a third loop-shaped portion in a loop shape positioned at a radially inner side of the second loop-shaped portion, with a second gap between the second loop-shaped portion and the third loop-shaped portion; and
a second connector portion connecting the second loop-shaped portion and the third loop-shaped portion in a part of the second gap;
wherein the second gap is a space between the first end face and the second end face that is configured to store a fluid that has infiltrated between the first end face and the second end face; and
