The restraint plate is provided with a first hole portion into which the first protruding portion is inserted. The first protruding portion is divided into a first protrusion and a second protrusion in a second direction. The first protrusion is disposed closer to the center of the facing surface in the second direction. The second protrusion is disposed closer to an outer edge of the facing surface in the second direction.
