Claims

[Scope of utility model registration request]

A male claw strip having a roughly mushroom-shaped cross section is provided on one of the opposing surfaces to be fastened to each other, and a mushroom-shaped head of the male claw strip is provided on the other opposing surface and has a cross-sectional shape. In a synthetic resin fastener consisting of a female claw strip that surrounds the male claw strip and has a hook at the tip that engages with both sides of the head, the width of one of the male claw strip or the female claw strip. A small convex strip that protrudes toward the other strip is provided in the center of the direction,
The other strip is provided with a concave groove in which the small convex strip and both inner surfaces fit together when the zipper is closed, and the small convex strip is a male claw strip or a female claw provided with the small convex strip. A synthetic resin fastener characterized by being provided so as to protrude from the tip of the strip.
