To provide a mounting structure of a workbench in a high lift working vehicle that can reduce the number of parts and the man-hours required for assembly to regulate the elevation of the workbench to a boom side, and to compactly combine the structure to regulate the elevation of the workbench to the boom side and the parallel link mechanism.SOLUTION: A mounting structure of a workbench in a high lift working vehicle includes a parallel link mechanism 70 composed of a jib fixing member 71, an upper link member 80a, a workbench fixing member 51, and a lower link member 80b. The workbench can be moved up and down with respect to the jib fixing member 71 by the parallel link mechanism 70. A stopper member 83 is provided on at least one of the upper link member 80a and the lower link member 80b. The jib fixing member 71 is provided with regulating portions 74a and 74b that restrict the upward movement of the workbench by abutting against stopper members 83a and 83b.SELECTED DRAWING: Figure 3 【課題】ブーム側に対する作業台の上昇を規制するための部品点数及び組立作業の工数を減少させるとともに、ブーム側に対する作業台の上昇を規制するための構造と平行リンク機構とをコンパクトにまとめることができる高所作業車における作業台の取付構造を提供する。【解決手段】ジブ固定部材７１と、上部リンク部材８０ａと、作業台固定部材５１と、下部リンク部材８０ｂと、により構成される平行リンク機構７０を備え、平行リンク機構７０によってジブ固定部材７１に対して作業台が上下移動可能であり、上部リンク部材８０ａ又は下部リンク部材８０ｂの少なくとも一方にストッパ部材８３を設け、ジブ固定部材７１にストッパ部材８３ａ，８３ｂと当接することで作業台の上方への移動を規制する規制部７４ａ，７４ｂを設けた。【選択図】図３
