1. A connector connection structure, including:
an internal connector positioned inside a casing,
an external connector positioned outside the casing, and
an electronic control unit electrically connected between the external connector and the internal connector,
wherein the electronic control unit includes a main part that opposes an opening formed in the casing when the internal connector is connected thereto, and a first conductive connection portion and a second conductive connection portion provided on either end of the main part and configured to be connected to the internal connector and the external connector, respectively, and
a first seal member is provided on an outer periphery of the main part, the first seal member closing the opening when the external connector is not connected to the electronic control unit, and the internal connector is connected to the electronic control unit
wherein the external connector is provided with a tubular portion having a part opposing the opening in a state where the electronic control unit is connected to the internal connector and the external connector, and
the first seal member is configured to be selectively in a first state where the first seal member abuts against the inner peripheral surface of the opening to provide a seal between the casing and the electronic control unit when the electronic control unit is connected to the internal connector and the electronic control unit is not connected to the external connector, and a second state where the first seal member abuts against the inner peripheral surface of the tubular portion to provide a seal between the electronic control unit and the external connector when the electronic control unit is connected to the external connector.
