To provide a cargo receiving table lifting device which enables reduction of operational force that a worker needs in the middle of closing operation and also enables reduction of operational force when a cargo receiving table is opened from an opening position after the closing operation ends.SOLUTION: A cargo receiving table lifting device includes a link 34 which connects a lifting mechanism B which moves up or down a cargo receiving table 2 with a torsion bar 7, which may bias the cargo receiving table 2 with a biasing force generated by twisting according to an angle of rotation related to opening or closing, and changes its attitude according to the rotation. The link 34 works in conjunction with closing operation of the cargo receiving table 2. In an early stage of the closing operation, a torsion bar connection part 34D, which connects an end part of the torsion bar 7, is rotated so as to inhibit twisting of the torsion bar 7 from being eliminated in conjunction with the closing operation. In a later stage of the closing operation, the torsion bar connection part 34D is rotated so as to facilitate elimination of twisting of the torsion bar 7 in conjunction with the closing operation.SELECTED DRAWING: Figure 4

    【課題】作業員に要求される、閉じ動作の途中での操作力を軽減するとともに、閉じ動作が終了した後で、次に、開き位置から荷受台を開いていく際の操作力も軽減できる荷受台昇降装置を提供する。【解決手段】荷受台2を昇降させる昇降機構Bと、前記荷受台2を開閉に係る回動の角度に応じたねじりにより生じる付勢力で付勢可能なトーションバー7とを連結し、前記回動に応じて姿勢が変化するリンク34と、を備え、前記リンク34は、前記荷受台2の閉じ動作に連動し、前記閉じ動作の前期では、前記閉じ動作に伴う前記トーションバー7のねじり解消を抑制するように、前記トーションバー7の端部を連結するトーションバー連結部34Dを回動させ、前記閉じ動作の後期では、前記閉じ動作に伴う前記トーションバー7のねじり解消を促進させるように、前記トーションバー連結部34Dを回動させる。【選択図】図4
