Claims

[Scope of utility model registration request]

A cylindrical space with one end open around the rod-shaped center of the housing is formed, an electromagnetic coil is housed in the space, and a fuel inlet is provided in the cylindrical part on the outer periphery of the coil, and a valve is provided at one end of the housing. The fuel flows out from the nozzle part by electromagnetic opening/closing operation of the housing, and the shape in contact with the terminal hole of the electromagnetic coil on the other side of the housing is formed by two successive conical surfaces of large and small steps, and the taper angle of the large conical surface is A collar formed to be larger than the taper angle of the small conical surface is inserted into the hole through the base of the terminal so that the base is supported on the other side of the housing via an O-ring, and the terminal is attached to the other side of the housing. A fuel injector comprising a connector formed by injection molding so as to integrally cover an exposed part of the housing and the other end of the housing.
