| Zusammenfassung: | To provide a screw feeding device capable of changing easily a moving range of a movable part moving by rotation of a feed rod; and to provide a form changing toy having the screw feeding device.SOLUTION: In a screw feeding device including a feed rod having a spiral groove, a movable part (18) having a projection (18d) to be engaged with the groove, and a drive mechanism (22) for moving the movable part along the axis of the feed rod by rotating the feed rod, a plurality of feed rods (20, 21) integrated relatively movably in a telescopic type in the axial direction are provided as the feed rod, and the projection (18d) can be moved in a separating direction from the feed rod.SELECTED DRAWING: Figure 6
【課題】送り棒の回転によって移動する可動部の移動域を容易に変更させることができるねじ送り装置と、当該ねじ送り装置を有する形態変化玩具を提供すること。【解決手段】螺旋状の溝を有する送り棒と、前記溝と係合する突起(１８ｄ)を有する可動部（１８）と、前記送り棒を回転させて前記可動部を前記送り棒の軸心に沿って移動させる駆動機構（２２）とを備えたねじ送り装置において、前記送り棒として、軸心方向にテレスコープ式に相対移動可能となるように組まれた複数の前記送り棒（２０、２１）を備え、前記突起(１８ｄ)は前記送り棒に離接する方向に移動可能となっている。【選択図】図６ |
