複数の弾性スペーサを互いに適宜の間隔を保持し
て介在させ、該弾性スペーサの内、上記弾性板の
中心部に配置した弾性スペーサの比重を最も小さ
くし、この弾性スペーサより外側に配置した弾性
スペーサの比重を漸次大きくしてマツト芯材を構
成し、このマツト芯材の外周に保護カバーを被覆
したことを特徴とする体育マツト。 A plurality of elastic spacers having the same height are interposed between two flat elastic plates while maintaining an appropriate distance from each other, and among the elastic spacers, the specific gravity of the elastic spacer placed at the center of the elastic plate is This athletic mat is characterized in that a pine core material is formed by making the specific gravity of the elastic spacer the smallest and gradually increasing the specific gravity of the elastic spacers arranged outside the elastic spacer, and the outer periphery of the pine core material is covered with a protective cover.
