Abstract
Official abstract text for this publication.
The molded surface fastener includes: a fastener member that has a plurality of engagement elements disposed upright on the first surface of a base portion, and a back member that is secured to the second surface of the fastener member and that is provided with a structure enabling passage of a synthetic resin. The base portion has a first base region of a predetermined thickness and a second base region formed to be thicker than the first base region, and the back member is secured to at least the second base region of the base portion. The adhesion strength of the back member to the fastener member is thus increased, enabling the back member to be held more firmly by the base portion.

The invention claimed is: 1. A molded surface fastener includes: a fastener member made of a synthetic resin; and a back member formed separately from the fastener member, in which the fastener member has a plate-shaped base portion provided with a first surface and a second surface, and a plurality of engagement elements provided to the first surface of the base portion, and the back member is secured to the second surface of the base portion, wherein the back member has a structure enabling the synthetic resin to pass from a first surface to a second surface of the back member or a structure enabling the synthetic resin to penetrate into the back member, the base portion has a first base region of a predetermined thickness and a second base region formed to be thicker than the first base region, the back member is secured to at least the second base region of the base portion, the fastener member has left and right outer wall portions disposed upright along a longitudinal direction of the base portion, the left and right outer wall portions are arranged on an outside, in a width direction, of the region where the plurality of engagement elements are formed, the second base region is formed in only a region on an outside of the left and right outer wall portions with respect to the width direction of the base portion, and the back member is held in a non-secured state in a region inside of the left and right outer wall portions. 2. The molded surface fastener according to claim 1 , wherein a dimension of the second base region in the thickness direction is set smaller than a dimension of the engagement elements in the thickness direction from the first surface of the base portion. 3. The molded surface fastener according to claim 1 , wherein the back member is held in a non-secured state with respect to the first base region. 4. The molded surface fastener according to claim 1 , wherein the second base region has a certain thickness along the longitudinal direction of the base portion. 5. The molded surface fastener according to claim 1 , wherein at least one of a recess and a protrusion is provided to the second base region.
