PROBLEM TO BE SOLVED: To provide a lifter which can be utilized as means for changing a support height of an article to be conveyed, placed on a conveying travelling body and conveyed.SOLUTION: A lifter is so constructed that: two lifting drive chains 30a and 30b bendable only to one side from a linear state are provided corresponding to a pair of right and left cross link mechanisms 13A and 13B which instruct a cradle 23 supporting a work support base 13 to a horizontal position; in each of the lifting drive chains 30a and 30b, a part between the cradle 23 supporting the support base 13 and a drive tooth ring 32 at a base 12 side is arranged in a vertical direction linear state outside the front-back direction of an end of position fixing support shafts 19 and 24 of the cross link mechanisms 13A and 13B; and a part horizontally extending from the drive tooth ring 32 each of the lifting drive chains 30a and 30b extends horizontally in the front-back direction to the opposite side to a side of the cross link mechanisms 13A and 13B.SELECTED DRAWING: Figure 1
【課題】搬送用走行体上に載置されて搬送される被搬送物の支持高さを変更する手段として活用出来るリフターを提供する。【解決手段】直線状態から片側にのみ屈曲可能な昇降駆動用チエン30a,30bが、ワーク支持台13を支持する架台23を水平姿勢に指示する左右一対のクロスリンク機構13A,13Bそれぞれに対応して2本設けられ、各昇降駆動用チエン30a,30bは、ワーク支持台13を支持する架台23と基台12側の駆動歯輪32との間の部分が、各クロスリンク機構13A,13Bの位置固定支軸19,24のある側の端部の前後方向の外側で上下方向直線状に配置されると共に、各昇降駆動用チエン30a,30bの駆動歯輪32から水平に延出する部分は、各クロスリンク機構13A,13Bのある側とは反対側へ前後方向水平に延出する構成。【選択図】図1
