PURPOSE:To facilitate manufacture and repair work and perform cost down for a main unit formed by connecting many earth links and coupling rings to net shape, by constituting the above described main unit from divided small net elements having different shapes and dimensions. CONSTITUTION:A tire protector main unit is constituted by connecting many earth links 1 mutually with coupling rings 2. In this case, the above described main unit is manufactured by previously forming small net elements to shape of at least four kinds, triangular element 3, square element 4, rectangular elements 5-7, and pentagonal element 8, respectively in several sets. Here each small net element is formed to such dimensions that if assumed 1.0 for a side of the square element 4, length is as shown in the drawing as the ratio for the square element. In this way, each small net element is suitably combined and arranged so as to meet desired shape and dimensions of a tire, then the coupling rings 2 of the neighboring sets are mutually connected by a suitable connecting ring to complete the desired protector. |
