Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent cutting water in spraying form from moving from a lower surface to an upper surface of a bellow cover.SOLUTION: A bellows cover 41 comprises an upper surface (41a) and a lower surface (41b) formed of uneven surfaces, and both side parts supported by support rails (44, 45), and performs telescopic motion. The unevenness (42) of the bellows cover can resist movement of cutting water (Wa), and retain water by forming a gap (46) on the lower surface of the bellows cover in a contracted state. This configuration can prevent the cutting water in spray form from moving from the lower surface to the upper surface of the bellows cover.SELECTED DRAWING: Figure 4 【課題】噴霧状となった切削水が蛇腹カバーの下面から上面に移動することを防止すること。【解決手段】両側部が支持レール（４４、４５）で支持され伸縮させる蛇腹カバー（４１）の、上面（４１ａ）と下面（４１ｂ）とを凸凹面で形成する。蛇腹カバーの凸凹（４２）によって、切削水（Ｗａ）の移動に抵抗を付与することができ、縮んだ状態の蛇腹カバーの下面に隙間（４６）を形成して水を溜めることができる。これにより噴霧状となった切削水が蛇腹カバーの下面から上面に移動することを防止できる。【選択図】図４
