Abstract
A method of manufacturing a thermo valve includes an overlaying step of overlaying a valve body onto a thermo actuator so as to cover a groove portion; and a caulking step of caulking an installing portion of the valve body onto the thermo actuator. The caulking step is performed by pressing, by use of a jig, the valve body and the thermo actuator toward an axis center in a radial direction. A pressing face of the jig has a short side portion and a long side portion longer than the short side portion. Pressing is performed with the long side portion being substantially in parallel to the axis center of the thermo actuator and the short side portion being substantially in parallel to the groove portion.
