Abstract
An electromagnetic switching valve includes: a sleeve, defining a port communicating with an oil passage; a spool, reciprocally movably disposed on a predetermined axis in the sleeve, opening and closing the port; an electromagnetic actuator, including a plunger disposed on the axis and a stator exerting magnetomotive force on the plunger; and a tubular transmission member, disposed on the axis to be interposed between the plunger and the spool and transmit driving force. The stator includes an insertion hole through which the transmission member is inserted. The transmission member includes a regulated part regulated not to deviate from a range allowing an upper end of the transmission member to be inserted into the insertion hole of the stator when the transmission member is dropped and assembled into the sleeve from a vertical direction for a lower end of the transmission member to abut against the spool integrated into the sleeve.
