Abstract:
The invention provides a connection structure between a coil and a bus bar attached to a stator of a motor, and the coil and the bus bar each include a lead part. At least one of the lead parts has a distal end provided with a corner cut away to be stepped to configure a stepped portion having a side surface extending substantially in parallel with a longitudinal direction of the lead part. The coil and the bus bar are connected to each other in a state where the side surface of the stepped portion of a first one of the lead parts is in contact with a second one of the lead parts.
