A group of partition-cylinder small holes is formed in the partition cylinder, and a group of inner-cylinder small holes is formed in the inner cylinder. The group of partition-cylinder small holes and the group of inner-cylinder small holes do not overlap each other in an axial direction, and are separated from each other by a predetermined distance in the axial direction.
