<p>PROBLEM TO BE SOLVED: To easily pass a pipe-through material through a pipe, even if a cable is already in the pipe. SOLUTION: An adapter 10 is composed of a cylindrical first junction member 12 which is put on the end section of interior piping and made of a sponge rubber, a second junction member 14 which is inserted into the sucking opening of an aspirator and made of the sponge rubber, and a coupling pipe 16 which couples the members 12 and 14 with each other. The first junction member 12 has a slit 18 formed along the axial direction of the member 12, so that an already existing cable coming out of the piping is held in the slit 18. In addition, the coupling pipe 16 is made of a transparent material, such as a plastic material, etc., such that the arrival of a wind-receiving member can be confirmed visually.</p> |
