Summary:PURPOSE:To contrive to reduce the cost of a metal mold production, improve the flexibility and prevent the porosity leakage by arranging plural nozzle mounting surfaces on an outer periphery surface of a main body, a gas chamber from one end surface to the other end surface of the main body, a gas feeding hole and a choking means of both end opening parts of the gas chamber. CONSTITUTION:A nozzle holder main body 5 manufactured by a drawing processing is provided with nozzles 7 tightened on nozzle mounting screw holes 6, and a gas feeding hole 9 is located at the outside of a nozzle mounting surface 8, a gas connecting pipe 10 is fitted to the gas feeding hole 9. An opening part 13 manufactured by the drawing processing is choked with a choking plate 12. Thereby, the cost of a metal mold production can be reduced, the flexibility which can freely correspond to the performance of a device can be obtained only with changing of the length, further, a camber on the nozzle mounting surface and a fuel leakage caused by the porosity to be generated at the time of casting can be prevented.
