１本レバーによる操縦装置。 The forward, reverse, and turning operations by one manual lever are transmitted to the selected lever member, and the movement of the lever member is linked to the control levers of the left and right hydraulically driven pumps to control the discharge amount of both pumps. In a one-lever control device for controlling, a pair of lever members for forward movement and a reverse movement are arranged in series so as to be symmetrical about an axis provided below the manual lever, Each of the lever members is movable up and down, and during a forward operation, the lever member is raised or lowered, and this movement operates the control levers of both pumps in a direction away from the neutral position, and during a turning operation during forward movement, the lever member is raised or lowered. A one-lever operating device characterized in that one of a pair of lever parts is moved in the opposite direction to the other to operate only the control lever of the pump on the rotating side in the returning direction.
