<p>An upper fixing portion for a slide fastener is provided to improve the vertical tensile strength of an upper fixing portion by installing a protrusion that reinforces a protrusion portion and a body. An upper fixing portion(1) is installed in the shape of being connected to a fastener element line(5). A protrusion portion(13) is installed on the inner surface(12) of a body in the shape of protruding in a side direction. A concave portion(14) into which a flange of a slider is inserted is formed. A thin protrusion(15) that is thinner than the protrusion portion is installed on the concave portion. The front end portion of the protrusion is slant in a triangular shape across the connection surface(16) of the protrusion portion and the inner surface of the body. The flange compresses the upper fixing portion by the sliding movement of a slider.</p> |
