Claims (1)

[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 core provided at the center of one end of the case; a cylindrical fixed core with the tip thereof A movable iron core facing the end of the movable iron core, an output shaft that passes through the movable iron core and is fixed thereto, an output shaft whose output side passes through the fixed iron core and is elongated, and the opposite output side is shortened, and an output side end of this output shaft. An electromagnetic solenoid comprising: a slide bearing that supports a portion of the output shaft so as to be movable in an axial direction; and a slide ball bearing that supports a non-output side end portion of the output shaft so as to be movable in an axial direction.
