Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent entrance of cutting water to the internal part of a device in a way that no hole is formed in a bellows cloth even when butts like a sharp-edged tool is dispersed through cutting of a rigid material, in a cutting device having a mechanism to drain cutting water, received by the bellows cloth, through a water case. SOLUTION: The cutting device 10 comprises a chuck table 21 to hold a workpiece; a cutting means 22 to cut the substance to be cut by a rotary blade 31; a feed means 24 for the chuck table 21; bellows cloths 43 and 44 disposed expandably in a cutting direction; and a water case 47 to drain cutting water received by the bellows cloths 43 and 44. The upper part of the bellows cloth is covered by a protection sheet 11 and a protection sheet winding/feeding means 12 is disposed to wind or feed the protection sheet 11 along with expansion and contraction of the bellows cloth.
