And a reinforcing part protruding on at least one surface of the fastener tape, and the reinforcing part is formed from a plurality of ribs connected to the open separation fitting member, and the rib has a height H of 0.5 to 0.85 mm in the sewing portion to the adherend. A width W of 0.6 to 0.9 mm has a shape in which the end gradually widens from the top to the base, and the ribs of the sewing portion in the reinforcement part are specified by providing a gap portion with a gap wider than the base of the rib between the ribs. Thus, when the reinforcing portion is sewn to the adherend, the ribs can easily escape the impact of the sewing needle to prevent the ribs from being damaged. At the same time, there is an effect that the reinforcement can be accurately and firmly sewn using the gap.

In addition to the above-described configuration, the ribs in the sewing portion of the reinforcement portion are provided with a chamfer at the top portion, and the chamfer portion is formed in an arc shape having a radius of 0.05 to 0.1 mm in cross section, so that the ribs are sewn to the adherend when sewing the reinforcement portion to the adherend. The tip is smoothly evacuated to prevent damage to the rib. The size S of the gap between adjacent ribs in the sewing portion of the reinforcing portion is 2.0 to 2.5 mm, and the ribs at the sewing portion of the reinforcing portion are easily sewn by arranging in parallel in the width direction of the fastener tape. In addition, the reinforcement portion can be effectively used to firmly adhere to the adherend by using the gap portion.

Or the rib of the sewing part in a reinforcement part is represented by the degree of inclination at the base of a rib, tan (theta) = H / (W / 2), and in which tan (theta) satisfy | fills the conditions of 1.1 <= tan (theta) <2.9, and a reinforcement part The rib of the sewing site in the shape of the rib is formed in a shape in which the inclination angle (θ) at the base of the rib falls within a range of 55 ° to 70 °, so that the sewing needle when sewing the rib at the sewing site of the reinforcement part is specified. By the inclined surface of the rib inclined at an angle, the sewing needle can be effectively escaped and effectively sewn together.

In addition, the rib of the sewing part of the reinforcement part is disposed on the side of the open separating fitting member through the auxiliary member, which is the most suitable reinforcement part for the large size slide fastener, and can be effectively sewn to the adherend. Moreover, the rib of the sewing part of a reinforcement part is arrange | positioned directly to the side surface of an open separation fitting member, and is the reinforcement part most suitable for a slide fastener of a small size, and can sew and adhere to an adherend effectively.

In addition, the ribs at the sewing portions of the reinforcement portion are symmetrically disposed on both front and back sides of the fastener tape, so that the ribs can reliably avoid collisions caused by the sewing needle and sew smoothly and firmly even when the fastener tape is sewn from any side. The effect of the present invention is very remarkable.
