Claims

[Scope of utility model registration request]

A case with an end member fixed to the other end to form a yoke for the magnetic path, a solenoid coil housed in the case, a fixed iron core provided at the center of one end of the case, and a solenoid coil placed at the center of the solenoid coil. A movable core facing the fixed core is provided with an output shaft made of a non-magnetic material that passes through the movable core and is fixedly extended and movably supported by bearings at both ends. An electromagnetic solenoid for hydraulic control, characterized in that a communication hole is provided that communicates from the outside with a space around the movable iron core in the case.
