Zusammenfassung:	PURPOSE:To make it possible to confirm whether each tool attached to the spindle of a machine is right or wrong, by providing the plural tools with confirming portions different from each other in the angle to a forque-transmitting keyway. CONSTITUTION:The holding parts Ta of tools T, which are attached to a spindle 11, are provided with confirming portions 21 different from each other in the angle to a keyway 20. Each tool T is attaced to the spindle 11 when a dog 16 for the spindle is in such a fiducial position as to be opposed to a fiducial position detector 17. After that, the spindle 11 is turned by a prescribed angle. An engaging rod 25 is then protruded to find out whether the engaging tip 25a of the rod is engaged in the confirming portion 21 or not, to confirm whether the attached tool T is wright or wrong.
