<p>PROBLEM TO BE SOLVED: To provide a lubrication device which improves oil collection efficiency by quickening a return of lubrication oil scattering from a rotation object to an oil pan, and can reduce a volume of the lubrication oil.SOLUTION: A lubrication device 10 comprises: a cylindrical oil sump 12 which is arranged so as to cover the outside of a rotation object 3; a bearing 13 which is attached into a case 5 for accommodating the rotation object 3, and rotatably supports the oil sump 12 around its cylindrical center axis; an oil pan 11 arranged at an internal bottom of the case 5; and a gutter 14 which is arranged at an internal face side of the oil sump 12, scrapes oil O which adheres to an internal face of the oil sump 12, and guides the oil to the oil pan 11. The oil sump 12 is arranged in a state that the cylindrical center axis is parallel with a rotating shaft 2 of the rotation object 3, or has a prescribed angle, and arranged in a position in which the oil O scattering from the rotation object 3 adheres to the cylindrical internal face.</p> |
