PURPOSE:To make a foreign substance dischargeable without entailing any adverse effect on clutch performance, by forming a discharge passage in a crankshaft or flywheel part in the axial direction, while letting a clutch output shaft end part adjoin to a foreign substance receiving part formed in the axial center part. CONSTITUTION:A discharge passage 20 is formed in a joining part between a crankshaft 10 of an engine and a flywheel 11. This discharge passage 20 is radially formed in a cranked form, and its outward end is opened to the outside of a clutch device. A disclike foreign substance receiving constituent member 21 is set up on a left end face of the flywheel 11, while an annual empty space part is formed between an inward part of this member 21 and a end face of the crankshaft 10, serving as a foreign substance receiving part 22. And, the end part of a clutch output shaft 12 is extended as far as a position adjoining to the foreign substance receiving part 22 and formed in this way. |
