Provided is a control device for a work vehicle that can reduce the traveling speed of the body with good followability even with a sudden increase in the load of the work device. Furthermore, a working vehicle can be satisfactorily stopped when the brake is operated without using a conventional link mechanism. In the deceleration rate setting unit 61, a deceleration rate according to whether or not the load factor of the engine exceeds the reference value is set. In the target slope plate position calculation unit 62, the traveling speed of the body is determined from the speed according to the position of the shift lever. In order to decelerate according to the deceleration rate, the target inclination plate position which is the inclination plate target position of the hydraulic pump 33 is set. Then, the current supplied to the proportional pressure reducing control valves 52 and 53 of the HST is controlled so that the position of the inclined plate of the hydraulic pump coincides with the target inclined plate position. In addition, the pair of left and right traveling apparatuses that support the gas are driven by the power output from the HST. The body is provided with the brake pedal 1141 so that operation is possible. The brake pedal 1141 is mechanically connected to the brake 1146, and the braking force by the brake 1146 acts on the traveling device according to the operation of the brake pedal 1141. In addition, when the brake pedal 1141 is operated, the operation is detected by the brake sensor. Then, when the operation of the brake pedal 1141 is detected, the position of the inclined plate of the hydraulic pump of the HST is controlled to the stop position where the fluid is not discharged from the hydraulic pump.작업 장치의 부하의 급격한 증대에 대해서도 양호한 추종성으로 기체의 주행 속도를 저감할 수 있는, 작업 차량용의 제어 장치를 제공한다. 또한, 종래의 링크 기구를 사용하지 않고, 브레이크의 작동 시에 모터를 양호하게 정지시킬 수 있는, 작업 차량을 제공한다.감속률 설정부(61)에서는, 엔진의 부하율이 기준값을 초과하고 있는지 여부에 따른 감속률이 설정되고, 목표 경사판 위치 산출부(62)에서는, 기체의 주행 속도가 시프트 레버의
