To prevent damage to a power source-side connector caused by dropping it.SOLUTION: An upper rotating body 3 of an electric hydraulic excavator 1 is equipped with an electric motor 13 serving as a power source, and a vehicle body-side power supply cable 17 that supplies power to the electric motor 13. A power source-side power supply cable 19, which is connected to an external power source, is electrically connected to the vehicle body-side power supply cable 17. A vehicle body-side connector 18 is provided on the vehicle body-side power supply cable 17. A power source-side connector 20, which is detachably connected to the vehicle body-side connector 18, is provided on the power source-side power supply cable 19. A connector holding device 27 is provided between the upper rotating body 3 and the power source-side connector 20. The connector holding device 27 holds the power source-side connector 20 in a position away from the vehicle body-side connector 18 with a connection port 20B of the power source-side connector 20 facing a connection port 18B of the vehicle body-side connector 18.SELECTED DRAWING: Figure 8
【課題】電源側コネクタの落下による破損を防止する。【解決手段】電動式油圧ショベル１の上部旋回体３は、動力源となる電動モータ１３と、電動モータ１３に電力を供給する車体側給電ケーブル１７とを備え、車体側給電ケーブル１７には、外部電源に接続された電源側給電ケーブル１９が電気的に接続される。車体側給電ケーブル１７には車体側コネクタ１８が設けられ、電源側給電ケーブル１９には、車体側コネクタ１８に着脱可能に接続される電源側コネクタ２０が設けられ、上部旋回体３と電源側コネクタ２０との間には、コネクタ保持装置２７が設けられる。コネクタ保持装置２７は、電源側コネクタ２０の接続口２０Ｂと車体側コネクタ１８の接続口１８Ｂとを対向させた状態で、電源側コネクタ２０を車体側コネクタ１８から離れた位置に保持する。【選択図】図８
