Claims

[Scope of utility model registration request]

A pair of left and right ventilation holes are formed in the clutch housing, and a weir that protrudes toward the downstream side in the clutch rotation direction is provided on the inner wall of the dust cover that covers the ventilation hole located on the upstream side in the clutch rotation direction, and communicates with the intake port. A cooling device for a vehicle clutch, characterized in that a dam is provided on the inner wall of a dust cover that covers a ventilation hole located downstream in the direction of clutch rotation, and that projects toward the upstream side in the direction of clutch rotation and communicates with the exhaust port. .
