In the above-described embodiment, the terminal fittings 20 and 12 are bolted together through the internal space 34 of the connector 2. However, the connector mounting portion 10 is provided with a hole communicating with the receiving hole 13, and the terminal fitting 20, 12 may be bolted together (Japanese Patent Laid-Open No. 11-126661, a conventional example). Moreover, in embodiment mentioned above, although the connector 2 connected to the motor was attached to the connector attachment part 10 of an inverter, the connector 2 connected to electronic devices other than a motor is attached to the connector attachment part 10 other than an inverter. Of course, it may be attached.
The above-described embodiments are merely representative examples of the present invention, and the present invention is not limited to the above-described embodiments. That is, various modifications can be made without departing from the scope of the present invention.
