To provide a crawler oscillation regulating device of a working vehicle which is capable of driving a crawler without resistance even when the vehicle makes a turn or travels at a high speed, capable of preventing a surface of a traveling field from being roughened, preventing the crawler from being worn in an early stage, excellent in the traveling performance, and capable of easily adjusting the oscillation angle.
The crawler oscillation regulating device has a front side stopper 30A and a rear side stopper 30B to regulate the oscillation angle of each traveling device 7 when the traveling device 7 is in an ascending posture or a descending posture on the front side or the rear side of the axis of rotation of a sprocket 2 of a pair of right and left substantially triangular crawler type traveling devices 7 with a driving sprocket 2 for a crawler provided on a vehicle body as an apex, and a longitudinally oscillating bell crank 30 which is connected to parts of the traveling devices 7 and abuts an arm part to the stoppers 30A and 30B is supported between the stoppers 30A and 30B.
