持装置。Two wheels, one for the left wheel and one for the right wheel, connected in tandem to the engine.
A skid-steering industrial vehicle equipped with variable displacement hydraulic pumps, which travels and steers the vehicle by individually rotating the trunnion levers that are attached to the trunnion shafts of each hydraulic pump so that they rotate together. A rotary lever rotatably mounted on the trunnion shaft or on the same axis as the trunnion shaft is made to be able to come into contact with an adjustable stopper for defining a neutral position provided on the fixed side of the pump body, and the rotary lever is always urged to contact the stopper by the first return spring, and the rotary lever is brought into contact with the trunnion lever in the rotational direction given by the first return spring, thereby causing the trunnion lever to Neutral maintenance of steering in a skid steering type industrial vehicle, characterized in that a retaining piece for regulating the neutral position is provided, and the trunnion lever is constantly biased by a second return spring so as to come into contact with the retaining piece. Device.
