PROBLEM TO BE SOLVED: To provide a dynamic pressure bearing device for improving abrasion resistance of a thrust bearing part. SOLUTION: A flange part 2b of a shaft member 2 is formed of resin, and pressure is generated by the dynamic pressure action of fluid in thrust bearing clearance between its end surface 2b1 and a housing inner bottom surface 7c1, and the shaft member 2 is supported in a noncontact state in the thrust direction by this pressure. An inclined face 24 approaching the inner bottom surface 7c1 toward the outer diameter side, is formed in a part facing the thrust bearing clearance C of the end surface 2b1 of the flange part 2b.
