Abstract
A thermo valve is configured by coupling a valve body to a thermo actuator via a coupling part. The valve body has at least two recesses extending in a peripheral direction. The thermo actuator and the valve body overlap each other in a direction of an axial centerline to cover at least one of the recesses. The coupling part is formed by at least a certain section of the overlapping portion being depressed toward the axial centerline and another section of the thermo actuator fitting in the recesses. The depression of the coupling part has a shape elongated in a longitudinal direction along the axial centerline.
