ならず、切削加工が複雑となっていた。In such a conventional linear electric drive device, due to a change in the diameter of the actuating rod 9 or a change in the shape of the nut 8, the actuating rod cannot fit into the hollow part of the hollow rotating shaft, or the flange of the nut does not fit into the hollow part of the hollow rotating shaft. Sometimes it would not attach to the end of the shaft. Furthermore, if the shaft end of the hollow rotary shaft is not perpendicular, the axial center line of the hollow rotary shaft and the shaft center line of the nut will not match, and the shaft end of the operating shaft will be on the inner periphery of the hollow rotary shaft, making it impossible to operate. For this reason, it is necessary to attach an electric linear drive device to the machine tool and perform machining while rotating the end face of the hollow rotary shaft 5, making the cutting process complicated.
