摘要： A spindle motor for use in a disk drive apparatus includes stationary and rotating portions. The stationary portion includes a shaft including a thrust plate. A sleeve portion includes an axial end surface arranged opposite the thrust plate. A first seal member is arranged opposite the thrust plate on an opposite side with respect to the sleeve portion. The thrust plate preferably includes a plate communicating hole arranged to connect first and second thrust gaps defined, respectively, between the thrust plate and the sleeve portion and between the thrust plate and the first seal member. The sleeve portion preferably includes a sleeve communicating hole arranged to connect the first thrust gap with an opposite axial side thereof. A lubricant is arranged to fill a communicating channel extending from a first to a second capillary seal portion through the plate communicating hole and the sleeve communicating hole.
