The at least three protruding portions include: a first protruding portion and a second protruding portion that are disposed so that a midpoint between the first protruding portion and the second protruding portion in a circumferential direction is offset to the high rigidity portion side from a vertical line; and a third protruding portion that is disposed in a region of the low rigidity portion.
