Claims (5)

  A cylinder including a working medium, and a piston and a displacer that are slidably fitted in the cylinder and arranged in parallel, and a reciprocating motion of the piston and the displacer forms a compression space and an expansion space in the cylinder. In the Stirling engine, the outer peripheral surface of one or both of the piston and the displacer is composed of first and second outer peripheral surface portions having different processing accuracy.   A cylinder including a working medium, and a piston and a displacer that are slidably fitted in the cylinder and arranged in parallel, and a reciprocating motion of the piston and the displacer forms a compression space and an expansion space in the cylinder. In the Stirling engine, the piston is formed with a through-hole through which a rod projecting from the displacer is slidably inserted, and the inner peripheral surface of the through-hole has first and second inner peripheries having different processing accuracy. Stirling engine characterized by comprising a face part.   A cylinder enclosing a working medium; and a piston and a displacer that are slidably fitted in the cylinder and arranged side by side; and on one end side of the displacer facing the piston by a reciprocating motion of the piston and the displacer A Stirling engine that forms a compression space and forms an expansion space on the other end of the displacer, wherein the displacer includes first and second members having different materials and outer diameters. The Stirling engine according to claim 3 , wherein the thermal conductivity of the first member arranged on the expansion space side is lower than the thermal conductivity of the second member arranged on the compression space side. A storage comprising the Stirling engine according to any one of claims 1 to 4 .
