Solutions Relative with plastic resin short lengthCylindrical tube itself 21 is formed. And,In this tube itself 21, on the other hand (right flank in figure) edgeFrom the edge 22 is lacked ardently in axis direction the engaged portion 23,24 which facilitiesThe ke and others re, in addition, it extends from the edge 25 of another side (left in the figure side)ru engagement section 26,27 is provided. Conspecific tubeIn each engaged portion 23,24 of computer 21a, 21b and 21cTo make each engagement section engage 26,27, that time each person in charge stopping channel 32- Person in charge stopping ring 36a and 36b person in charge entrance are done in 35. TheseConcatenating tube itself 21a, 21b and 21c, embeddingOne body of the length L which responds to tube 14 tube 37 is formedIt is possible ru thing.
