Connection reliability of terminals in a movable connector is enhanced. The movable connector includes a fixed housing having an abutment receiving portion and a movable housing having an abutment portion. When a pin terminal is fitted and inserted, the abutment portion abuts on the abutment receiving portion. This prevents arcuate curved deformation of the movable housing, and restricts a movable piece of a terminal at a center portion of the movable housing from being slightly stretched from the beginning of fitting and from constantly receiving load.
