When defining the section passing through the deepest point of the concave portion as a first section and defining the section perpendicular to the first section at the deepest point as a second section, the concave portionshave symmetrical shapes on the basis of the first section and have asymmetrical shapes on the basis of the second section. When defining the directions along the first section in the concave portionsas axis directions L, L, each of the axis directions L, Lare not parallel with the arrangement direction, and the axis directions L, Lare set to two or more directions.
