<p>PROBLEM TO BE SOLVED: To obtain a solenoid type oscillating actuator in which attraction of the armature can be enhanced, without increasing the magnetomotive force of a coil. SOLUTION: Two pole contact faces are constituted of the pole contact parts 5a, 6a which have hooked cross-section for attracting an armature 1. Under a standby state where the armature 1 faces the pole contact parts 5a, 6a via an air gap, a large contact area is formed by the pole contact face and the magnetic reluctance is reduced. In exciting a coil, the armature 1 is attracted only to the pole contact face in order to concentrate the flux, thus increasing attraction under respective states.</p> |
