徴とする流体圧機関のピストン構造。 A pressure pocket is formed in the piston that reciprocates within the cylinder block, and a deformable portion is provided outside the pressure pocket to elastically deform in the radial direction of the piston in response to changes in the pressure of the fluid introduced into the pressure pocket. A piston structure for a fluid pressure engine, characterized in that an annular protrusion for sealing is integrally provided on the outside of the deformed portion and is adjacent to the inner wall surface of the cylinder cylinder block through a small gap.
