To realize an article lifting device having high durability.SOLUTION: An article lifting device includes a holding member for holding an article such as a container and a screw shaft in the vertical direction for screwing and supporting the holding member, and raises and lowers the holding member by rotation of the screw shaft. The screw shaft is suspended and supported by an upper bearing part bearing an upper part of the screw shaft. The upper part of the screw shaft is allowed to rotate around an axial center of the screw shaft and born by the upper bearing part, which regulates the movement in an axial center direction of the screw shaft. A lower part of the screw shaft is allowed to rotate around the axial center of the screw shaft and born by a lower bearing part which also allows the movement in the axial center direction of the screw shaft. Specifically, a thrust bearing receiving a load in the vertical direction transmitted from the screw shaft is also included in the upper bearing part.SELECTED DRAWING: Figure 4
【課題】耐久性の高い物品昇降装置を実現すること。【解決手段】容器等の物品を保持する保持部材と、この保持部材を螺合支持する上下方向の螺子軸を備え、この螺子軸の回転によって保持部材を昇降させる構成とした物品昇降装置であって、螺子軸を、この螺子軸の上部を軸受する上側軸受部で吊持支持する。すなわち、螺子軸の上部を、この螺子軸の軸心を中心とする回転を許容し、かつ、この螺子軸の軸心方向への移動を規制する上側軸受部で軸受し、螺子軸の下部を、この螺子軸の軸心を中心とする回転を許容し、かつ、この螺子軸の軸心方向への移動をも許容する下側軸受部で軸受する。具体的には、上側軸受部に、螺子軸から伝わる上下方向の荷重を受けるスラスト軸受を備える。【選択図】図4
