<P>PROBLEM TO BE SOLVED: To perform smooth meshing of gears when gears supported by different shafts are relatively moved to be meshed. <P>SOLUTION: To teeth 8A, 8B of an idler reverse gear 8, a teeth 8C is formed protruded to the front side of meshing starting direction with a secondary reverse gear 22, so that even when the teeth 8A, 8B and 8C are simultaneously meshed, the force pushing out each other is not generated between neighboring teeth 8A, 8B and 8C when meshing. <P>COPYRIGHT: (C)2013,JPO&INPIT |
