Zusammenfassung:PROBLEM TO BE SOLVED: To provide a power unit which supplies a working fluid etc. to a working device in a casing without the use of a rotary joint. SOLUTION: This power unit 30 is used for driving an actuator 13 of the working device 1 which is integrally rotated in the state of being inserted into the casing 200. A drive unit 33 for driving the actuator 13, and a line reel 35, around which a line 36 for connecting the drive unit 33 and the actuator 13 together is wound, are installed on a table 31 capable of being placed at the upper end of the casing 200. The line 36 is fed into the casing 200 through a through-hole 31a which is formed in the center of the table 31, so as to be connected to the actuator 13. COPYRIGHT: (C)2006,JPO&NCIPI
