LUBRICATING STRUCTURE OF ROTOR DEVICE AND MANUFACTURING METHOD OF LUBRICATING STRUCTURE OF ROTOR DEVICE

PROBLEM TO BE SOLVED: To reduce the manufacturing man-hour of the lubricating structure of a rotor device by performing plug working simultaneously with a process of pressing a plug in a hollow hole for introducing lubricating oil in a shaft body to block up an opening of the hollow hole. SOLUTION: In this manufacturing method of a lubricating structure of the rotor device including a support shaft (shaft body) 4 having a hollow hole 4a for introducing lubricating oil to supply lubricating oil to a bearing of the rotor device and an outlet hole 4c for supplying lubricating oil and the plug 20 pressed in the hollow hole 4a to block up the opening on one end side of the support shaft 4, plate-like plug raw material 21 is disposed on the opening side of the end part of the support shaft 4, the disposed plug raw material 21 is pressed in the hollow hole 4a of the support shaft 4 by a punch 22, and throttled like a closed end cylinder in the inner surface of the hollow hole 4a, and the formed plug raw material 21 is pressed intact in the hollow hole 4a to form the plug 20.
