Claims

[Scope of utility model registration request]

A stopper for connecting a corrugated pipe, which has a fitting hole in which a corrugated pipe having spiral irregularities is to be fitted, formed approximately at the center of a plate body, the fitting hole having an outer diameter of the trough of the corrugated pipe. It consists of a superior arc between points S and T of tangents drawn from a fixed point P on the center line of a small circle with a diameter A larger than C and smaller than the outer diameter D of the peak of the corrugated pipe towards the small circle. small circle arc S
The circumference connecting the intersection point Q and R between T and the tangent of a large circle that is concentric with the small circle and has a diameter B that is larger than the outer diameter D of the peak of the corrugated pipe is 3/4 x π x B or less A corrugate having a shape surrounded by an arc QR consisting of a subarc of Stopper for connecting pipes.
