PURPOSE:To enable to readily wind a coil by fixedly engaging the engaging parts of a rotational shaft at both ends of a core and interposing a core on the same shaft. CONSTITUTION:Both ends of a cylindrical core 2 are engaged fixedly on rotational shafts 1, 1 having cylindrical hollow holding parts 17, 17 at the ends between the shafts 1 and 1. The holding parts 17, 17 have engaging holes 17a, 17a on the holding surfaces, and both ends of the core 2 are mechanically engaged fixedly with the holes 17a, 17a coincident to the centers of the shafts 1, 1 at both ends of the core 2. Grooves 2a, 2b are formed in the same direction through the center of both ends, and a coil 3 is wound longitudinally on the outer periphery of the core 2 through the grooves 2a, 2a. Since the core 2, on which a coil is wound in parallel with the axial direction, is constructed to be interposed between the holding parts of the shaft, the coil can be readily wound. |
