Abstract: Through a housing of an electric motor, an output shaft attached to a rotor penetrates. In this housing, an air tightness test hole of the electric motor which communicates with internal space of the electric space formed with the housing and a stator is formed. Further, an oil seal which blocks aeration between the internal space and an outside of the electric motor is attached to this housing.

Abstract: A motor structure capable of easily conserving space, being low cost and having few components, while utilizing a connecting method using conductive caulking. In a motor structure, a winding wire is wound onto a stator core, a terminal member is attached to one end of the winding wire by conductive caulking, and the terminal member is directly connected to a connector by soldering. The terminal member has a wire receiving portion which receives one end of each of at least one winding wire, and a connecting portion which may be directly connected to the connector or a terminal block by soldering. The wire receiving portion is a generally cylindrical member, and the connecting portion is a rod member which may be inserted into a connecting hole of the connector.
