Filed: 1983-11-10
Abstract: PURPOSE:To prevent the generation of noise of a gear by providing an idler gear capable of freely sliding acially and putting out the idler gear from the engagement with a backward driving gear and a backward intermediate gear during forward driving. CONSTITUTION:An idler gear 29 is capable of sliding axially, and during foward driving, the idler gear 29 is moved to a non-operation position to be put out from the engagement with a backward driving gear 22 and a backward intermediate gear.
