Method for mounting an elastic annular member

U.S. Patent Number: 5392505

Abstract: A method of fitting an elastic ring on an outer circumferential portion of a workpiece includes the steps of inserting a hollow diameter-enlarging member into the elastic ring to hold the elastic ring on an outer circumferential portion of the diameter-enlarging member, in an enlarged diameter state; holding, at a holding position, the diameter-enlarging member having the elastic ring held thereon; and inserting the workpiece, which has a flange portion, into the diameter-enlarging member such that the flange portion of the workpiece contacts an end surface of the diameter-enlarging member and displaces the diameter-enlarging member from the holding position while keeping the elastic ring at the holding position to transfer the elastic ring to the workpiece by a contraction of the elastic ring from the enlarged diameter state to a reduced diameter state.
