To provide a sintered bearing integrally including a seal member, which blocks movement of a fluid along a thrust direction of a shaft, with a simple structure at low costs.SOLUTION: A sintered bearing includes: a bearing body in which a through hole is formed at a center part and which is formed by a sintered material and has a substantially cylindrical shape; a discoid seal member which is disposed so that one surface side contacts with the bearing body and in which an opening is formed at a center part; and a block shaped engagement member which contacts with at least the other surface side of the seal member and sandwiches the seal member with the bearing body.SELECTED DRAWING: Figure 1 【課題】シャフトのスラスト方向に沿って流体の移動を阻止するシール部材を一体に備えた焼結軸受を、簡易な構成で低コストに提供する。【解決手段】中心部に貫通孔が形成された、焼結材料から成る略円筒形の軸受本体と、一面側が前記軸受本体に接するように配され、中心部に開口が形成された円板状のシール部材と、前記シール部材の少なくとも他面側に接し、該シール部材を前記軸受本体との間で挟持するブロック状の係止部材と、を備えていることを特徴とする。【選択図】図１
