A sliotar or sliothar ((:ʃlʲɪt̪ˠəɾˠ)) is a hard solid sphere slightly larger than a tennis ball, consisting of a cork core covered by two pieces of leather stitched together. Sometimes called a "dust" or "hurling ball", it resembles a baseball with more pronounced stitching. It is used in the Gaelic games of hurling, camogie, and rounders. ==Dimensions== An official Gaelic Athletic Association (GAA) sliotar, as used in top level hurling competitions such as the National Hurling League or the All-Ireland Senior Hurling Championships is subject to strict regulations as regards its size, mass and composition. The following regulations apply: * The diameter is between 69 mm and 72 mm (not including the rib) * The mass is between 110 g and 120 g * The rib height is between 2 mm and 2.8 mm, and width between 3.6 mm and 5.4 mm * The leather cover can be between 1.8 mm and 2.7 mm and is laminated with a coating of no more than 0.15 mm Approved sliotars carry a GAA mark of approval. The GAA maintains a list of approved suppliers, based on manufacturers who pass their inspection.〔(【引用サイトリンク】title=GAA Approved Suppliers )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sliotar」の詳細全文を読む スポンサード リンク
