PROBLEM TO BE SOLVED: To enhance design freedom of an injection hole position, in an injector for an internal combustion engine having injection holes having different specifications.SOLUTION: Outside a bottomed cylindrical inner body 1 in which a communication hole 12 circulating high-pressure fuel is formed, a cylindrical outer body 3 is arranged in a rotatable manner to the inner body 1. In the outer body 3, plural kinds of injection holes 31, 32 having different specifications are formed, and the plural kinds of injection holes 31, 32 is selectively communicated with the communication hole 12 according to the rotation position of the outer body 3. Consequently, the plural kinds of injection holes 31, 32 can be arranged without being displaced to the axial direction of an injector, and design freedom of the injection hole position can be enhanced.SELECTED DRAWING: Figure 2 |
