PURPOSE:To make it possible to dispense with a lubricating oil sending device by directly connecting a viscosity pump to a rotary shaft, and supplying oil to a rolling bearing according to the rotation of the rotary shaft. CONSTITUTION:A viscosity pump rotary part 10 facing to a viscosity pump fixing part 9 is fixed to the end of a rotary shaft 3. A viscosity pump, composed of the viscosity pump fixing part 9 and the viscosity pump rotary part 10, is soaked in lubrication oil O stored in an oil bath whose lower half part is formed by a bearing bracket 1 and a bearing cover 7, and driven by the rotational power of the rotary shaft 3. With the rotation of the viscosity pump rotary part 10, the lubricating oil O is, therefore, sent out by means of a pumping action and supplied to a rolling bearing 2 by flowing in the direction of an arrow, thereby a lubricating oil sending device is more required.
