プリング。 A rotary plate is attached to the tip of the rotating shaft and rotates together with the rotating shaft, and a fan is attached around it.
a case that is attached to a rotating shaft and can be rotated separately from the rotating shaft and that covers the outer periphery of the rotating plate; a viscous fluid that is accommodated within the case with a space left; and a viscous fluid provided within the case; a partition plate that partitions the inside of the case into a rear chamber containing the rotary plate and a front chamber located in front of the rear chamber, and a partition plate formed between near the peripheral edge of the rotary plate and the case or the partition plate, a viscous coupling part connected to the viscous coupling part; a pump part formed on the outer periphery of the viscous coupling part and sending viscous fluid from the rear chamber to the front chamber by relative rotation between the rotating plate and the case; and the viscous coupling part of the partition plate. a reflux hole provided on the inner periphery of the case; a valve unit mounting hole provided in front of the reflux hole on the front surface of the case; a valve unit inserted into the valve unit mounting hole from the front; The tip is approximately cylindrical, has a circumferential hole, has an elastic seal at the tip, is in close contact with the partition plate around the reflux hole, and is capable of passing viscous fluid from the front chamber to the rear chamber. a cylindrical portion; a valve provided on the tip cylindrical portion to open and close the flow passing through the tip cylindrical portion by approaching and separating from the elastic seal; and a valve provided on the base side of the valve unit to remove heat from the front of the case. A fan coupling spring comprising a temperature-sensitive actuating body part which is actuated by wax that expands upon receiving the heat and opens the valve.
