PROBLEM TO BE SOLVED: To provide a simple and inexpensive clamp device for milling in which a plurality of kinds of functions are integrated with each other. SOLUTION: Each split piece 49 of a collet 45 is externally pressed and deformed to be pressed against an inner circumference of each hole while a tapered part 59 at a tip of a draw bar 57 is pressed against an inclined part 51 of each split piece 49 as the draw bar 57 is lowered by the contraction of a piston.
