The present embodiment is configured as described above. Therefore, when the counterweight 1 is attached to the vehicle body, first, the engaging recess 2a of the horizontal portion 3 of the counterweight 1 hung by a crane or the like is projected by the support member 5. It is placed on the upper part of the vehicle body so as to engage with the portion 6. This makes the vertical part 3
Since the through hole 9 of is aligned with the screw hole 12 of the fixing member 7,
When the fastening bolt 8 is inserted into the through hole 9 of the vertical portion 3 in this state and the handle 16 of the screwdriver 14 is turned to screw the screw portion 8a into the screw hole 12 of the fixing member 7, only the fastening bolt 8 is removed. The screw springs against the tension spring 21. After the rubber sheet 13 comes into contact with the hole edge of the through hole 9, the rubber sheet 13 is compressed and rotated to tighten the handle 16 until the handle 16 becomes horizontal. That is, the elastic force of the rubber sheet 13 is used to make the handle 16 correspond to the notch 11 for storage, and then the tension spring 21 is used to store the handle 16 in the notch 11 as shown in FIG. For example, the engagement between the handle 16 and the notch 11 prevents the tightening bolt 8 from loosening. Although the looseness of the tightening bolt 8 can be suppressed to some extent also by the rubber sheet 13, it can be made more reliable by the engagement between the handle 16 and the notch 11.
