The protruding edge section of the first opening portion and the recessed edge section of the second opening portion are provided at positions corresponding to each other in the direction around the axis. The recessed edge section of the first opening portion and the protruding edge section of the second opening portion are provided at positions corresponding to each other in the direction around the axis.
