Abstract

A motor of a disk drive includes a stationary portion, a bearing portion attached to the stationary portion, and a rotating portion supported by the stationary portion to be rotatable about a central axis through the bearing portion. The stationary portion includes a stator in which multiple coils annularly extend around the central axis, and a base portion located below the stator. The base portion is a portion of a housing that defines an internal space accommodating the rotating portion, the bearing portion, and the stator. The base portion includes a through hole that guides a lead drawn from the coil from the internal space of the housing to the outside. The through hole is filled with an adhesive, and includes an inclined hole that is inclined axially downward.
