An object of the present invention is to provide a vertical bearing device having a high cooling capacity without causing an increase in size, a complicated structure, and a complicated maintenance. A cooling unit includes a wind inlet 521 located in a preset setting range 100 into which cooling air flows. This setting range 100 is such that the distance from the upper end to the lower end of the oil chamber 45 in the axial direction of the rotating shaft member is h, and the shortest distance between the outer peripheral surface 243 of the casing 24 and the inner peripheral surface of the cover 27 is a. It is set as follows. That is, the setting range 100 is set between 1/4 h upward and 5/4 h downward with the upper end of the oil chamber 45 as the reference position in the axial direction of the rotating shaft member. The setting range 100 is set between the outer peripheral surface 243 and 2a with the outer peripheral surface 243 of the casing 24 as a reference position in the radial direction of the rotating shaft member.
