Abstract

PURPOSE:To eliminate the operation of separately filling oil between a reduction gear shaft and a gear movably engaged with the shaft at an assembling time by immersing lubricating oil therebetween. CONSTITUTION:An axial hole 81 for communicating with oil reserving gaps 13, 14 between shaft supporting plates 9, 10 and oil reserving plates 11, 12 is formed at a reduction gear shaft 8A, and a slip port 82 for communicating between the hole 81 and a gap on the outer periphery of the shaft 8A, i.e., between the shaft 8A and a reduction gear 7 is formed. Thus, lubricating oil in the gaps 13, 14 is fed to the gap between the shaft 8A and the gear 7 through the axial hole 81 and the port 82, thereby lubricating therebetween.
