Abstract

PURPOSE: To maintain a hermetic effect by having racial hermetic tongue bodies of an annular shape and roof shape smaller than a scraper body at both ends of a portion having a small diameter. CONSTITUTION: This scraper body consists of coaxial spherical members 12 and 13 and a central constriction part of an area 14. The smallest diameter of the central constriction part of the area 14 is so determined as not to come into contact with the wall surface of the curvilinear part of the smallest pipeline. Columnar parts 15 and 16 exist between the constriction part of the area 14 and the spherical parts 12 and 13. The columnar parts 15 and 16 are internally provided with annular grooves 17 and 18 of a rectangular shape in the cross-section. Annular sealing members 20 and 21 are housed in the annular grooves 17 and 18 and the annular grooves are internally provided with recessed parts 22 and 23 apart a spacing in a circumferential direction. Permanent magnets 24 are housed in the recessed parts 22, and 23 and act as detectors. As a result, a scraping effect is improved.
