A dynamic pressure bearing motor includes a rotary shaft, a rotary hub coupled to the rotary shaft, a dynamic pressure bearing sleeve that supports the rotary shaft by dynamic pressure and has a fallout stopper flange section that protrudes outward in the radial direction, a thrust dynamic pressure bearing section formed in an axial direction between the dynamic pressure bearing sleeve and the rotary hub, and a circular ring-shaped member that surrounds an outer circumference surface of the dynamic pressure bearing sleeve. The circular ring-shaped member has a hub mounting section that connects to an end surface of the rotary hub in a region radially outside the thrust dynamic pressure bearing section, and a main body section that protrudes inward from the hub mounting section. An inner circumference surface of the hub mounting section of the circular ring-shaped member opposes in the radial direction an outer circumference surface of the fallout stopper flange section of the dynamic pressure bearing sleeve, and the main body section of the circular ring-shaped member opposes in the axial direction the fallout stopper flange section of the dynamic pressure bearing sleeve to prevent the dynamic pressure bearing sleeve from falling out in the axial direction.
