摘要： In an electromagnetic actuator including a bearing member which slidably supports a variable core, a yoke for retaining a coil assembly by cooperation with a bottom wall of a housing is connected to the housing, and the bearing member is fitted into the yoke. A support for supporting an outward-facing flange formed at one end of the bearing member is mounted on the bottom wall, and a set spring for biasing the outward-facing flange toward the support is mounted under compression between the outward-facing flange and the first yoke. A low-friction material coating made of a fluorocarbon resin is formed on at least one of opposed sliding surfaces of the bearing member and a movable core. Thus, even if wear powder is generated between the set spring of the bearing member and a portion on which the set spring is pressed, the wear powder is prevented from entering inside the bearing member.
