Abstract
Provided is an electromagnetic valve capable of stabilizing an injection amount even when injection is performed while an intermediate member continues to be displaced after valve closing and returns to a closed valve standby state. For that purpose, a valve bodyopens or closes a flow path. A movable iron coremoves the valve bodyin a valve opening direction using a magnetic attraction force. An intermediate memberforms a preliminary stroke gap (g) between the movable iron coreand the valve bodyin a closed valve state. A stopper portioncollides with the intermediate memberwhen the intermediate membermoves in a direction in which the preliminary stroke gap (g) is reduced.
