傾斜カム部を、前記床板の一端側の前記第１の作
動部によつて作動する構成とすると共に、前記床
板の他端側の第２の作動部と床板とを押上リンク
によつて連結し、該押上リンクは、該床板側また
は第２の作動部側に於いて作動方向に遊びを構成
することにより、床板の回動上昇に際しての、前
記第２の作動部による作動開始時点を、第１の作

たことを特徴とする床板の回動昇降機構。 A screw shaft is rotatably provided on a floor plate support frame that rotatably supports one end of the floor plate in a direction perpendicular to the rotational axis of the floor plate, and a first screw shaft is provided at an appropriate interval in the length direction of the screw shaft. and a second actuating part is configured to be movable by a female threaded part screwed into the screw shaft, and an inclined cam part for upward operation provided on the lower side of the floor plate is configured to be movable by a female screw part screwed into the screw shaft, and a tilted cam part for upward operation provided on the lower side of the floor plate is connected to the first actuating part on one end side of the floor plate. The second actuating part on the other end side of the floor plate and the floor plate are connected by a push-up link, and the push-up link is connected to the floor plate side or the second actuating part side. By providing play in the operating direction, the second operating section starts operating later than the first operating section when the floor plate rotates upward. Features a rotating lifting mechanism for the floorboard.
