Abstract
Provided is a fluid fan clutch with excellent cooling performance capable of effectively preventing, by very simple means, a decrease in the volume of air due to backflow of cooling fan air occurring when the fan clutch is activated. The fluid fan clutch has a structure with a fan removably fixed to a housing composed of a front-side housing component (cover) and a back-side housing component (case), wherein projecting parts for preventing backflow of fan air are arranged on the back-side housing component so as to be shifted in the circumferential direction with respect to fixing projections of the front-side housing component.
