Abstract
A washer-equipped screw is provided with a screw body, a flat washer, and a rubber washer. The screw body includes a cylindrical portion between a shaft portion on which a screw groove is formed and a head portion. A hole in the flat washer is inserted through the cylindrical portion so as to be adjacent to the head portion. A hole in the rubber washer is inserted through the cylindrical portion and positioned on a shaft portion side of the flat washer. The cylindrical portion is provided with a projection for engagingly locking the flat washer. An inner edge of the flat washer is caught by the projection, whereby the flat washer is prevented from detaching.
