PROBLEM TO BE SOLVED: To provide a spacer connecting structure that ensures connecting strength and improves durability. SOLUTION: First to third connecting shafts 18 to 20 are formed on the upper face of the first end 12a of a first spacer 11A. First to third engagement parts 36 to 38 corresponding to the first to third connecting shafts 18 to 20 are formed on the second end 12b of the second spacer 11B. With the first connecting shaft 18 inserted in the insertion hole 40 of the first engagement part 36, the second spacer 11b is rotated counterclockwise around the body 21 of the first connecting shaft 18. Then, the second engagement part 37 and third engagement part 38 are engaged with the second connecting shaft 19 and the third connecting shaft 20 respectively. Since the second end 12b is connected to the first end 12a in three parts by two operations, the connecting strength can be ensured. COPYRIGHT: (C)2007,JPO&INPIT
