Abstract
An electromagnetic actuator includes a housing and a pair of stators cooperating with the housing to form a magnetic circuit for a solenoid. Each of the pair of stators has a tubular portion, and the tubular portions of the pair of stators have their one ends disposed in the opposed spaced relation to each other. The solenoid is mounted around the tubular portions of the pair of stators, and an armature is received in the tubular portions of the pair of stators so as to be movable along the axis of the tubular portions. The armature is supplied with a force when an electric current is applied to the solenoid. In order to keep the magnetic resistance of the magnetic circuit to a low level, one of the pair of stators is formed integrally with one end of a tubular body of the housing so that the housing and the one stator constitute a unitary member.
