Abstract: A case of a disk drive apparatus includes a housing in which a disk is accommodated, and a top cover arranged to close an opening of the housing. The top cover includes a top cover body and a flow control member. The top cover body is a plate-shaped member arranged to extend perpendicularly to a central axis. The flow control member is fixed to a lower surface of the top cover body. The flow control member includes a lower surface arranged axially opposite to at least a portion of an upper surface of the disk.
