Abstract:
A fluid dynamic pressure bearing includes a conical bearing member having a conical bearing surface forming a first gap between a member constituting the rotor. A second gap connected to one end of the first gap and provided over the entire periphery of the shaft is formed between the conical bearing member and the shaft. A tapered seal portion is formed between the conical bearing member and the rotor. The conical bearing member is provided with a circulation hole that communicates the second gap and the tapered seal portion. The circulation hole communicates to another end of the first gap through a part of the tapered seal portion, so that the circulation hole and the other end of the first gap are spaced apart.

Claim (Index 1):
A fluid dynamic bearing that supports a rotor in a rotatable manner with respect to a shaft, comprising:\n a conical bearing member in which at least a part of an inner peripheral surface of the conical bearing member is fixed to an outer peripheral surface of the shaft, the conical bearing member having an outer peripheral surface including at least a conical surface and a conical bearing surface; a first gap provided between the conical bearing surface and the rotor; a second gap provided between the conical bearing member and the shaft over an entire periphery in the circumferential direction, one end of the second gap being connected to one end of the first gap; a space forming a tapered seal provided between the conical surface and the rotor; and a circulation hole formed in the conical bearing member, one end of the circulation hole opening to another end of the second gap, another end of the circulation hole opening to the space forming the tapered seal, and the circulation hole communicating the second gap and the space forming the tapered seal, wherein an opening on the other end of the circulation hole communicates to another end of the first gap through a part of the space forming the tapered seal, so that the opening on the other end of the circulation hole and the other end of the first gap are spaced apart from each other in the part of the space forming the tapered seal.
