ATTACHMENT STRUCTURE OF NOZZLE PLATE FOR FUEL INJECTION DEVICE

[Object] To provide the attachment structure of a fuel injection device nozzle plate capable of reducing the manufacturing man-hours and the manufacturing cost of a fuel injection device. [Solution] A fuel injection device nozzle plate (3) includes a cylindrical fitting part (12) to be fitted onto the front end side of a metal valve body (5) having a fuel injection port (4) and a bottom wall part (14) formed so as to block one end side of the cylindrical fitting part (12), the bottom wall part (14) abutting against a front end surface (13) of the valve body (5) and having a nozzle hole (7). In addition, the cylindrical fitting part (12) and the bottom wall part (14) are made of synthetic resin and formed integrally. The valve body (5) is provided with an outer periphery around which an interlocking projection (8) is formed. An arm part (10) of synthetic resin engaging with the interlocking projection (8) is formed integrally with the cylindrical fitting part (12) and the cylindrical fitting part (12) is fixed to the valve body (5) when the arm part (10) engages with the interlocking projection (8) in the state in which the bottom wall part (14) abuts against the front end surface (13) of the valve body (5).
