A shift mechanism includes a second driven gear, a first conical roller bearing and a second conical roller bearing, a biasing member, a first spacer, and a nut. The second driven gear meshes with a driving gear. The first and second conical roller bearings are disposed on an outer periphery of a tubular portion of the second driven gear in directions opposite from one another. The biasing member biases one of inner or outer races of the first or second conical roller bearings in directions separate from one another. The first spacer maintains a distance between the other ones. The nut holds the first conical roller bearing and the second conical roller bearing to the tubular portion of the second driven gear. One of the inner or outer races of the first and second conical roller bearings are relatively displaceable in an axial direction.
