Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an automatic tool changer stably gripping a tool holder without damaging a change arm and the like, and also without making a loud sound to the surroundings. SOLUTION: The automatic tool changer comprises: a clamp block 21 openably and closably provided on the side of the change arm 3, and gripping the tool holder H with a grip part 3a or releasing the grip; and driving means 9-12, 22-28 interlocked with a cam wheel 4 to open/close the clamp block 21. The driving means 9-12, 22-28 are interlocked with the cam wheel 4 so that the clamp block 21 is opened in the position where the change arm 3 does not grip the tool holder H, and that the clamp block 21 is closed in the position where the change arm 3 grips the tool holder H.
