PROBLEM TO BE SOLVED: To provide a bearing device which maintains reliability of a bearing, supplies a conventional oil supply amount without increasing an oil supply pressure, and enables adjustment of the oil amount.SOLUTION: A bearing device of the invention rotationally supports a rotary shaft with a lubrication oil disposed on a slide surface of a bearing part to achieve the above object. The bearing device includes an oil supply groove which is located adjacent to the upstream side and/or a downstream side of an oil supply hole, which is formed at a rotation direction front end part of the bearing part, when viewed in a rotation direction or penetrates through the bearing part in an axial direction so as to cover the oil supply hole.SELECTED DRAWING: Figure 2 |
