Title: Starter
Inventor: NIIMI MASAMI

Filed: 2008-12-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a starter that can attenuate a gear noise generated when a pinion gear 5 collides and meshes with a ring gear, and can improve an abrasion resistance of the pinion gear 5.  <P>SOLUTION: For example, the pinion gear 5 is formed by joining a plurality of laminated steel plates 50 each having a thickness t=2 mm, in the axial direction by welding or the like. Each of the steel plates 50 is formed with a gear teeth part of the pinion gear 5 on an outer diameter side. The welding section for joining the steel plates 50 together is set at a position where it does not cover the gear teeth part of the pinion gear 5 (for example, an inner diameter side of the gear teeth part of the pinion gear 5), and the gear teeth part is not joined. Thereby, when the pinion gear 5 collides with the ring gear, each of the steel plates 50 can bend by a very small amount to produce frictions between the steel plates 50. As a result, an impact force caused by the collision between the pinion gear 5 and the ring gear is reduced by the friction action between the steel plates 50, thereby the impact noise generated when both the gears collide can be attenuated.  <P>COPYRIGHT: (C)2010,JPO&INPIT
