テータコイル接続装置を提供することを目的とする。In the former case, it is necessary to prepare a stepping motor for each specification. In the latter case, the lead wire has the minimum necessary length for welding to the printed circuit board to be mounted. This is an obstacle to the motor assembly work, which inevitably reduces the production efficiency. It is an object of the present invention to provide a stator coil connecting device in a stepping motor that does not require a stepping motor to be prepared for each specification and facilitates code welding to a printed circuit board.
