摘要：In a tool holder, a tip run-out correction mechanism includes an annular

stepped portion (41) formed on a cylindrical support portion (48) of a holder body (31); aring member (42) rotatably fitted onto the annular stepped portion (41); an eccentriccam (43) disposed within the ring member (42), the eccentric cam (43) extending radiallythrough the ring member (42) and being rotatable about a radially extending axis; and apin (44) disposed within the ring member (42) to be movable along a direction parallel tothe centre axis of a flange portion (33) of the holder body (31). One end of the pin (44) isin contact with the eccentric cam (43), and the other end of the pin (44) is in contact with arear end face of a clamp sleeve (38) which clamps a tool (29) inserted into a chuck sleeve(34) of the holder body (31). The eccentric cam (43) is rotated so as to adjust a pressingforce that the pin (44) applies to the rear end face of the clamp sleeve (38), thereby toelastically deform a base end portion (341) of the chuck sleeve (34) in a radial direction insuch a manner that tip run-out of the tool approaches zero.
