Drive power transmission system
A drive power transmission system includes-a clutch hub, a clutch drum and a dry clutch. The dry clutch includes-first and second clutch plates, a friction facing and a cover member. The first clutch plate is joined to the clutch hub. The second clutch plate is joined to the clutch drum. The cover member has an external air intake hole and an external air discharge hole. These holes of the cover member are positioned such that, due to rotation of at least one of the clutch hub and the clutch drum, an air flow is generated that draws external air is through the external air intake hole and along the clutch hub to a radially inward location of reduced air pressure, then passes radially outward to a radially outward location of increased air pressure, and then passes along the clutch drum and out the external air discharge hole.
