Title:

ONE−WAY CLUTCH BUILT−IN TYPE ROTATION TRANSMISSION DEVICE

Document Type and Number:

WIPO Patent Application WO/2002/101256

Kind Code:

A1

Abstract:

A one−way clutch built−in type rotation transmission device capable of preventing grease from being deteriorated earlier due to a mixing of abrasive powder of a clutch retainer (28a) into the grease for lubricating a roller clutch (10) or to an exposure of the grease to a high temperature by a frictional heat produced on slidable contact parts, wherein a suppressing piece (33) is formed on the clutch retainer (28a) at one end inner diameter side portion, a suppressing jaw part (34) is formed on the other end inner peripheral surface, and a clutch inner ring (21) is held from the axial both sides thereof by an engagement part (35) provided at the tip part of the suppressing piece (33) and the suppressing jaw part (34), whereby the axial both end faces of the clutch retainer (28a) are prevented from coming in contact slidably with the inner surfaces of a pair of jaw parts (27a, 27b) forming a portion rotated relative to the clutch retainer (28a), i.e., a clutch outer ring (25) by limiting the axial displacement of the clutch retainer (28a).
