<p><P>PROBLEM TO BE SOLVED: To provide a cylindrical member fastening device and its fastening method for fastening a cylindrical member having a large diameter which is capable of enhancing the workability, stabilizing the fastening torque, and reducing the cost. <P>SOLUTION: The cylindrical member fastening device includes a cylindrical member holder 230 with a first cylindrical member 81 being loaded thereon and fixed thereto, and a ring wrench 200 having a torque wrench engagement unit 220 which engages the other cylindrical member by an engagement unit 214 provided on an end face in the axial direction opposite to the fastening direction with the first cylindrical member 81 formed on the other cylindrical member 137, and has a recess 221 to be engaged with the torque wrench 240. The ring wrench has a cylindrical engagement member 210 having a plurality of axial through-holes 211 to be matched with at least a part of a plurality of axial engagement holes 215 formed in the engagement unit in the circumferential direction, and the torque is transmitted to the other cylindrical member from the ring wrench by inserting a pin 212 in the through-hole matched with the engagement hole. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
