る切換弁。[Claim for Utility Model Registration] A sensor yoke is attached to one end of the spool, and a cylindrical body containing the sensor yoke so as to be movable back and forth is installed. A Hall element is provided outside the cylindrical body to prevent oil in which the sensor yoke, which detects the amount of displacement of the spool by the Hall element, from leaking into the installation space of the Hall element. switching valve.
