Abstract

PURPOSE:To ensure a prescribed gearshift by allowing the steering lever to move by a certain amount with the hydraulic oil which is sent from the sensor cylinder working with the essential turn operation, and storing the excessive oil in the excessive oil chamber tentatively. CONSTITUTION:An essential turn operation is sensed by the sensor cylinder 103 and the cylinder sends the hydraulic oil in an amount corresponding to the turning. While a certain amount of the oil is sent at the initial stage, the hydraulic cylinder 54 works to move the steering lever 51 by a certain amount. When the lever comes to the stroke end and the inner pressure rises, the excessive oil chamber opens and connects to the oil chamber of the cylinder to store the excessive oil sent by the sensor cylinder tentatively. When the sensor cylinder comes not to work, the hydraulic oil is sent back from the excessive oil chamber contracting by the elastic force.
