Abstract

PURPOSE: To prevent detachment of pins driven into the solid cylindrical main body of a stopper for cleaning the inside of a pipeline by providing nonpartible projections to the middle parts of the shaft parts excepting the tips of the pins consisting of the shaft parts and the head parts.
CONSTITUTION: In a stopper 1 propelled in a pipe by fluid pressure which has been inserted into the pipe, the solid cylindrical main body 2 is formed by a rigid elastic material (e.g. high-density urethane foam). Furthermore many pins 3 made of rigid material whose head parts 6 remain on the outer peripheral face of the main body 2 are driven toward the direction of the center line of the cylinder at the intervals with each other from the outer periphery of the main body 2. The nonpartible projections 5 are provided to the middle parts of the shaft parts 4 excepting the tips of the pins 3 consisting of the shaft parts 4 and the head parts 6. As a result, detachment of the pins driven into the solid cylindrical main body of the stopper for cleaning the inside of a pipeline can be prevented.
