To provide a maneuverable slide and swing-wing system in which a connection member can engaged with each one slide and swing wing by a connection piece at the wing side arranged on a revolving shaft of the slide and swing wing and a structure in which slide of the slide and swing wing is locked when the wing is revolved is simplified so as to be easily assembled and highly stabilized.

When a connecting piece 8 is sectioned in the crosswise direction of the revolving shaft 4, since the connecting piece 8 has a circular form having an incision 14 at one side of a plane element, the length measured crosswise of the connecting piece from the revolving shaft in the plane element is smaller than the length at the opposite side of the revolving shaft toward the incision and further smaller than the length measured in both directions along the plane element.
