A charging connector connecting device includes a cover that is movable between a closed position at which a connecting portion is closed and an open position at which the connecting portion is opened so that a second charging connector can be connected to the connecting portion; an elastic member that applies a biasing force to the cover so that the cover is positioned at an initial position between the closed position and the open position; and a pressing member configured to move with insertion of a first charging connector into the connecting portion so as to press the cover positioned at the initial position to thereby move the cover to the closed position.
