PROBLEM TO BE SOLVED: To provide a dynamic pressure bearing motor which can easily fill the lubricating oil of a dynamic pressure bearing means and in a short time, by the mass production property into consideration. SOLUTION: This dynamic pressure bearing motor is provided with a fixing member 102, a rotor hub 104, and a dynamic pressure bearing means 106 placed between them. The dynamic pressure bearing means 106 has a shaft member 120, a bearing sleeve body 122, a pair of radial dynamic pressure fluid bearing means 150 and 152, and a pair of thrust dynamic pressure fluid bearing means 158 and 160, a shaft hole 176 is formed to the shaft member 120, a large inner diameter part 19 is provided at one end part of the shaft hole 176, the lubricating fluid of the radial and thrust dynamic pressure fluid bearing means 152, 158, and 160 is poured to the large inner diameter part 190 through the shaft hole 176, and the poured lubricating oil is permeated by the capillary phenomenon, so as to be filled to those dynamic pressure fluid bearing means.
