The present invention is a structure of an electrical connection portion formed by thermal bonding of a terminal of a current-carrying component of a motor and a winding wire . The terminal includes a lock portion positioned on a base end side and a fusion portion positioned on a distal end side. The winding wire includes a binding portion wound around the lock portion and has a one end portion coupled to a molten ball generated at the fusion portion ; and a coupling wire portion tightly stretched from a main winding wire portion of the motor disposed in a wound state and continuous to the other end portion of the binding portion . The one end portion of the binding portion is in a state where tension pulling the coupling wire portion to the main winding wire portion side does not act. 1. A structure of an electrical connection portion formed by thermal bonding of a terminal of a current-carrying component of a motor and a winding wire , wherein: a lock portion positioned on a base end side; and', 'a fusion portion positioned on a distal end side,, 'the terminal includes a binding portion wound around the lock portion, the binding portion having one end portion coupled to a molten ball generated at the fusion portion; and', 'a coupling wire portion tightly stretched from a main winding wire portion of the motor disposed in a wound state and continuous to the other end portion of the binding portion, and, 'the winding wire includesthe one end portion of the binding portion is in a state where tension pulling the coupling wire portion to the main winding wire portion side does not act.2. The structure of the electrical connection portion according to claim 1 , whereinthe binding portion after the thermal bonding is in a state in which a bearing power is acting to retain the wound state to the lock portion, the bearing power being larger than the tension.3. The structure of the electrical connection portion according to claim 2 , whereinthe terminal includes a ...
