PROBLEM TO BE SOLVED: To solve the problem that a hydraulic actuator for an automatic brake is disposed separately from an actuator of a cam type brake in a braking device provided on a rear axle of a tractor, and the required space and the parts number are increased. SOLUTION: In a rear axle of a tractor to transmit the power to a rear axle via a reduction gear from a reduction shaft extending from a differential device to right and left sides, friction disks 45 and 46 of a brake are disposed on the reduction shaft 22, the friction disks 45 and 46 can be braked by an actuator 43, and the actuator 43 is disposed between the reduction shaft 22 and a rear axle case 21 so that the rear axle is braked by operating the actuator 43 operated by the hydraulic pressure generated by the cam operation or the steering wheel operation connected to a brake pedal.
