Figures 1 to 5 show an embodiment of the present invention, with Figure 1 being a cross-sectional view showing the internal structure of the compressor, Figure 2 being a longitudinal sectional view around the compressor, and Figure 3 being a rotary piston. A vertical cross-sectional view of the area around the concave groove showing the state in which the hetip seal is inserted, Figure 4 is a vertical cross-sectional view showing the movement of the seal ring when the rotary piston is moving toward the outer circumference, and Figure 5 is a vertical cross-sectional view of the rotary piston. FIG. 4 is a vertical cross-sectional view showing the movement of the seal ring when the seal ring is moving toward the center. Figures 6 and 7 show a conventional example, Figure 6 is a view of the same part as Figure 1 of a compressor that uses a conventional tip seal, and Figure 7 is a longitudinal section showing the movement of the tip seal due to the movement of the rotary piston. It is a front view. 2...Oilless compressor, 3...Cylinder, 4
