特徴とする懸架ばねロツク装置。In the suspension spring locking device, a piston rond side oil chamber of a hydraulic cylinder interposed between a vehicle frame and a wheel is connected to a hydraulic power source via a switching valve to lock a suspension spring that suspends the wheel. A suspension characterized in that a drive circuit for the switching valve is provided with a neutral detection means that allows the switching valve to connect the oil pressure source to the piston rod side oil chamber of the hydraulic cylinder when the neutral state of the transmission is detected. Spring lock device.
