ABSTRACT:
A differential locking section is provided between a pair of output members that respectively mesh with a pair of gears. Since, at least one of the output members is composed of a first output shaft member that meshes with the gear, and a second output shaft member rotatable with and axially movable relative to the first output shaft member, differential locking can be effected by axially moving only the second output shaft member, while the mesh between the first output shaft member and one of gears is leaving.
