<p><P>PROBLEM TO BE SOLVED: To provide a method of connecting a seat belt winding motor capable of easily and quickly performing solid resistance welding having high non-destructive strength in an even metal structure without requiring skill in the work, capable of preventing disorder in winding condition of a structural conductor narrow wire of an electric wire due to uneven melting of the electric wire near the resistance welding part, and capable of finishing well in appearance near the resistance welding part of the electric wire without lowering strength of the electric wire itself. <P>SOLUTION: When a width at a right angle against the axial direction of a contact recessed surface 7 formed in an upper electrode 6 in the axial direction of an electric wire 3 is L and a vertical distance between a contact surface 7a of the upper electrode 6 with a motor terminal 2 and the deepest part of the contact recessed surface 7 is H, H and L are formed to satisfy a formula H/L=0.2-0.4. Further, the contact recessed surface 7 is arranged to be brought in contact with a release surface 3b over a resistance welding part 15 of the electric wire 3 to the motor terminal 2 in the axial direction of the electric wire 3, and formed to be gradually separated from the release surface 3b in the outside of both ends of the resistance welding part 15. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
