In the flange of the structural null plate-like of the suffering pressing in component

摘要

PROBLEM TO BE SOLVED: To provide a press-fitted member 1 having a hole for a press fit capable of enhancing pressed strength and rigidity of a bearing boss, which is provided to project from a flange portion to one side, without using a reinforced collar.;SOLUTION: A first cylindrical portion 1C is formed to project from a flat- plate like flange portion 1A to one side A. Then, a second cylindrical portion 1E is formed so that A side end portion 1D of the first cylindrical portion 1C is turned inward and is also folded toward another side B along an inner face 1E of the first cylindrical portion 1C. A hole 1G for a press fit along the axial direction A-B of the cylindrical portion is formed inward the second cylindrical portion 1F, and the bearing boss 2 is also formed by means of the first cylindrical portion 1C and the second cylindrical portion 1F having the hole 1G for a press fit. A press-fitting member 10 is press-fitted and fixed to the hole 1G for a press fit of the second cylindrical portion 1F.;COPYRIGHT: (C)2002,JPO
