Abstract

PURPOSE: To make the promotion for a thinner type of the movement, by means of providing a protecting elastic unit at the outside of a coil to prevent the coil from deformation or damage caused by an exteranl force.
CONSTITUTION: Around the periphery of a magnetic core 1, is wound a coil 2. Making a contact with one face in the outsides of said coil, is arranged a first coil protecting elastic unit 3 made of polyacetal resins that touches a base plate 5 to fill up an air gap between the coil 2 and the base plate 5. Further touching a face, in the outsides of coil 2, facing against the elastic unit 3, is arranged a second coil protecting elastic unit 4 made of silicone rubbers that fills up an air space between the base plate 5, a shielding plate 6 and the coil 2. Consequently, absorption of a shock can prevent the coil core 1 or the coil 2 from deformation or damage caused by an external force, with a facilitation of the work made capable for the movement into thin type.
