PROBLEM TO BE SOLVED: To provide a coil structure of a rotary motor, enabling high output of the rotary motor by easily winding coils in which an element wire is wound regularly around each of salient poles of a stator. SOLUTION: The coil mechanism of the rotary motor is provided with: a cover member made of an insulating material for keeping an insulating state with a circular stator having a plurality of salient poles; and a coil C formed by winding an element wire therearound and wound around each of the salient poles via the cover member. The cover member is configured as a circular structure in which a plurality of bobbins 2 used to wind a coil around each salient pole of the stator are coupled, each of the bobbins is provided with a plurality of cylindrical portions 22 for individually covering the surface of each salient pole in a state where the element wire is wound, and flanges 24i, 24o protruding from inside/outside diameter end portions 22i, 22o of the cylindrical portion, and a plate member 4 formed independently from the bobbin is provided on both ends of a rotary axis direction of the cylindrical portion of the bobbin. In the plate member, a plurality of groove portions 4a, 4b, 4c for guiding and arranging the element wire 10 during winding are formed along the winding direction of the element wire.
