An oil port of an oil passage in communication with a reservoir chamber in a position assuming a neutral position of a piston stroke region is formed in a cylinder body of the control cylinder, a piston within the cylinder body is always biased from both directions thereof by means of a pair of springs, and a locked state of the control cylinder is promptly attained always in a complete neutral position.
