ELASTIC BUSH AND METHOD OF PRESS-FITTING ELASTIC BUSH

摘要

An outer tube-less type elastic bush (2) allowing an elastic body (21) fixed to the outer periphery of an inner tube (20) to be brought into direct contact with the inner surface of a supporting hole (1a) in a supported body (1) and having insert sleeves (22) buried in the elastic body (21), wherein flange parts (22a, 22b) bent in radial outside direction are formed at both ends of an insert sleeve (22) so as to be extended in radial outside direction from the axial projection plane of the supporting hole (1a) in the state of the elastic bush being fitted into the supporting hole (1a), and axial cut-out (22c) and a split groove (21e) are formed in the insert sleeve (22) and the elastic body (21), respectively, so that the flange part (22a) at one end can be reduced in diameter and the elastic bush (2) can be inserted from the flange part (22a) side into the supporting hole (1a), whereby a resistance force against withdrawal of the supported body from the supporting hole (1a) is increased and the initial compressibility of the elastic body (21) is increased so as to increase a performance.
