Rotary device

A rotary device, comprising:

• a rotatable member configured to be mounted with a recording disk and having an annular recess formed on a surface thereof, the annular recess having a bottom and an inner peripheral portion surrounding the bottom;
• a stationary member rotatably supporting the rotatable member via a dynamic pressure fluid bearing mechanism;
• and
• a circular cap having an outer circumferential edge, the cap being fixed to the rotatable member so as to cover an opening of a gap between the rotatable member and the stationary member;
• and
• a receiving section having a shape to receive an adhesive on an outer peripheral portion of the cap,
• wherein the receiving section includes a notched part formed on the outer circumferential edge, the notched part being dented radially, and an adhesive is applied to the notched part of the cap and the inner peripheral portion.

• a receiving section having a shape to receive an adhesive on an outer peripheral portion of the cap,
• wherein the rotatable member has an annular groove in the bottom, a depth of the annular groove being gradually increased in a radial direction toward the inner peripheral portion, and
• wherein the receiving section includes a first bent part extending in a radial direction along an inner surface of the annular groove, and an adhesive is applied to the first bet part, the annular groove and the inner peripheral portion.
