• a rotor unit arranged to rotate about the central axis, the rotor unit including a magnet arranged around the central axis;
• a stator unit including a base member;
• and
• a magnetic member fixed to the base member and axially opposed to the magnet,
• wherein the magnetic member includes an opposing portion axially opposed to the magnet so that a magnetic attracting force is generated between the opposing portion and the magnet and a protrusion portion protruding downwards from the opposing portion, and the base member includes a recess portion, the protrusion portion of the magnetic member being fixed within the recess portion.
