Claims

[Claims for Utility Model Registration] 1. A vehicle comprising a truck frame, a side frame bolted to the frame, and a guide mechanism disposed on both sides of the contact surfaces of these frames, the guide mechanism being arranged on the side surface of the truck frame. Consisting of a guide groove provided in the guide groove, a guide pin on the side frame that engages with the guide groove, and a guide plate fixed to the guide pin, the side frame is guided to move linearly by contact between the guide pin and the guide groove. However, in an undercarriage of a construction machine in which a guide plate prevents the frames from separating, and a guide groove positions the bolt holes in both frames, one of the guide mechanisms is attached to the side frame. An undercarriage for a construction machine, characterized in that it is constituted by a guide block made of a member having flat surfaces on opposing sides. 2. The undercarriage body according to claim 1, wherein the guide block is provided with a space or a hole passing through the plane and a plane other than the plane.
