Abstract

DC60, tubular part 1 of the mouthpiece, but has one or more first protrusions 21, one or more radial protrusions, and one or more 22 second protrusions at the phase position. Unlike the first overhang 21 in the axial direction and in the circumferential direction on the outer perimeter, each overhang 21 and 22 are formed in such a way that the surface On the side of the trumpet-shaped opening, 3 undergoes a very steep inclined surface 2a, while the surface On the side of the pipe-shaped opening section 4, a least inclined surface layer 2b is formed, the axial phase w between the first overhang 21 and the second overhang 22 is determined according to the W is less than or equal to W relative to the axial width W of the inner perimeter of the section. The small diameter 32 in corrugated pipe P, the phase angle along the circumference r, is assigned to be significantly equal to the obtained value by calculating by dividing the semicircular angle (180 degrees). Number of first protrusions 21 tubular part 1 of the mouthpiece per profile but has one protrusion. 21 One or more parts that extend radially. And the second filing 22, one or more parts that extend at The position with the phase differs from the first protrusion 21 in the axial direction and in the circumferential direction. On the outer perimeter, each overhang 21 and 22 are formed in such a way that the lateral surface of the trumpet opening section 3 is formed into a steep incline. More 2a, while the side surface of the pipe opening section 4 is formed as an inclined surface layer at least 2b, the axial phase w between the first overhang 21 and the second overhang 22 is obtained. Get defined in accordance with the relationship: w is less than or equal to W. In relation to the axial width W of the inner perimeter of the small diameter section 32 in the annular corrugation tube P, the phase angle along the circumference r is set to be equal to the value obtained by Calculation by dividing the semicircular angle (180 degrees) by the number of the first overhang 21:
