The surface fastener comprises a pair of upper (male) and lower (female) engaging members (2,3) of the same structures, which are molded integrally and provided with a plurality of rows of hook elements (4) on the surfaces of engaging base plates (21,31). This arrangement unit has successively two hook elements (4,4) of predetermined pitches and a spacing (5) of two pitch lengths and is repeated in order continuously. The spacing (5) means that one hook element is not present. Due to these spacings (5), a hook element (4) of one engaging member is inserted between two hook elements (4,4) of the other engaging member, respective two hook elements (4,4) are easily elastic- deformed in the separating direction to provide reliable engagement of the opposed hook elements (4,4) even if positions of the opposed hook elements do not match perfectly. <IMAGE> |
