Abstract

PURPOSE: To prevent the generation of vibration noises, and to obviate the deformation and failure of winding, by positively supporting the winding to the contraction of a coil and thrust in the winding axial direction of an induction electric appliance.
CONSTITUTION: When winding 5 contracts, a piston 13 is downward pushed by means of a spring 16, a winding clamping portion material 20 drops, a push condition is maintained and slackness is not formed in the winding 5. When great electromagnetic force is generated in the winding 5 due to external short-circuit accidents, etc., thrust in the axial direction acts and the piston 13 is pushed up, balls 15 function as wedge action and the rise of the piston is prevented because a semi- circular groove 13b has an inclined plane. A core 1 is clamped by means of fittings 2, this clamping unit 12 is mounted to the fittings 2 and a lower end of the piston 13 contacts with the winding clamping portion material 20. This constitution improves the reliability of the clamping of the winding.
