PROBLEM TO BE SOLVED: To provide a tool mounting device with a fluid feeding passage for an angle head in which a configuration is simplified and fluid such as a cutting fluid can be supplied to a tool continually and satisfactorily.SOLUTION: A tool mounting device includes: a tool-mounting rotary shaft having a hollow part for a fluid passage formed from one end side of a shaft body to the other end side direction, and mounting a tool at one end side of the shaft body in communication with the hollow part; rotary shaft mounting means for detachably mounting this rotary shaft to an angle head and rotating the rotary shaft; a tubular part for cover where the rotary shaft is rotatably fitted in the shaft body and provided by regulating the movement to an axial direction and forming a cylindrical gap part between an outer circumferential wall surface of the shaft body and itself; a fluid inlet provided in the tubular part in communication with the gap part; a fluid introduction hole provided in the shaft body by bringing the hollow part into communication with the gap part; and seal means for sealing both ends of the gap part. The other end side of the hollow part is constituted so as to be closed.SELECTED DRAWING: Figure 2 【課題】構成を簡素化し、切削液等の流体を工具へ連続的かつ、良好に供給できるアングルヘッド用流体供給通路を備えた工具取付装置を提供する。【解決手段】軸本体の一端側から他端側方向へ形成した流体通路用の中空部を有し、軸本体の一端側に中空部と連通させて工具を取付ける工具取付用回転軸と、この回転軸をアングルヘッドに着脱可能に取付けて前記回転軸を回転する回転軸取付手段と、回転軸を回転自在、かつ、軸方向への動きを規制すると共に軸本体の外周壁面との間に円筒状の間隙部を形成して軸本体に嵌合して設けたカバー用筒状部と、前記間隙部と連通させて前記筒状部に設けた流体入口部と、間隙部と中空部を連通させて軸本体に設けた流体導入孔と、間隙部の両端部をシールするシール手段とを備え、中空部の他端側は閉塞するように構成する。【選択図】図２
