Claims

[Claims for Utility Model Registration] 1. A main body having a connecting portion for a machine tool at one end is provided with an insertion hole for inserting a shank having an opening in the end face of the other end, and the other end of the main body is provided with an insertion hole for inserting a shank, and In a tool holder equipped with a fastener for tightening and fixing the shank inserted into the insertion hole, a receiver for receiving the rear end of the shank is provided in the insertion hole. Additionally, the receiver is composed of, in order from the opening side, a contact plate for abutting the rear end of the shank, an elastic body, and a base material connected to the main body. A tool holder. 2. The main body having a connection part for the machine tool at one end is provided with an insertion hole for inserting a shank having an opening in the end face of the other end, and the other end of the main body is provided with a shank inserted into the insertion hole. In a tool holder equipped with a fastener for tightening and fixing the shank, the insertion hole has a non-circular cross-sectional shape, and a receiver for receiving the rear end of the shank is provided in the insertion hole. The receiver has a non-circular outer shape corresponding to the cross-sectional shape of the insertion hole so that the insertion hole can move freely in the axial direction and is prevented from rotating relative to the main body. , and a tool driver having a fitting groove for fitting a tongue provided at the rear end of the shank on the surface on the side of the opening, and a tool driver arranged deeper in the insertion hole than the tool driver. and a preset screw having a male thread provided on the outer circumferential surface screwed into a female thread formed on the inner circumferential surface of the insertion hole.
