The invention provides a lifting device and an unmanned transport vehicle provided with the same. The lifting device achieves miniaturization in the lifting direction of the device and improvement of endurance relative to radial external force. A lifting pin (26) is slidably supported by guide rods (Grd1, Grd2) fixed to a lower frame (24). The outer sleeve (28) is disposed radially outward of the lift pin (26) in a state where the cam rollers (CR, CR) of the lift pin are engaged with the spiral grooves (Hg1, Hg2). The outer sleeve (28) is rotatably supported by the upper frame (22) and the lower frame (24). In addition, the outer sleeve is rotated by an actuator (ACTR). The lifting pin and the outer sleeve form a nesting piece, so that miniaturization in the lifting direction is achieved. In addition, since the guide rod receives the radial external force acting on the lifting pin, the condition that the radial external force acts on the cam roller and the spiral groove can be restrained.

    本发明提供升降装置及具备该升降装置的无人输送车。该升降装置谋求装置的升降方向的小型化和相对于径向外力而言的耐力提高的兼顾。将升降销(26)以能够滑动的方式支承于固定于下部框架(24)的引导杆(Grd1、Grd2)。在升降销的凸轮辊(CR、CR)卡合于螺旋槽(Hg1、Hg2)的状态下,将外套筒(28)配置于升降销(26)的径向外方。利用上部框架(22)和下部框架(24)将外套筒(28)支承为能够旋转。另外,利用致动器(ACTR)使外套筒旋转。由于升降销和外套筒成为嵌套件,因此谋求了升降方向的小型化。此外,由于引导杆承受作用于升降销的径向外力,因此能够抑制该径向外力作用于凸轮辊和螺旋槽的状况。
