PROBLEM TO BE SOLVED: To simplify attachment work and enable easy detachment. SOLUTION: An attachment tool 10 is made of a synthetic resin and is integrally molded. A shaft part 12 having a square cross-section is extended from the central part of a head part 11. The tip part of the shaft part 12 is divided into two directions, to form a Y-shape consisting of flexible leg parts 13a and 13b which have hook parts 14a and 14b on their tip parts respectively. Hook parts 14a and 14b have inclined parts 15a and 15b on their front ends, and the inclined parts 15a and 15b are so formed as to form an approximately gimlet shape together, when the leg parts 13a and 13b are closed. Retainers 16a and 16b having surfaces approximately vertical to the longitudinal direction of the shaft part are formed on the rear ends of the hook parts 14a and 14b. Further, a circular pressing plate 17 is put on the shaft part 12 between the head part 11 and the leg parts 13a and 13b. Parts of the pressing plate 17 on the both sides of its shaft part 12 insertion hole are linked with the rear ends of the hook parts 14a and 14b with flexible linking pates 19a and 19b. |
