And a conductive coil spring. Then, power is supplied to a coil placed in a magnetic field via the pair of conductive coil springs arranged concentrically with respect to the axis of the displacer.

る。Japanese Patent Laid-Open Publication No. Hei 6-257872 discloses another embodiment in which the displacer is provided at two places separated in the axial direction of the displacer by two leaf springs arranged in parallel at right angles to the axis. An arrangement is shown which is held against a cylinder and which feeds a coil placed in a magnetic field via this leaf spring.

がある。In the above-mentioned prior art, a material using a pair of conductive coil springs has a long life because a material having good electrical conductivity and high fatigue strength can be used as the material of the coil spring. There is an advantage that you can.

難であるという問題があった。However, in the case of a coil spring, a certain accommodation length is required even when the coil spring is contracted. In addition, since the rigidity in the lateral direction (the direction perpendicular to the axis) is low, a distance or space is required to prevent a short circuit of the conductive coil spring due to displacement in the lateral direction or a ground fault to surrounding components. In particular, when the linear motor is used in a spacecraft, the lateral displacement is remarkable due to vibration at the time of launch. As a result, there is a problem that it is difficult to reduce the size of the power supply unit.

型化が困難であるという問題があった。On the other hand, in the case of a leaf spring, the above-mentioned rigidity in the lateral direction is not so problematic. However, in the case of the conventional example, the leaf spring is disposed at two places separated in the axial direction of the displacer and parallel to the axis at right angles. Since the displacer is held by the two leaf springs with respect to the cylinder, it does not contribute much to shortening the length in the axial direction, and when trying to obtain a predetermined stroke, the length of the leaf spring is reduced. It must be long, and consequently the cylinder diameter must be large. Therefore, also in this case, there is a problem that it is difficult to reduce the size of the power supply unit.

２５００に一定の低温を発生させる。When an alternating current having a predetermined frequency is supplied to the movable coil 1310 from an external power supply, the movable coil 1310 reciprocates in the gap 1306 due to the interaction between the alternating current and the magnetic field in the annular gap 1306. The compression piston 1204 connected to the coil 1310 reciprocates in the compression cylinder 1202. When the flow of the refrigerant gas generated by the reciprocating motion of the compression piston 1204 passes through the regenerator 2300 of the displacer 2200, the displacer 2200 reciprocates in the expansion cylinder 2100 by the force generated by the fluid resistance. A vibration system is configured by the mass of the displacer 2200, the fluid resistance of the regenerator 2300, and the strength of the support spring 2600.
By appropriately selecting the reciprocating cycle of the compression piston 1204, the displacer 2200 and the compression piston
04 reciprocates synchronously with mutually different phases. When the compression piston 1204 and the displacer 2200 reciprocate synchronously with mutually different phases, the refrigerant gas alternately repeats compression and expansion, and a low temperature is generated in the expansion space 2400 of the expansion cylinder 2100 every time the refrigerant gas expands. . The low temperature generated at each expansion in the expansion space 2400 is stored in the regenerator 23.
00, and generates a constant low temperature in the cooling section 2500 on the end face of the expansion cylinder 2100.
