To provide a method by which a contact of a top plate with a step member is prevented.SOLUTION: Even if a top plate part 50 is deformed in an emergency, in order to avoid the top plate part damage caused by contacting with a step member 30 or the difficulty of the member's movement when the member goes in and out, a support roller 60 is a component installed for supporting the deformed top plate part 50. In the concrete, the support roller 60-2 is installed in the step member 30 as a component for keeping a clearance between the step member 30 taken in and out from the housing 20 and the top plate 52 of the housing 20 equal to or wider than a prescribed width even in the case the top plate 52 is deformed.The support roller 60-2 is installed at a position which the step member 30 attains vertically under the end part 522 of the top plate 52 in a projecting direction A1 in the condition the step member 30 projects most from the housing 20.SELECTED DRAWING: Figure 9

    【課題】天板とステップ部材の接触を防止すること。【解決手段】支持ローラ60は、万が一天板部50が変形しても、ステップ部材30に接触して傷ついたりステップ部材30の出し入れに支障が出たりしないように、変形した天板部50を支持するために設けられた部材である。具体的には、支持ローラ60−2は、筐体20から出し入れされるステップ部材30と筐体20の天板52との隙間を、天板52が変形した場合でも所定量以上に維持する部材として、ステップ部材30に設けられている。支持ローラ60−2は、ステップ部材30が筐体20から最も張り出した状態のときに、天板52の張出方向A1の端部522の鉛直下方に到達する位置に設けられている。【選択図】図9
