PROBLEM TO BE SOLVED: To provide an opening and closing body, reducing the manufacturing cost and facilitating assembling. SOLUTION: The tip of an adjusting bolt 21 is passed through a penetrating hole 34 of a traveling member 31. A horizontal roller 36 is rotatably passed through a rotating shaft part 26 of the adjusting bolt 21. An operating member 37 having a regular hexagonal outer peripheral surface is engaged with an engagement part 25 having a rectangular section of the adjusting bolt 21. A male screw part 23 of the adjusting bolt 21 is engaged with a female screw part in a fitting groove 16 of an upper connecting member 14. The space between the traveling member 31 and the upper connecting member 14 can be adjusted by the adjusting bolt 21. The assembling of the traveling member 31 and the upper connecting member 14 can be facilitated. The male screw part 23 and the engagement part 25 of the adjusting bolt 21 can be reduced in a difference of outside diameter. COPYRIGHT: (C)2004,JPO&NCIPI
