To prevent damage from being caused in a movable piece caused by inclination of the movable housing of a floating connector. Providing an inclined piece portion in a movable piece of a plug terminal of a plug connector from a middle side to an outer edge side of a bottom wall portion of a movable housing, the inclined piece portion obliquely extending so as to gradually be distanced away form a substrate. Since the inclined piece portion is distanced away from the substrate by the amount of inclination of the inclined piece portion when the movable housing is inclined, a risk of the movable piece impinging against the substrate can be reduced.
