PURPOSE:To prevent an inner peripheral side wedge from being displaced and improve the workability of coil assembly. CONSTITUTION:An inner peripheral side wedge 9 is bound and fixed to a coil body 1 by forming a groove 12 therein and inserting a stainless steel wire into the groove 12 and winding the same. Prior to driving of an outer peripheral side wedge 10, the inner peripheral side wedge 9 is fixed to the coil body 1 whereby any positional displacement is prevented and workability of coil assembly is improved. |
