OPENING/CLOSING BODY OPENING/CLOSING DEVICE
PROBLEM TO BE SOLVED: To provide an opening/closing body opening/closing device which can efficiently adjust tension of a transmission belt without increasing manufacturing man-hours.SOLUTION: A pair of driven pulleys round which an endless toothed belt 36 is wound are arranged at both ends of a step panel 17 in a fore-and-aft direction, respectively. A pair of support wall parts 42, 43 in which concentric insertion holes 44, 45 are formed and which are arranged oppositely to each other, is arranged at a rear end of the step panel 17. An opening/closing body opening/closing device includes a support pin 50 having a first end 51 and a second end 52 which are formed at both ends in the axial line direction, and inserted into both the insertion holes 44, 45, respectively, and a shaft part 53 which is formed at an intermediate part in the axial line direction sandwiched between both the support wall parts 42, 43, and rotatably supports the driven pulleys 34. The shaft part 53 is decentered with respect to the first end 51 and the second end 52.
【課題】製造工数を増大することなく、伝動帯の張力を効率よく調整することができる開閉体開閉装置を提供する。【解決手段】ステップパネル１７の前後方向両端部には、無端歯付ベルト３６が巻き回しされる一対の従動プーリがそれぞれ配置されている。ステップパネル１７の後端部には、互いに同心の挿通孔４４，４５が形成されて互いに対向配置された一対の支持壁部４２，４３が設けられている。軸線方向両端部に形成され両挿通孔４４，４５にそれぞれ嵌挿された第１端部５１及び第２端部５２と、両支持壁部４２，４３に挟まれる軸線方向中間部に形成され従動プーリ３４を回転可能に支持する軸部５３とを有する支持ピン５０を備え、軸部５３は、第１端部５１及び第２端部５２に対して偏心している。【選択図】図２
