A gas cycle engine for a small-sized, low-vibration and long-life refrigerator which is high in centering accuracy of a moving member and excellent in durability. In the gas cycle engine for such a refrigerator, a thermodynamic gas cycle is performed by using a moving member (2 and 3) disposed in a cylinder (1), supported by leaf springs so as to be movable in the axial direction of the cylinder and driven by a linear motor (9, 12 and 13), the leaf springs (4a and 4b) being made of an electrical conductor used also as current leads for supplying a current to the linear motor.
