Abstract:
1. A method of manufacturing a cylindrical vibration-damping device comprising: providing a rubber bushing including an inner sleeve, a resin outer sleeve disposed about the inner sleeve, and a rubber elastic body interposed between and bonded by vulcanization to an outer circumferential surface of the inner sleeve and an inner circumferential surface of the resin outer sleeve for elastically connecting the inner and outer sleeves; providing a metallic mounting member having a cylindrical bore such that at least one engaging stepped face is formed on an inner surface of the mounting member at a boundary between a recessed portion and a non-recessed portion thereof; wherein the resin outer sleeve has a smooth outer circumferential surface and arranging the smooth outer circumferential surface to be at least at a location such that an outside diameter of the resin outer sleeve is engaged with the engaging stepped face of the mounting member, and the smooth outer surface at the location to be engaged with the engaging stepped face has the outside diameter which is larger than an inside diameter of the non-recessed portion and approximately equal to an inside diameter of the recessed portion, and press-fitting with the rubber bushing into the bore of the mounting member so that one portion of the outer sleeve situated facing the non-recessed portion of the mounting member is compressed in diameter, while another portion of the outer sleeve situated facing the recessed portion of the mounting member expands in diameter by means of elastic recovery force in order to enter the recessed portion, whereby the smooth outer circumferential surface of the resin outer sleeve deforms to produce an engaged stepped face thereon, which is brought into engagement with the engaging stepped face on the mounting member in an axial direction so as to exhibit a resistance to dislodging of the rubber bushing from the mounting member.
