PROBLEM TO BE SOLVED: To provide a packing for an injector which seals a space between an injector for jetting a fuel and a housing including a hole in which the injector is inserted and solves problems such as increase of insertion resistance and protruding of the packing.SOLUTION: An outer peripheral surface of a packing includes a round part between first and second taper parts and closely contacts with a cylindrical wall of a second step part at the housing side. An inner peripheral surface of the packing includes a round part between third and fourth taper parts and closely contacts with a cylindrical wall of a first step part at the injector side. An angle &bgr; formed between the third and fourth taper parts is set larger than an angle α formed between the first and second taper parts. |
