PROBLEM TO BE SOLVED: To provide a connecting device of a screw shaft in a metal injection- forming machine, with which the screw can easily be attached/detached to a driving shaft at a low cost. SOLUTION: The screw shaft 11 of the screw 10 and a driving shaft 27 driven to the rotating direction and the axial direction, are connected with the connecting device 40 and spline shafts 13, 28. The connecting device 40 is constituted with plural pieces of restricting balls 52, 52,... interposed between the screw shaft 11 and the driving shaft 27, a holding sleeve 46 for holding the restricting balls and an air cylinder 65 for driving the holding sleeve 46 in the releasing direction. |
