Document Type and Number:
WIPO Patent Application WO/2022/024519
Kind Code:
A1
Abstract:
A connecting pin 20 is inserted through insertion holes of both an end plate 104 of one segment 1a and an end plate 105 of the other segment 1b such that a head portion 20a of the connecting pin 20 is brought into abutment with the end plate 104 and an inclined surface S3 of each notch portion 20c, 20d projects from the end plate 105. A clamp member 30 is arranged at a position where an inclined surface T2' of a leg portion 30b thereof faces the inclined surface S3 of the notch portion, and the leg portion of the clamp member is press-fitted into the notch portion so as to bring the inclined surface of the leg portion and the inclined surface of the notch portion into surface contact with each other. Due to the movement of the clamp member toward the segment end plate direction, the movement being caused by the press-fitting of the leg portion of the clamp member and corresponding to the inclination angle of the leg portion, the end plates of the two segments are fastened to couple the two segments to each other in the circumferential direction.
