PROBLEM TO BE SOLVED: To provide a loader capable of reducing a burden on a worker by carrying up a load from a floor surface even in the case where an inclination angle of a control lever is small.SOLUTION: A loader lifting device 3 of the loader is supported from a position where a support shaft 31a2 of a crank body 31 which is inclined by a control lever 31a1, is connected with one end of a crank connection part 32a1. A rotating operation of the crank body is transmitted through the crank connection part to a substantially egg-shaped cam body 32a. While horizontally moving the cam body in response to the operation of the crank connection part, a rear part 32a1 of the cam body is rotated and until a front part 32a2 of the cam body is moved on an elliptic track and brought into a substantially rising state in response to the rotation of the rear part of the cam body, a cam connection part 32b connected to the front part of the cam body is moved in an oblique direction.
【課題】操作レバーの傾倒角度が小さくても荷物を床面から持ち上げて作業者の負担を軽減することができるローダを提供する。【解決手段】ローダのローダ昇降装置3は、操作レバー31a1で傾倒するクランク本体31の支持軸31a2とクランク連結部32a1の一端が接続された位置とは離れており、このクランク本体の回動動作がこのクランク連結部を介して略卵型形状のカム本体32aに伝わり、このカム本体がこのクランク連結部の動作に応じて水平移動しながらカム本体後部32a1が回動し、このカム本体後部の回動に応じてカム本体前部32a2が楕円軌道上を移動して略起立状態となるまで、このカム本体前部に接続されたカム連結部32bが斜め方向に移動する。【選択図】図1
