PROBLEM TO BE SOLVED: To provide an endless type three-dimensional storage, making all of parts small to be easily replaced without lowering the strength, preventing breakage of a chain, preventing a worker from being crushed to death, and easily utilized. SOLUTION: In this three-dimensional storage, each of chains is made double, four lines in total, and a short rotating shaft where two sprockets for two-line chains of one side are passed is supported by two pillow blocks. Thus, a large-sized chain is not used, so that all parts are small, and since two lines are provided per side, breakage of one chain can be found quickly, and further the bottom of a suspending storage can be cut at equal intervals like a comb. Another elevating device with a rotary roller is incorporated and the rotary roller is moved up and down and rotated, whereby a vehicle can be automatically carried in and out by unmanned operation to achieve cost reduction and safety.
