Claims

[Claims for Utility Model Registration] A main shaft of a machine tool having a mounting hole formed from the tip in the axial direction, an arbor having a base inserted into the mounting hole of the main shaft and a distal end on which a tool is attached; a tapered cylindrical body interposed between the outer circumferential surface of the base of the arbor and the inner circumferential surface of the attachment hole of the main shaft; an elastic member that urges the cylindrical body in the direction of tighter taper fitting; In the arbor mounting device for a machine tool, which is equipped with a tension bolt that is pulled toward the back of the mounting hole, the cylindrical body is provided over the entire length of the base of the arbor, and a slot is formed at the longitudinally intermediate portion of the cylindrical body. An arbor mounting device for a machine tool, wherein the inner and outer circumferential surfaces of the cylindrical body are in contact with the outer circumferential surface of the base and the inner circumferential surface of the mounting hole at both ends of the cylindrical body.
