Cylindrical vibration-isolating device

摘要

A cylindrical vibration-isolating device including: an elastic body interposed between an inner and an outer metal sleeves disposed coaxial relationship with each other, such that at least one axial end portion of the inner sleeve is located axially outward of the elastic body, a connecting rubber layer integrally formed with and protruding axially outwardly from the elastic body and secured to an outer circumferential surface of the end portion of the inner sleeve; and an annular sealing-rubber member formed integrally with and protruding axially outwardly from the connecting rubber layer to protrude axially outwardly from an end face of the inner metal sleeve, which has a radially inner base portion rising with a concave surface from a first axial position on the outer circumferential surface of the end portion, which is axially inwardly spaced apart from the end face of the inner sleeve.
