Abstract

PURPOSE:To reduce the weight of the captioned item by providing an armature supporter which is bonded by non-magnetic material or composed in an integrated form. CONSTITUTION:An armature 8 holding a suitable gap with a longitudinally extended end portion of a drive member 2 holding and engaging with one end of a coil spring 7 having another end fitted into a notched portion formed on a circumference of a first input portion 6 is attracted through a permanent magnet 13 and accommodated between supporters constructed by armature supporters 9, 11 and non-magnetic armature cover 12. Consequently, when current flows, the armature 8 is attracted to the drive member 2 against the magnet 13. Because the cover 12 is non-magnetic, the supporter 9 is not affected magnetically. Because the supporters 9, 11 a yoke 10, a cover 12 and the magnet 13 can be made integrally, synthetic resin of low specific weight can be used.
