A main shaft coupling structure of a machining center is provided to improve acceleration, deceleration and vibration of the main shaft, and to facilitate assembling because the main shaft and rotary joint can be simply connected. A main shaft coupling structure of a machining center comprises a rotary joint(1) which supplies cutting fluid and air through a tool, a conduit line which attaches and detaches the tool and supplies the cutting fluid and air, a draw bar(2) which is inserted into a spindle shaft(5), an unclamp pusher(3) which is mounted on the end part of the rotary joint, and a shaft(4) which is placed in the unclamp pusher. |
