PROBLEM TO BE SOLVED: To reduce a size and weight of a revolving superstructure by reinforcing structure of an attachment part of a pattern changeover valve of a driver's seat pedestal.SOLUTION: A changeover valve bracket 30 which is located at an inside face 12G4 being an engine 8 side, and to which a pattern changeover valve 29 is attached, is provided at an entrance 20 side of a driver's seat pedestal 11. In the changeover valve bracket 30, an attachment region 30B at the driver's seat pedestal 11 side abuts on the inside face 12G4 of the driver's seat pedestal 11. On the other hand, one end region 34B of a handrail member 34 opposes the attachment region 30B of the changeover valve bracket 30, and abuts on an outside face 12G5 of the driver's seat pedestal 11. By this constitution, the attachment region 30B of the changeover valve bracket 30 and one end region 34B of the handrail member 34 are fastened to each other with bolts 35 with the driver's seat pedestal 11 sandwiched therebetween.SELECTED DRAWING: Figure 7
【課題】 運転席台座のパターン切換弁の取付部の構造を強化することにより、上部旋回体の小型化、軽量化を図る。【解決手段】 運転席台座１１の乗降口２０側には、エンジン８側となる内側面１２Ｇ４に位置してパターン切換弁２９を取付けるための切換弁ブラケット３０が設けられる。切換弁ブラケット３０は、運転席台座１１側の取付部位３０Ｂが運転席台座１１の内側面１２Ｇ４に当接されている。一方、手摺り部材３４の一端部位３４Ｂは、切換弁ブラケット３０の取付部位３０Ｂと対面して運転席台座１１の外側面１２Ｇ５に当接されている。この上で、切換弁ブラケット３０の取付部位３０Ｂと手摺り部材３４の一端部位３４Ｂとは、運転席台座１１を挟んだ状態でボルト３５を用いて締着する構成としている。【選択図】 図７
