Abstract: Provided is a connector connection structure which is configured to directly connect connectors provided to casings of two devices, respectively, to each other, and which can keep sealing property of the connector connection portion. A second terminal is arranged movable with respect to a second casing, thus displacement of a first casing and the second casing with respect to each other can be absorbed by allowing the second terminal to move, thereby allowing the connectors provided respectively to the casings of the two devices to be directly connected to each other. At this time, a connector-side opening of a second housing is closed using a first housing of a first connector as a mating connector, thereby keeping sealing property of the connector connection portion while allowing the connectors provided respectively to the casings of the two devices to be directly connected to each other.
