PURPOSE:To easily perform quick operation of speed change, by longitudinally swinging a speed change lever and switching gears in a subspeed changer simultaneously by laterally swinging the speed change lever stepwise then successively switching to mesh gears in a main speed changer. CONSTITUTION:A speed change lever 101 is laterally swung about a spherical seat 102 as a center to switch meshing gears in a main speed changer, while the speed change lever 101 is longitudinally swung to switch meshing gears in a subspeed changer. A gear 5a is rotatably supported to an input shaft 1, then a gear 12a meshed to the gear 5a and a gear 12b meshed to a gear 5b are rotatably coupled to a subshaft 10 respectively, thus the subspeed changer is constituted. While gears 33, 27, 28 are rotatably supported to a main shaft 31, then a gear 17 meshed to the gear 33, gear 23 meshed to the gear 28, and a gear 18 meshed to the gear 27 through a gear 21, are rotatably coupled to the subshaft 10, thus the main speed changer is constituted. |
