Abstract:
Provided is an overhead transport vehicle 1 wherein a vertically movable device 10 is provided with: cushioning mechanisms (second cushioning mechanism 40 and first cushioning mechanism 50) respectively having a plurality of belts 9 mounted thereto; and a base 10A provided with a holding device 11. The cushioning mechanisms have support sections (fourth body member 46 and first body member 54) arranged below the base. The base is mounted through vibration isolation sections (second spring member 48 and first spring member 58) so as to be vertically movable relative to the support sections. The plurality of cushioning mechanisms are connected by a link mechanism 70, and the link mechanism operates so as to reduce the distance between the base and the support sections of the cushioning mechanisms which are connected to each other.
