A synthetic resin molded surface fastener comprising: a substrate sheet (1); and a multiplicity of engaging elements (2) molded on a front surface of the substrate sheet (1) for engagement with loops of a companion surface fastener. In the molded surface fastener, each of the engaging elements (2) has a multiple-head structure composed of a single stem (21) standing on the front surface of the substrate sheet (1), two or more necks (22) branching in different directions from an upper end of the stem (21), and two or more substantially straight engaging heads (23) bent outwardly in branching directions from respective outer ends of the necks (22). And each of the engaging heads (23) has on its top (23a) a pair of substantially horizontal protuberances (23a') projecting perpendicularly to an extending direction of each engaging head (23), the top (23a) having a substantially flat top surface (P), each engaging head (23) having a varying thickness gradually decreasing from its base toward its distal end. <IMAGE> |
