An integrally molded surface fastener which promotes high manufacturing efficiency, assures easy stock control and easy attachment in the shipment, and provides high engaging strength and stable form without deterioration of engaging and holding force even when being used repeatedly. The surface fastener comprises a pair of upper (male) and lower (female) engaging members of the same structures, which are molded integrally and provided with a plurality of rows of hook elements on the surfaces of engaging base plates. Then, this arrangement unit has successively two hook elements of predetermined pitches and a spacing of two pitches length and is repeated in order continuously. The spacing means that one hook element is not present. Due to the spacing, a hook element of one engaging member is inserted between two hook elements of the other mating engaging member, respective two hook elements are easily elastic-deformed in the separating direction to provide reliable engagement of the opposed two hook elements even if positions of the opposed hook elements do not match perfectly. |
