Description
図1は、本発明の参考例1に係るボール1を示すものである。このボール1は、球技用のものであり、図2に示すように、芯部としてのチューブ2と、該チューブ2の外周面を覆う表皮を構成する複数の表皮パネル3、3、…とを備えている。この参考例1では、表皮パネル3の枚数を12枚としており、従って、各表皮パネル3の面積は、ボール1の総表面積の8%以上となっている。また、ボール1の直径は、16cm以上25cm以下に設定されている。尚、表皮パネル3の数や、ボール1の直径は上記に限られるものではない。
図25は、本発明の参考例2に係るボール1の断面図である。この参考例2に係るボール1は、チューブ2の補強層5に設けた発泡材57が参考例1のように分割されていない点で参考例1のものと異なっている。以下、参考例2のボール1について、参考例1と同じ部分には同じ符号を付して説明を省略し、異なる部分を詳細に説明する。
