接せしめたことを特徴とする筒状防振ブツシユ。 A cylindrical anti-vibration bushing in which a vibration-isolating rubber body is disposed between an outer cylinder and an inner cylinder, and the outer cylinder is press-fitted and fixed into a cylindrical holding member, and the inner cylinder has a vibration-isolating rubber body in an axially central portion. A bulging portion having a spherical surface and bulging outward in the radial direction is formed, while the vibration isolating rubber body is divided into two at the center in the axial direction and the outer circumferential surface is joined to the outer cylinder,
In the axially inner end of each vibration isolating rubber body, an insert made of a resin material with good sliding properties and having a concave surface is embedded and fixed so as to protrude axially inward by a predetermined amount. The outer cylinder of the rubber body is press-fitted into the cylinder through the openings at both ends of the holding member, and each of the concave surfaces is slidably brought into close contact with the outer periphery of the bulge by the elastic force of the vibration isolating rubber body, and each of the above-mentioned prevention A cylindrical anti-vibration bushing characterized in that the outer end of the vibrating rubber body has a sealing rubber part extending toward the outer periphery of the end of the inner cylinder, and the tip thereof is in liquid-tight contact with the outer periphery. .
