In the second retracted state shown in FIGS. 8 and 9, the branching portion 73 of the resistance bar 7 includes first and second grounding portions 73L and 73R spaced apart from each other in the body width direction. The rod 7 is configured such that the free ends of the first and second grounding portions 73L and 73R are positioned in front of the handle frame 52 when the rod 7 is in the retracted position, and the handle portion 8 and the resistance rod When the walking type electric power management machine 1 is laid down so that the front side 52f of the handle frame 52 faces downward in a state where the 7 is placed in the storage position, the handle portion 8 (handle connection case 80) is lifted from the ground. The moving wheel 6 and the resistance rod 7 are grounded in a state of being positioned above.
Further, even in this case, the battery case 9 is configured to be positioned above the ground in the state where the walking type electric power management machine 1 is laid down.

In this case, as shown in FIGS. 8 and 9, the front side of the handle frame 52 faces downward in the walking type electric management machine 1 in a state where the handle portion 8 and the resistance rod 7 are positioned at the retracted positions, respectively. In this way, the handle portion 8 is brought into contact with the ground by grounding the moving wheel 6 and the first and second grounding portions 73L and 73R of the resistance rod 7 positioned in front of the handle frame 52 in the retracted position. The walking type electric management machine 1 is supported on the ground without being grounded.
Therefore, even if the walking type electric management machine 1 is stored in a lying state, it is possible to prevent the handle portion 8 gripped by the operator from being soiled by grounding.

  Moreover, since the battery case 9 is not grounded in the lying posture, even if the walking type electric management machine 1 is stored in a lying state, an impact is given to the battery case 9 in which the battery 2 is accommodated. This can prevent the battery case 9 from being soiled by grounding.
