PROBLEM TO BE SOLVED: To solve the problem wherein a conventional differential locking mechanism makes a large operation force and a large operation stroke necessary to engage an engaging member such as a pin and a dog for the differential locking, with differential side gears, etc., and as a result, turns an operating load on an operator heavier, and further may deform an operation element for transmitting the operation force to the engaging member by an excessive load. SOLUTION: A differential gear mechanism comprises a differential locking mechanism 13 in which, a clutch member 103 is provided so as to be connected to an input member 30 and so as to engage with the differential side gears 33, and the clutch member 103 is engaged with the differential side gears 33 side by being pushed by the relative rotation between the clutch member 103 and the input member 30, and the torque of the input member 30 is transmitted from the clutch member 103 to axle shafts 7 via the differential side gears 33.
