Abstract

A transmission mechanism includes a first gear coaxially fixed to a rotational shaft having a hollow shape, a second gear, and a third gear. The second and third gears are rotatably and coaxially disposed on an outer periphery of the rotational shaft such that the second and third gears are opposed to each other. A gear select clutch is disposed between the second and third gears, and configured to select one of a state in which the second and first gears are coupled and the third and first gears are decoupled, and a state in which the third and first gears are coupled and the second and first gears are decoupled. A clutch operation unit is configured to couple an operation shaft disposed in a hollow part of the rotational shaft to operate the gear select clutch by advancing and retreating the operation shaft in an axial direction.
