PROBLEM TO BE SOLVED: To favorably hold a tool unit in a tool pot. SOLUTION: The tool pot 30 includes a pull stud storage hole 43 sectioned by a ball-stop ring 42 at its base end, and a pull stud 25 of a tool unit 20 is accommodated in the pull stud storage hole 43 while the tool unit 20 is mounted. In addition, the ball-stop ring 42 is equipped with a rigid ball 46 urged by a spring 47 to protrude into the pull stud storage hole 43, and the tool unit 20 is engaged by the rigid ball 46. In such a structure, the tool pot 30 has a through-hole 67 formed to extend from an outer peripheral surface of the pot toward the pull stud storage hole 43 and to pass through from the inside and to the outside. A rod 72 is inserted into the through-hole 67 from a stopper 71 mounted to a conveyance arm 17 for conveying the tool pot 30, and the tool unit 20 is engaged by the rod 72.
