Spindle motor and hard disk drive device

A spindle motor comprising:

• a rotating part configured to rotate about a central axis extending in an axial direction;
• a base member including an inner surface and an outer surface, the base member extending in a radial direction orthogonal to the axial direction and being configured to support the rotating part on an inner surface side;
• a connector to which a component disposed on the inner surface side of the base member is electrically connected;
• and
• a connector accommodating recess formed on the outer surface of the base member,
• wherein the connector accommodating recess includes a bottom surface extending in the radial direction, and an annular wall surface extending in the axial direction from an outer periphery of the bottom surface to the outer surface,
• a through-hole is formed in the axial direction in the bottom surface,
• the bottom surface includes a first annular surface extending toward the annular wall surface from a peripheral edge of the through-hole, and a second annular surface surrounding the first annular surface,
• the connector contacts the second annular surface,
• a first gap between the connector and the first annular surface is filled with an adhesive, and
• an interface of the adhesive, when viewed along the axial direction, extends protruding from an inner peripheral surface of the through-hole over an entire circumference of the through-hole.
