Zusammenfassung:To provide a tip cover and a machine tool capable of further simplifying a structure of a lifting cover which is lifted up/down following a cross rail.SOLUTION: There is provided a machine tool 1 comprising: a mounting table 3 on which workpiece is mounted; a cross rail 5 capable of being lifted up/down above the mounting table 3; and a main shaft head 7 supported to the cross rail 5. The tip cover 10 comprises: an opening/closing cover 13 which crosses the cross rail 5 and is movable in a horizontal opening/closing direction; a notch 131 which is formed at a cross part of the opening/closing cover 13 with the cross rail 5; a lifting cover 14 which is lifted up/down along the notch 131 and can close the notch; and a coupling mechanism 140 for lifting up/down, the lifting cover 14 following the cross rail 5. The coupling mechanism 140 comprises: a cover side coupling member installed at the lifting cover 14; and a cross rail side coupling member (hanger rail 15) at the cross rail 5, in which the cover side coupling member and the cross rail side coupling member are relatively movable in the opening/closing direction freely.SELECTED DRAWING: Figure 2 【課題】クロスレールに追従して昇降する昇降カバーの構造を一層簡素化できるチップカバーおよび工作機械を提供する。【解決手段】工作機械1は、ワークが載置される載物テーブル3と、載物テーブル3の上方で昇降可能なクロスレール5と、クロスレール5に支持された主軸ヘッド7と、を有する。チップカバー10は、クロスレール5と交差しかつ水平な開閉方向に移動可能な開閉カバー13と、開閉カバー13のクロスレール5との交差部分に形成された切欠き131と、切欠き131に沿って昇降可能かつ切欠きを閉塞可能な昇降カバー14と、昇降カバー14をクロスレール5に追従して昇降させる連結機構140と、を有する。連結機構140は、昇降カバー14に設置されたカバー側連結部材と、クロスレール5に設置されたクロスレール側連結部材(ハンガーレール15)と、を有し、カバー側連結部材とクロスレール側連結部材とは開閉方向へ相対移動自在である。【選択図】図2
