摘要： In a fuel injection valve supporting structure, a contact surface being orthogonal to a center axis of a fuel injection valve and opposed to a fuel supply cap is formed in an intermediate portion of the fuel injection valve, a supporting member includes a base plate set on the contact surface and an elastic piece extending from the base plate, the elastic piece includes: a first elastic portion extending from the one end of the base plate and bent upwards in a U-shape; and a second elastic portion extending from the first elastic portion toward the other end while bending upwards, bringing its apex into pressure contact with the fuel supply cap, and making a tip end portion thereof slidably come into contact with the base plate, and a curvature radius of the second elastic portion is set larger than a curvature radius of the first elastic portion.
