Patent number: 7370741Abstract: A pair of ball bearings 19, 19 and a roller clutch 20 are provided between the outer peripheral surface of the sleeve 18 fitted and fixed onto the rotating drive shaft of a starter motor and the inner peripheral surface of the pulley element 17 around which an endless belt for starting an engine extends. The roller clutch 20 has a concave section 32 on the inner peripheral surface of the clutch outer ring 30 to define a cam surface 31. After the engine is started, the rollers 33, 33 move toward the bottom of the concave section 32 against the resilient force of the springs 40. And, the rolling contact surface of the rollers 33, 33 is separated from the outer peripheral surface of the clutch inner ring 29. Consequently, the friction heat which would be produced after the engine start is suppressed, and a structure having an excellent durability as a unit for starting the engine of the idling-stop vehicle is realized.Type: GrantFiled: January 17, 2003Date of Patent: May 13, 2008Assignee: NSK Ltd.Inventors: Yuji Shimomura, Daisuke Fujimori
