Abstract:
To properly fit a sleeve tooth part and a gear tooth part to each other, and to reduce friction.SOLUTION: A transmission 10 includes: a drive mechanism 15 for moving sleeves 51, 52 and 53 in a rotation axis Xa direction by imparting drive forces thereto, and switching engagement and disengagement of a sleeve tooth part 56 and a gear tooth part 26; and a drive control part 96 for controlling movement of the sleeves 51, 52 and 53 in the rotation axis Xa direction by controlling drive forces FA imparted to the sleeves 51, 52 and 53 by the drive mechanism 15. When a collision between the sleeve tooth part 56 and the gear tooth part 26 is detected by a collision detection part 94 when moving the sleeves to sides of gear-change gears 21, 22 and 23, the drive control part 96 increases the drive forces Fa, and energizes the sleeve tooth part 56 to the sides of the gear-change gears 21, 22 and 23 by a spring member 70a.SELECTED DRAWING: Figure 1
