• and
• a direction changing portion that is provided on an inner surface of the housing and that changes a flow direction of the liquid medium scattered by the rotating body toward the supply target portion, and
• the direction changing portion includes:
• a collecting portion that is gradually inclined toward a downstream side in a rotation direction of the rotating body so as to be separated from an outer periphery of the rotating body and that receives the liquid medium scattered by the rotating body;
