The present invention relates to a non-pneumatic wheel mainly used for forklifts and industrial, agricultural, mining, and construction vehicles, wherein the tread portion that contacts the ground during rotation or traveling does not detach from the outer wheel, and impacts and vibrations resulting from irregularity of the ground are minimized, thereby improving the ride quality. The non-pneumatic wheel according to the present invention comprises: a cylindrical inner wheel having flange portions formed on both edges thereof so as to face each other, each flange portion having pin fastening holes formed at a constant interval along the circumferential surface thereof; a cylindrical outer wheel having a tread portion integrated with a drum and molded on a drum outer surface having a through-hole or a corrugation formed thereon such that the inner peripheral surface of the tread portion is embedded in the through-hole or the corrugation, thereby containing the inner wheel; a cylindrical middle wheel installed between the inner wheel and the outer wheel, the middle wheel having hollow quadrangular elastic bodies arranged to maintain a predetermined interval, each arranged elastic body having a peripheral edge portion formed on the inner peripheral surface thereof, the peripheral edge portion having a pin fastening cavity formed therein, and a rib being formed at the center portion thereof; a holding means for tightly coupling the inside of the outer wheel to the outside of the middle wheel and then holding the middle wheel and the outer wheel such that the same can be coupled/disassembled; and coupling pins configured such that, after the inside of the middle wheel is tightly coupled to the outside of the inner wheel, the coupling pins are press-fitted and coupled through the pin fastening holes of the inner wheel and the pin fastening cavities of the middle wheel, thereby coupling the inner wheel and the middle wheel such that the same can be coupled/disassembled.
