Abstract

PURPOSE: To prevent rear shorts while eliminating the dispersion of the dimensions of a cylindrical coil after pressing, by thickly forming thickness near an end surface of the side that couples the winding-starting and winding-ending strands of this armature consisting of the coil.
CONSTITUTION: Coil strands near a coupling portion 2 of the winding-starting and winding-ending strands of a cylindrical coil of this armature 1 consisting of the coil are made up in shapes that are protruded to the inside. The armature 1 is mounted to an end portion of a mandrel, and stepped concave portions are installed to the mandrel so that the coupling portion 2 not be crushed by means of the mandrel when molding the coil by smashing a coil body by means of press working by means of dice disposed around the armature so as to cover an outer, cylindrical surface of the coil. Thus, the dispersion of the weight of the coil after winding the coil is absorbed by means of portions β near the end portion while the rear shorts of the coupling portion 2 are eliminated, and the dimensions of an outer diameter of the coil can be stabilized.
