押圧部１９を設けた工具取付構造。 A main body A having a tapered holding hole 5 for holding a mounting rod, a tool holder B having a tapered mounting rod 14 inserted into the holding hole 5, and a tool holder B provided on the side of the main body A. The operating body C is screwed into the mounting hole 6 so as to be freely movable toward the holding hole 5 and has a pressing portion 17 on the front side. 5, a receiving hole 15 is provided at a position corresponding to the position where the pressing portion 17 of the operating tool C appears and retracts, and a receiving hole 15 is provided to receive the advancing portion of the pressing portion 17 of the operating tool C.
In the tool mounting structure, the side wall of the receiving hole 15 on the distal end side of the mounting rod is an engaging portion 15a that receives a pressing force toward the deeper part of the holding hole 5 by contact with the pressing portion 17. The tool holder B is provided with a pressed portion 21a that is located on the backward locus of the operating body C when the mounting rod 14 is inserted into the holding hole 5. , due to the retreat of the operating body C, the pressed portion 2
1a is provided with another pressing portion 19 that applies a pressing force in a direction to pull out the mounting rod 14 from the holding hole 5.
