Abstract
A hydraulic operated valve includes an electromagnetic adsorption mechanism and a steel ball. In the electromagnetic adsorption mechanism, when a current is supplied, an adsorption plate is adsorbed by a solenoid. By this adsorption, a steel ball is pressed against an outer surface of a cam disc. The outer surface of the cam disc includes two steps. When the cam disc is rotated clockwise or counterclockwise, the pressed steel ball engages the two steps. Thus, the cam disc is detented. These two steps are configured such that when the cam disc is returned to a neutral position, the adsorption plate is separated from the solenoid against the pressing of the electromagnetic adsorption mechanism. Thus, the detent state of the cam disc is canceled.
