PROBLEM TO BE SOLVED: To provide a slide bearing which can elongate a life by improving the durability of an elastic body.SOLUTION: A rack bush 1 comprises: a cylindrical bush main body 2 which is accommodated in a cylindrical housing, and supports a load applied to a rack shaft while permitting the movement of the rack shaft 5 to an axis O-direction, and into which the rack shaft is inserted; and an elastic member 3 which is attached to the bush main body 2, protrudes outwardly from an external peripheral face of the bush main body 2, abuts on an internal peripheral face of the housing when the rack bush is accommodated in the housing, and energizes the bush main body 2 to the inside of a radial direction. The bush main body 2 has a slit which is formed along the axis O-direction toward the other end face from one end face. The elastic member 3 has a protrusion which protrudes outwardly while being inclined to the radial direction of the bush main body 2, and abuts on the internal peripheral face of the housing.SELECTED DRAWING: Figure 2
【課題】弾性体の耐久性を向上させて長寿命化を図ることができる滑り軸受を提供する。【解決手段】ラックブッシュ1は、円筒状のハウジング内に収容され、ラック軸5の軸O方向の移動を許容しつつ、ラック軸に加わる荷重を支持するものであり、ラック軸が挿入される筒状のブッシュ本体2と、ブッシュ本体2に装着され、ブッシュ本体2の外周面から外方に突出し、ラックブッシュをハウジング内に収容した場合にハウジングの内周面と当接して、ブッシュ本体2を径方向内方に付勢する弾性部材3と、を備えている。ブッシュ本体2は、一方の端面から他方の端面に向けて軸O方向に沿って形成されたスリットを有する。弾性部材3は、ブッシュ本体2の径方向に対して傾斜しながら外方に突出して、ハウジングの内周面と当接する突出部を有する。【選択図】図2
