PURPOSE:To prevent abnormal fan noise from being generated by incorporating a temperature sensitive body expanding and shrinking according to an oil temperature change inside a torque transmission chamber so as to check any sudden increase of fan revolution. CONSTITUTION:In the condition that the side of a circular passage 9 sinks under the oil, the oil on the oil sump 5 side naturally flows backward through the circular passage to flow down together with the oil on the torque transmission chamber 6 side and is gathered in a collecting chamber 12. And, a temperature sensitive body 13 successively expands according to next temperature increase of oil and the volume of the collecting chamber 12 is shrunk, so that the oil therein is pushed out to the torque transmission chamber 6 side. Therefore, generation of abnormal fan noise is prevented without any sudden increase of fan revolution immediately after an engine start. |
