PROBLEM TO BE SOLVED: To provide a travelling device for vehicle capable of suppressing deterioration in straightness concerning travelling of a vehicle when failure occurs in at least one of a drive travelling device and a travelling control system.SOLUTION: A travelling device 10 for vehicle has a front wheel running device 20, a rear wheel running device 30, a rear wheel coupling device 40, and the running control system 50. The running control system 50 has a pair of control units 51 and on-vehicle LAN 52. The first control unit 51 mutually connects a right coupling shaft 41 and a left coupling shaft 42 with a clutch 43 when a failure occurs in a second control unit 51 or a left side drive motor 34. The second control unit 51 mutually connects a right coupling shaft 41 and left coupling shaft 42 with the clutch 43 when the failure occurs in the first control unit 51 or a right side drive motor 34. |
