Abstract
Multiple ring-shape cylindrical members (3) and four wires (4) that link these cylindrical members (3) in a tubular shape are provided. Each cylindrical member (3) comprises two first protruding parts (33) which protrude from the top end face (31) and are formed at both ends of a first diameter (D1), two second protruded parts (34) which protrude from the bottom end face (32) and are formed at both ends of a second diameter (D2), two first small cylindrical members (35) for wire insertion mounted on the outer circumferential face of the cylindrical member respectively at the vicinity of each protruded part (33), and two second small cylindrical members (36) mounted on the outer circumferential face of the cylindrical member respectively at the vicinity of each second protruded part (35), and the first diameter (D1) and the second diameter (D2) are approximately perpendicular.
