The bearing unit includes a surrounding portion arranged to surround the shaft, and a facing portion arranged to face an end of the shaft. A gap between the shaft and the surrounding portion includes two dynamic pressure generation portions and an intermediate portion arranged between the two dynamic pressure generation portions. The bearing unit further includes a path of a lubricant arranged to connect one side of one dynamic pressure generation portion and the intermediate portion.
