摘要

A flow channel switching device (30) provided in an oil circuit to switch the oil flow channel in accordance with the temperature of the oil. The flow channel switching device (30) comprises: a thermo-valve case (31) that includes a plurality of flow passages that is communicated outside; and a cylinder (36) that is formed to move in the thermo-valve case (31) and switches the oil flow channel in accordance with the temperature of the oil. The cylinder (36) moves to a predetermined position and is fixed by means of an external member (139) when the fluid at a low temperature is fed into the fluid circuit.
