Abstract
A thermostat device ensures a coolant amount from a bypass passage sufficiently and excellent temperature sensitivity to the coolant temperature. The thermo-operating unit is provided with a control valve for controlling an introduced coolant amount from a first flow inlet via a radiator, corresponding to the temperature of the coolant from a second flow inlet via a bypass passage. Within the housing are provided multiple guides, which are formed extending from the second flow inlet side toward a thermo-element, are arranged intermittently around the thermo-element, and support the thermo-element slidably movable in an axial direction and coolant rectifying protrusions arranged spaced apart from the thermo-element between the guides, wherein a detoured passage for the coolant, directed from the second flow inlet side toward an outflow port, is formed by forming gaps between the guides and the coolant rectifying protrusions.
