PROBLEM TO BE SOLVED: To miniaturize a device itself by a simple control mechanism by forming an oil feeding mechanism in a position close to a cooling water passage and using a temperature sensing member changed by the temperature of the cooling water passage as a component member. SOLUTION: An oil feeding mechanism 9 is formed of a thermowax 7 which is arranged in a lower part in a case and changed by the temperature of a cooling water passage 11, an elastic coat 8, and a storage chamber 12. The elastic coat 8 has the circumferential end part fixed to the inner wall of the storage cheer 12 to isolate upper silicon oil from the lower thermowax in the storage chamber 12. The storage chamber 12 and the case are communicated with each other by an oil passage 10 extended vertically. This constitution can form the oil feeding mechanism 9 of the temperature sensing member acting by sensing the cooling water temperature, miniaturize the device itself, and reduce the cost. |
