PURPOSE:To aim at simplification in both disassembling and assembling operations, by attaching a clutch hub of a first clutch disc to a clutch output shaft and a clutch hub of a second clutch disc to the said clutch hub free of slide motion in an axial direction but unturnable, respectively. CONSTITUTION:Only a clutch hub 7 of a first clutch disc 6 is fitted into a main drive shaft 4 by means of spline keying. And, a clutch hub 15 of a second clutch disc 14 is fitted into an extension part 7d formed in the clutch hub 7 of the first clutch disc 6 in the same way of spline keying. Therefore, the length of a spline tooth part 4a to be formed in the main drive shaft 4 is merely enough to be such length as making the clutch hub 7 of the first clutch disc 6 attachable. In addition, in time of disassembly or assembly, the first clutch disc 6 is attached or detached to or from the main drive shaft 4 whereby setting of both these clutch discs 6 and 14 and vice versa becomes simplified. |
