PROBLEM TO BE SOLVED: To provide a dust discharging structure of a clutch capable of preventing the sticking of abrasion powder even if the abrasion powder cannot be released to air and suppressing the defective operation of the clutch and the progress of the abrasion of a spline part. SOLUTION: The dust discharging structure of the clutch includes a first clutch CL1 that axially presses a driven plate 11 and a drive plate 12 by a hydraulic actuator 13 to provide a fastened state that the plates 11, 12 are axially pressed. Abrasion powder discharging guide grooves 11b, 12b for guiding abrasion powder in the outer radial direction are formed on the driven plate 11 and the drive plate 12 in the outer radial direction. A guide taper surface 24b that is gradually displaced axially in the outer diameter direction is formed at an outer plate support 24 that supports the outer circumference of the driven plate 11. A collecting space 8 for collecting the abrasion powder is formed at a drying chamber 55b connected to an end of the guide taper surface 24b. COPYRIGHT: (C)2011,JPO&INPIT
