Abstract:
To prevent a locally large load from being applied on two ends parts.
The inside diameter of a central part in the axial direction is decreased to form a thick section part 18 and a bush 16A is formed into a shape in a cross section in which diameter is increased toward two end parts. The bush 16A is pressed fitted in a pin hole 13 formed in the disc tongue part 9 of a disc 8, and a pin 15 is inserted in the inside thereof. The outer surface of the pin 15 is brought into contact with the thick section part 18 of the bush 16A. A load exerted via the pin 15 is apt to be exerted on the thick section part 18, and a stress peak is prevented from occurring at the two end parts.
