To provide a valve clamping structure for a reciprocating type compressor capable of minimizing a dead volume between a cylinder and a piston, easily carrying out the stroke control of the piston and firmly fixing a suction valve to the piston.

This valve clamping structure for the reciprocating type compressor is composed by providing the piston 10 carrying out a linear reciprocating motion in the cylinder and having a coolant passage F formed inside in the same direction as the direction of the linear reciprocating motion, the suction valve 20 mounted to the tip surface of the piston 10 for opening and closing the coolant passage F of the piston 10, and magnets 30 pressed in and mounted to the tip surface of the piston 10 for fixing the suction valve 20 by means of a magnetic force.
