TRAVELING WHEEL DEVICE FOR MOVING SHELF

摘要

PROBLEM TO BE SOLVED: To prevent a shelf from being meandered and slanted and to make a sound quiet by preventing a wheel slip at the time of moving a movable shelf. SOLUTION: A movement shelf is constituted such that a movable shelf is appropriately moved at the time of receipt and disbursment operation and a work passage 5 having a predetermined width is formed between the shelves. A combined type traveling wheel GWR is formed by providing a rotation shaft 13 extending to an opening direction of a bottom portion of the movable shelf and combiningly providing an elastic rolling wheel 21 having a slightly larger diameter than that of an outer periphery stepping surface of a wheel 17 made of metal coaxially rotating with the rotation shaft 13 and made of an elastic body. At least two wheels GWR are provided on an opening direction of the movable shelf at an interval.
