PURPOSE:To provide a cubic resin molded piece having excellent mechanical property such as compressive force and resilience. CONSTITUTION:By using a cloth with cubic structure having top and bottom base cloths 1 and 2 connected by connecting threads 3, a molded piece is impregnated with resin so as to make gap between the top and bottom base cloths 1 and 2. In the resin molded piece, resin sticking quantity of the connecting thread 3 is 10% or more of sticking quantity of the whole resin. Thus, mechanical strength such as compressive strength and resilience is improved and rate of compression residual skew can be reduced. |
