Claims

[Scope of utility model registration request]

A hub of a clutch disk that is spline-fitted to the output shaft, an annular clutch plate and a retaining plate that relatively rotatably cover the outer peripheral flange of the hub, and the clutch plate and the outer peripheral flange are elastically connected in the circumferential direction. The hub includes a torsion spring, a pair of first rubber diaphragms that seal both ends of the spline fitting part while allowing movement in the axial direction, a clutch plate, a retaining plate, and an outer peripheral flange. the outer peripheral flange is provided with square windows at a plurality of locations on the same circumference for accommodating the torsion spring so as to be expandable and contractible in the circumferential direction; The clutch plate is a clutch disk assembly having a recess facing the corner window and surrounding the torsion spring, and having an inlet for supplying lubricant into the space and an outer periphery of the clutch plate and retaining plate. A ring that seals the joint surface of the retaining plate, a sealed bearing that fits on the outer periphery of the hub and rotatably supports the inner periphery of the clutch plate, and a bearing that allows the inner periphery of the retaining plate to rotate relative to the hub. 1. A clutch disk assembly characterized in that a second rubber diaphragm is provided to seal the clutch disk in a closed state, and the inside of the clutch disk and the spline fitting portion are filled with lubricant.
