PULLEY DEVICE WITH BUILT-IN ONE-WAY CLUTCH

摘要

PROBLEM TO BE SOLVED: To prevent axial displacement of a clutch retainer constituting a one-way clutch with eliminating elements causing high cost, e.g. dispensing with troublesome machining. SOLUTION: In this device, ball bearings are used as support bearings 9a, 9a provided in both sides of one-way clutch 10a. Both axial end faces of a clutch retainers 20 and side faces of rim parts 18, 18 of respective bearing retainers 17, 17 installed in the respective support bearings 9a, 9a are closely faced each other. Both the rim parts 18, 18 prevent axial displacement of the clutch retainer 20.
