Patent number: 6814581Abstract: A connection body (41), of a connector for a towing vehicle, to be connected to a wire harness of a to-be-towed object and a connection body (42) of the connector to be connected to a wire harness of a towing vehicle body are approximately cylindrical. Terminals (32, 33) inside the connection bodies (41, 42) are composed of a common metal piece (31). The connector is connected to a wire harness (35) of the towing vehicle body not by using an exclusive cylindrical connector but by directly connecting a core wire to the terminal (32).
