PROBLEM TO BE SOLVED: To provide a loader that can operate a cargo more safely and more easily.SOLUTION: The loader comprises: a carriage that has a running roller and can run along a groove-shape rail formed on a floor surface; a cargo receiving member that is placed on the carriage and has an inclined cam for elevating at a lower part thereof; and an elevation driving mechanism that is fastened tightly to one end of the carriage and elevates the cargo receiving member with respect to the carriage. The elevation driving mechanism comprises: a bevel gear mechanism that has an input rotary shaft to be rotated by rotation driving from the outside and an output rotary shaft which crosses the input rotary shaft; a ball screw mechanism that has a screw shaft connected to the output rotary shaft and a nut which moves linearly along the screw shaft; and a pulling-up link member, one end of which is connected to the nut and the other end of which is connected to the cargo receiving member.SELECTED DRAWING: Figure 1
【課題】より安全に、かつより容易に荷物を操作することができるローダを提供する。【解決手段】ローダは、走行ローラを有し、床面に形成された溝状のレールに沿って走行可能な台車と、この台車に載設され、下部に昇降用傾斜カムを有する荷受部材と、台車の一端に固着されて荷受部材を台車に対して昇降させる昇降駆動機構とを備えている。昇降駆動機構は、外部からの回転駆動によって回転する入力回転軸及びこの入力回転軸に直交する出力回転軸を有するベベルギヤ機構と、この出力回転軸に連結されたネジ軸及びネジ軸に沿って直線に移動するナットを有するボールネジ機構と、一端がナットに連結され、他端が荷受部材に連結された引き上げリンク部材とを備えている。【選択図】図１
