concave portion and the side surface of the convex portion face each other, and the facing structure of this side surface regulates the rotation range of the single-headed piston.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the measures disclosed in Japanese Patent No. 133973, the interference between the housing and the single-headed piston is the interference between the tip-shaped flat surface of the trapezoid protruding from at least one side and the other flat surface. It will be a hit. Therefore, the wear of the part that hits the corner is severe. As the wear progresses, the amount of rotation of the single-headed piston increases and the noise increases.

In the countermeasure disclosed in Japanese Utility Model Laid-Open No. 4-49676, since the rotation of the single-headed piston is almost completely suppressed, the noise due to the rotation of the single-headed piston does not occur. However, since the side surfaces of the concave portion and the convex portion are inclined with respect to the radial line centered on the axis of the piston, the rotating force of the piston causes a wedge effect between the concave portion and the convex portion. The wedge effect is an effect that when a wedge-shaped member is driven into a slit, a load larger than the driving force is applied to the slit surface. Such a wedge effect increases the frictional force between the opposing side surfaces of the concave portion and the convex portion, and the reciprocating movement of the piston causes severe wear at the opposing portion of the concave portion and the convex portion that slides at high speed.
