Therefore, an injection holehas a curved surface portionE formed between a peripheral edgeI of an inlet openingG and an inner peripheral surfaceF. The curved surface portionE has a center-side curved surface portionAE and an outer-peripheral-side curved surface portionBE. The center-side curved surface portionAE is formed to have a width WAE that is larger than the width WBE of the outer-peripheral-side curved surface portionBE.
