PROBLEM TO BE SOLVED: To solve the problem in which a conventional bolt has a pressing part for pressing a component etc., at a top thereof and may damage the component when the component etc., is pressed with the tip of the bolt, and the problem in which the component is a cutting tool such as a shaft, a drum, or a columnar shank and when the bolt is rotated while pressing a columnar part thereof, the columnar part is damaged to hinder the rotation.SOLUTION: A bolt with pressing means comprises: a screw body which is columnar, and has a screw part formed on an outer peripheral body and also has a circularly-sectioned through hole formed on a screwing-in directional side of the screw part concentrically with the axis of the column, a tool mount part where a tool is mounted being formed on the opposite side from the screwing-in directional side of the screw part; and pressing means mounted rotatably in the through hole while prevented from coming out and pressing a component etc. The pressing means is provided with a pressing part which is softer than the component and projects from an end face of the screw part on the screwing-in directional side.SELECTED DRAWING: Figure 1 |
