SOLUTION: This injector 1A injects and supplies the gaseous fuel to the intake passage of the engine by being mutually connected in series and in a side feed type by fuel connecting pipes 50. A pair of connecting holes 12 and 13 having connecting structures for connecting the inside of each of the fuel structure pipes 50 and the inside of a yoke 1a by being connected to the fuel connecting pipes 50 are provided at side face diagonal positions of the yoke 1a to be a body casing. The yoke 1a serves as also an injector housing to constitute the fuel gallery. A fuel passage formed between an inner peripheral surface of the yoke 1a and an outer peripheral surface of an injector driving mechanism 16 serves as also a gallery chamber 10a to be a part of the fuel gallery.
