The invention discloses a foldable wheel and belongs to the technical field of wheels. The foldable wheel comprises an evenly-segmented rim, seven folding rods and a center shaft capable of being folded and unfolded. The rim is evenly divided into six segments which are sequentially connected end to end, one ends of the folding rods are connected with the joints of the rim respectively, and the other ends of the folding rods are arranged on the center shaft capable of being folded and unfolded. Each segment of the rim comprises a first steel ring, a second steel ring and a tire. Each folding rod comprises seven folding rod pieces. According to the folding wheel, by the arrangement of the folding rods which can extend and contract and main shafts, further folding and contraction of the wheel are achieved, and more space is saved; besides, the wheel is compact in structure, easy to popularize and use in life, environmentally friendly, light in weight, practical, convenient to use, good in economic benefit and social benefit, and high in practicality.
