PROBLEM TO BE SOLVED: To prevent a delay of response in the posture control due to existence of ON delay in the tilting signal detected by a tilting signal detecting means, and to prevent the instability of the posture control based on the tilting signal corresponding to the fine vibration in the normal work when steering for turning movement in a working vehicle. SOLUTION: Posture control of a working vehicle is performed on the basis of the tilting signal value (b) obtained by eliminating the preset frequency component from the tilting signal (a), which is obtained by detecting the tilting angle of a machine body with a tilting detecting means 1, with a signal processing unit 3. In this working vehicle, a tilting control device performs the posture control on the basis of the tilting signal value (b) without providing ON delay, and in the case of normal turning movement, posture control is performed on the basis of the tilting signal value (c) of a frequency component lower than that of the normal work with processing by plural signal processing unit 3.
