Abstract
A valve device with fail-safe mechanism capable of improved production efficiency includes a valve element, a valve element housing, a third communication port provided in the valve element housing, and a fail-safe mechanism. The fail-safe mechanism includes a thermo-element and an element housing that houses the thermo-element. The element housing has a large-diameter housing, a small-diameter housing portion that accommodates the thermo-element, and a step. A valve element communicating portion communicating with the valve element housing is provided to the small-diameter housing portion. The fail-safe mechanism includes a valve plate member for closing the step and a coil spring that biases the valve plate member. A third adapter provided to the third communication port is provided with a through-hole that enables the large-diameter housing portion and the third communication port to communicate with each other.
