PROBLEM TO BE SOLVED: To provide a dynamic pressure bearing device capable of fixing a thrust member and a shaft member powerfully without reducing rigidity of a bearing. SOLUTION: Chamfers 9e, 9h and a large diameter inner peripheral face 9f are provided at one end of the inner periphery of the thrust member 9, and a space as an adhesive accumulation part is formed between the large diameter inner peripheral face and an outer peripheral face of the shaft member 2. Consequently, since sufficient volume of adhesive can be kept between an inner peripheral face of the thrust member and the outer peripheral face of the shaft member, strength of adhesive bonding can be increased. Since the adhesive overflowing from the adhesive accumulation part is kept in a space among the chamfers and the outer peripheral face of the shaft member, it is possible to prevent adhesive from going around onto one end face of the thrust member which becomes a thrust bearing face and avoid a defect such as reduction of performance of the thrust bearing.
