A twin clutch apparatus includes a first clutch, a second clutch, and a clutch outer member shared by the first and second clutches. The clutch outer member has groove portions formed therein having a width that gradually increases towards an open-end side of the clutch outer member. A width of each protruding portion formed in friction plates of the second clutch disposed towards the open-end side of the clutch outer member is greater than a width of each protruding portion formed in friction plates of the first clutch disposed towards a closed-end side of the clutch outer member. The twin clutch apparatus, during operation thereof, is operable to control a clearance between groove portions of the clutch outer member and protruding portions of friction plates within a desirable range, to reduce force and sound produced by an impact between the clutch outer member and the friction plates.
