Abstract
A cylindrical vibration-damping device includes: a rubber bushing having a rubber elastic body elastically connecting an inner sleeve and a resin outer sleeve; a rigid mounting member having a cylindrical bore into which the rubber bushing is press fit; an engaging stepped face formed on an inner surface of the mounting member; and an engaged stepped face produced on an outer surface of the outer sleeve once the outer sleeve is press fit into the cylindrical bore of the mounting member, by means of elastic deformation of the outer sleeve. The engaged stepped face is opposed to the engaging stepped face in an axial direction of the device, and is brought into engagement with the engaging stepped face so as to exhibit a resistance to dislodging of the rubber bushing from the mounting member in at least one of opposite axial directions. The method of producing the same is also disclosed.
