Abstract
It is designed that an oil pressure signal can be output by operating an operation lever in a twisting direction; a structure can be made simple and its assembly and adjustment are easy; an operation force can be reduced; and a layout is not restricted. It is also designed that when the operation lever is left free after it is twisted, it returns smoothly to the original neutral position. When the operation lever is twisted about the lever axis, the shaft supported by bearings is twisted. The twist of the shaft is converted into the movement in a direction to move the pistons by first and second levers, and the pistons are moved. When the pistons are moved, the oil pressure signal is output from the discharge ports. A disk plate is separated into a first disk plate to which the root of the operation lever is attached and a second disk plate which is tiltably supported by a tilting fulcrum. And, the first disk plate is independent of the second disk plate and twisted about the lever axis of the operation lever.
