Beschreibung
Zusammenfassung:	An electromagnetic switching valve includes: a sleeve, defining a port communicating with an oil passage; a spool, reciprocally movably disposed on an axis in the sleeve, opening and closing the port; an electromagnetic actuator, including a plunger disposed on the axis and a stator; a transmission member interposed between the plunger and the spool; and an energizing spring, energizing the spool toward the plunger. The transmission member includes a first abutting part of a convex shape tiltably abutting against a receiving recess of the plunger; a second abutting part of a concave shape abutting against a convex end of the spool; and an outer peripheral wall that, in a state of being deviated from the axis and inclined, regulates the inclination by contacting an inner peripheral surface of the sleeve or the stator.
