It is the connection structure of the coil winding in the motor characterized by having the structure connected to the said conduction | electrical_connection terminal in the state made to let it go.

請求項１に記載の発明によれば、渡り線をインシュレータの外側に向けて露出した状態で引き回して導通端子に接続する構造とすることで、導通端子に接触した渡り線に対する各種の作業（例えば、治具を用いてのヒュージング加工等）が容易な構造が得られる。なお、導通端子に接触した渡り線に対する作業が容易な構造である優位性は、ヒュージング加工以外の固定方法（例えば、半田や導電性接着剤を用いた固定等）においても同様に得ることができる。つまり、請求項１に記載の発明は、ヒュージング加工以外の方法で渡り線を導通端子に接続する場合にも利用することができる。また、請求項１に記載の発明によれば、第１の導通部と第２の導通部との隙間に渡り線が挟まれることで、導通端子への渡り線の接続が行われる。この構造は、導通端子への渡り線の電気的な接触を確実なものとできる。特に、第１の導通部と第２の導通部との間に渡り線を挟んだ状態において、第２の導通部に第１の導通部の方向への圧力を加え、更にその状態で第１の導通部と第２の導通部との間に電流を流すこと行われるヒュージング加工を容易に、且つ、確実に行うことができる。つまり、ヒュージング加工を用いた渡り線の導通端子への接続に適した構造とすることができる。 According to the first aspect of the present invention, various operations are performed on the connecting wire in contact with the conducting terminal (for example, the connecting wire is connected to the conducting terminal by being routed in a state where the connecting wire is exposed toward the outside of the insulator). , A fusing process using a jig, etc.) can be obtained.
