Abstract

PURPOSE: To simplify the manufacturing and to improve the productivity of the sleeve by cylindrically bending the leaf on which the convex screw heads are formed by the press processing, with the convexed side outside.
CONSTITUTION: Three rows, for example, of multi number of the convexes 2 as the screw heads are formed on metal leaf 1 by the press processing. In this case, the convexes 2 of each row are arranged uniformly spaced and inclined at the same angle, and each row is shifted downward from left to right. Then, the leaf 1 with press-processed convex parts 2 is cylindrically bent by the rolling process, etc. with the convex parts 2 outside, and both ends of the leaf 1 are overlapped 3 and fused by, for example, spot welding to form a cylinder 4. The sleeve 6 is completed by providing the flange on one end of the cylinder 4 by press fitting.
