A device for fixing a tool element to a spindle of a rotary tool includes a first rotary member and a second rotary member adapted to be mounted on the spindle in a confronting relationship with each other in an axial direction of the spindle. The second rotary member has an abutting surface for abutment of the tool element on the side opposite to the first rotary member. A resilient member is interposed between the first rotary member and the second rotary member. A tightening member is operable to press the tool element on the second rotary member with the first rotary member abutted on a part of the spindle. |
