In a work vehicle equipped with a control mechanism, the douching prevention control mechanism is assembled to the hydraulic housing and linked to a response body that responds to the swinging of the lift arm, thereby preventing douching based on the movement of the response body. A douching prevention control device for a work vehicle, characterized in that it is configured to operate.
