PROBLEM TO BE SOLVED: To enhance attachment strength of an exhaust pipe extending in a vertical direction.SOLUTION: A cover member 18 which covers a through-hole 6C and on which an upper side opening 18E is formed is provided to a rear surface 6A of a counterweight 6. A lower end 22B of an exhaust pipe 22 extending in a vertical direction is fixed to a base plate 20 to be attached to the cover member 18. A plurality of pieces of reinforcement plates 24 to be fixed to a top surface 20B of the base plate 20 and to an outer peripheral surface 22C of the exhaust pipe 22 is provided to a lower portion side of the exhaust pipe 22. Accordingly, attachment portions of the exhaust pipe 22 and the base plate 20 can be reinforced by four pieces of the reinforcement plates 24 fixed to the outer peripheral surface 22C of the lower portion side of the exhaust pipe 22 and the top surface 20B of the base plate 20, and attachment strength of the exhaust pipe 22 with respect to the base plate 20 can be enhanced.SELECTED DRAWING: Figure 8

    【課題】 上,下方向に延在する排気パイプの取付強度を高める。【解決手段】 カウンタウエイト6の後面6Aに、貫通孔6Cを覆うと共に上側開口18Eが形成されたカバー部材18を設け、このカバー部材18に取付けられるベース板20には、上,下方向に延びる排気パイプ22の下端22Bを固着し、排気パイプ22の下部側には、ベース板20の上面20Bと排気パイプ22の外周面22Cとに固着される複数個の補強板24を設ける。従って、排気パイプ22とベース板20との取付部位を、排気パイプ22の下部側の外周面22Cとベース板20の上面20Bに固着された4個の補強板24によって補強することができ、ベース板20に対する排気パイプ22の取付強度を高めることができる【選択図】 図8
