PROBLEM TO BE SOLVED: To lessen the loss of power by lessening the resistance of lubricating oil in a balancer of a crank shaft in a Stirling refrigerator and at the same time supply the lubricating oil in a mechanically sliding portion stably by reducing the dissipation of the lubricating oil. SOLUTION: The balancer 57 smoothly contacts in a condition of small resistance applied from the lubricating oil stored in the bottom of a crank chamber 5 by attaching the balancer 57 of a blade profile in cross section to the crank shaft 7 when the balancer 57 of the blade profile rotates together with the crank shaft 7.
