ABSTRACT:
To provide a counter weight capable of forming an attaching part to a vehicle frame with high precision, capable of improving attaching precision to this vehicle frame, and further, capable of decreasing a manufacture cost thereof. The counter weight includes a base made of cast iron having an attaching part, whereby the counter weight is attached to a vehicle frame; and a weight part made of a slab material having a block body made of a slab material; wherein the weight part made of the slab material is attached on the above-described base made of cast iron. The outer surface of the above-described weight part made of the slab material is coated with the cover. In addition, the connection plate is attached to the above-described base made of cast iron, the lower end edge of the above-described cover is joined to the base made of cast iron through the above-described connection plate, and the upper end edge of the above-described cover is joined to the upper part of the above-described weight part made of the slab material. Since the base made of cast iron is attached to the vehicle frame, it is possible to form the attaching part to the vehicle frame at a low cost, simply, and with high precession.
