CYLINDRICAL VIBRATION-DAMPING DEVICE AND METHOD OF PRODUCING THE SAME, AND VIBRATION-DAMPING STRUCTURE INCLUDING THE CYLINDRICAL VIBRATION-DAMPING DEVICE

摘要

Disclosed is a method of producing an impact-type cylindrical vibration-damping device comprising the steps of: preparing a main rubber elastic body of hollow cylindrical shape including a mass installation groove open in an outer circumferential surface thereof and a slit extending over an entire axial length thereof; expanding the elastic body at the slit in order to mount the elastic body about a rod shaped vibrating member through the slit from a radially outer side such that the elastic body has an abutting inner surface adapted to come into abutting contact against the vibrating member at a portion where a radial distance between an inner circumferential surface of the elastic body and an outer circumferential surface of the vibrating member is smallest; preparing a mass member separately from the elastic body; and fixing the mass member to the elastic body by fitting the mass member onto the mass installation groove.
