Zusammenfassung:PROBLEM TO BE SOLVED: To provide a rubber bush with a pin in which a shaft part, a rubber part, and an outer cylinder part can be integrated without vulcanization adhesion, and when the rubber part has reached the end of the service life, only the rubber part can be easily replaced while reusing the shaft part and the outer cylinder part, and provide an assembling/disassembling method of the same.SOLUTION: A rubber bush 10 with a pin comprises: a shaft part 1; an outer cylinder part 2 disposed on the outer peripheral side of the shaft part and mounted to a through hole 41 of an attachment object 4; and a substantially cylindrical rubber part 3 fitted and pre-compressed between the shaft part and the outer cylinder part. The outer cylinder part comprises a plurality of outer cylinder divided pieces 21, 22, 23 divided in a circumferential direction. Shelf parts 211, 221, 231 for receiving load which pre-compresses the rubber part in a shaft core direction are formed respectively in axial end parts of the outer cylinder divided pieces on the inner diameter side than outer peripheral surfaces 212, 222, 232 of the outer cylinder divided pieces.SELECTED DRAWING: Figure 1 【課題】軸部とゴム部と外筒部とを加硫接着することなく一体化し、ゴム部が寿命に達したときには、ゴム部のみを簡単に交換して軸部と外筒部とを再利用できるピン付きゴムブッシュ及びその組立て分解方法を提供する。【解決手段】軸部1と、軸部の外周側に配置され取付対象物4の貫通孔41に装着される外筒部2と、軸部と外筒部との間に嵌合され予圧縮された略筒状のゴム部3とを備えたピン付きゴムブッシュ10である。外筒部は、周方向で分割した複数個の外筒分割片21、22、23からなり、それぞれの外筒分割片の軸方向端部には、ゴム部を軸心方向へ予圧縮する荷重を受け止める棚部211、221、231が、当該外筒分割片の外周面212、222、232より内径側に形成されている。【選択図】 図1
