2. Description of the Related Art Generally, as shown in FIG. 5, in a counterbalance type forklift, a rear end of a vehicle body 2 is provided so that when a load is placed on a fork 1, the rear portion of the vehicle body 2 does not rise and lose balance. A weight 3 made of a casting or the like is attached to the portion. Conventionally, to attach such a weight 3 to the vehicle body 2, as shown in FIG. 6, a plurality of bolts 5 are projected from four rear, upper, lower, left and right portions of a rear end of a rear frame 4 of the vehicle body 2, while 3, bolt insertion holes 3 a are formed at positions corresponding to the respective bolts 5, and the bolts 5 are inserted into the respective bolt insertion holes 3 a while the weight 3 is hung by a crane or the like, and are fixed with nuts 6. ing. Therefore, the conventional one has a structure in which the entire weight of the weight 3 is directly supported by the bolt 5. Here, when attaching the weight 3 to the rear frame 3 as described above, the weight 3
It is necessary to keep the weight as low as possible, and since the head guard 7 is attached to the upper part of the weight 3, the weight 3 needs to be kept as horizontal as possible to the ground.

However, since the weight 3 is manufactured by casting, the shape of each product slightly varies. Therefore, when the weight 3 is in a horizontal state, the weight between the rear frame 4 and the weight 3 is small. May cause a slight gap. Then, when such a gap is formed, the shim 8 is inserted into the gap to prevent the weight 3 from rattling.

[0004]

By the way, if the weight 3 is directly supported by the bolts 5 as in the prior art, the load applied to the bolts 5 is large, and the bolts 5 become fatigued or corroded. Once the bolt 5 is damaged, the weight 3 is
It is not sufficient in terms of safety because it may cause accidents such as dropping off. When the weight 3 is attached, the weight 3 is suspended by a crane or the like to adjust the weight 3 to be horizontal. At this time, the weight 3 has a gap between the bolt hole 3a and the bolt 5. The shim 8 is inserted into a narrow space between the rear frame 4 and the weight 3 because the shim 8 swings by an amount, so that there is a great risk that the finger may be jammed when the shim 8 is inserted.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to enhance the safety when a weight is attached to the rear end of a vehicle body and to minimize the danger when attaching the weight. It is an object of the present invention to provide a weight mounting structure in such a counterbalance type forklift weight.
