  • Publication number: 20130220276
    Abstract: In a fuel injection valve supporting structure, a first contact surface being orthogonal to a center axis of a fuel injection valve and opposed to a fuel supply cap and paired second contact surfaces opposed to each other with a plane, including the center axis and a center line of a coupler, in between are formed in an intermediate portion of the fuel injection valve, and a supporting member includes: a base plate set on the first contact surface; an elastic piece extending from the base plate to elastically come into pressure contact with the fuel supply cap and bias the fuel injection valve toward an injection valve attachment hole by its reaction force; and paired turn stopper pieces each extending from the base plate to abut against the second contact surface and restrict a turn of the fuel injection valve about the center axis.
