。[Claims for Utility Model Registration] (1) In a vibrating compressor that generates high-pressure gas through reciprocating motion of a piston, the piston includes a piston body and a piston that is protruded from the tip surface of the piston body.・A piston ring is provided between the piston head and the distal end surface of the piston body, the piston ring being slidably and airtight with the inner peripheral surface of the cylinder part. A vibratory compressor, characterized in that a radial ventilation groove serving as a ventilation flow path during suction is formed on an end surface of the piston head that contacts the piston ring. (2) The piston body is formed of a cylinder with a closed end surface, and is provided with a ventilation hole that penetrates the outer circumferential surface and inner circumferential surface of the cylinder at a position near the tip surface. The vibratory compressor according to claim (1), characterized in that: (3) The vibratory compressor according to claim (2), wherein a stepped portion is formed on the outer peripheral surface of the cylinder, reaching the tip end surface from the opening position of the ventilation hole.
