Patent number: 9334903Abstract: A more durable rotation transmitting member for a coupling directly connected to shafts has: drive-side rotation transmitting cushion to which an input shaft is directly connected; and a hub to which an output shaft is directly connected. Two parallel flat surfaces are formed on the outer periphery of the front end of the input shaft, and a shaft hole receives the front end of the input shaft and is formed in the rotation transmitting cushion. Surfaces of the inner wall of the shaft hole protrude toward the axis (O) to face input shaft front end flat surfaces. Each protruding surface comprises two flat sloped surfaces extending in the direction of the axis (O). When the input shaft starts to rotate, each front end flat of the front end comes into surface contact with one of the protruding surface sloped surfaces which faces the flat surface.Type: GrantFiled: November 9, 2012Date of Patent: May 10, 2016Assignee: OILES CORPORATIONInventors: Noboru Nakagawa, Masaya Kinjyo
