る。Further, the convex portions 3 are provided at several places in the middle of the strip plate 1, that is, at positions where the strip plate 1 is equally divided into 2 to 8. The convex portion 3 is formed by bulging on the outer peripheral side of the band plate 1 curved in an arc shape, and its inner peripheral side is opened to impart elasticity, so that the convex portion 3 is formed on the inner peripheral surface of the outer tube b. It is important to form them so that they abut elastically.
