To provide a hydraulic wheel lifting device for a working type working vehicle with a low cost and a compact size controlling an attitude of a vehicle body by ascending/descending a rear wheel by a hydraulic cylinder and facilitating a direction change of the vehicle body by jumping up a front wheel.

The hydraulic wheel lifting device for a walking type working vehicle is provided with a pitching hydraulic cylinder 21 for changing height of a vehicle body from ground surface by simultaneously lifting right and left rear wheels; and a jumping up hydraulic cylinder 23 for leaving right and left front wheels from a ground surface by simultaneously lifting them. A hydraulic circuit for the pitching hydraulic cylinder 21 is constituted such that an oil fed to the pitching hydraulic cylinder 21 can be fed to the jumping up hydraulic cylinder 23 when the pitching hydraulic cylinder 21 arrives at a predetermined position at a raising side of the vehicle body.
