A third inclined surface located between the first and second inclined surfaces, facing the first inclined surface, inclined such that a distance between the third and first inclined surfaces decreases downward in the vertical direction, and having a first gap with respect to the first inclined surface is provided. A fourth inclined surface located between the first and second inclined surfaces, facing the second inclined surface, inclined such that a distance between the fourth and second inclined surfaces decreases downward in the vertical direction, and having a second gap with respect to the second inclined surface is provided.
