を備えたことを特徴とする電磁弁。 A solenoid housing made of a magnetic material and a spool housing are connected, a fitting hole is formed in the solenoid housing, a plunger is fitted into this fitting hole so that it can move forward and backward, and the plunger is slid into the spool housing in the same direction as the fitting hole. A hole is formed, a spool operated by the plunger is slidably inserted into the sliding hole, a spring is inserted between the spool and the spool housing to bias the spool toward the plunger, and the solenoid housing is fitted with a spring that urges the spool toward the plunger. In a solenoid valve that forms a yoke and has a solenoid arranged around the solenoid housing that generates a magnetic force that attracts the plunger toward the yoke, the spool connects the sliding hole between the first space on the plunger side and the spring side. A first passage and a second passage are formed in the spool housing, and the spool is divided into a second space and communicates the first space and the second space with the outside of the spool housing. A solenoid valve comprising an annular throttle that restricts the flow of oil between the second passage and the second space between the outer periphery of the spool and the sliding hole when the valve is moved to the end.
