The aim of the present invention is to expel to the outside the abrasion powder generated between pressure-contacting clutch plates through friction facings by placing said powder into axial direction airflow. A hybrid power transmission system wherein a dry multi-plate clutch (7) for cutting the transmission of drive power positioned within a sealed space is provided with a drive plate (71), a drive plate (72), a friction facing (73) and a front cover (60). The drive plate (71) is splined to a clutch hub (3). The drive plate (72) is splined to a clutch drum (6). The front cover (60) comprises an external air intake hole (66) for introducing external air into the sealed space, and an external air exhaust hole (67) for expelling airflow from within the sealed space to the outside. The front cover (60) positioned on the clutch side surface is perforated on the inner diameter side of both clutch plates (71, 72) in the axial direction to provide the air intake hole (66) and is perforated on the outer diameter side of both clutch plates (71, 72) in the axial direction to provide the air intake hole (67). |
