The idler (5) is supported by the idler spindle (6) between the idler bogies (3) and (3), and the impact applied to the idler (5) is generated between the idler yoke (2) and the idler bogie (3). It is relieved by the idler cushion (7) installed between them. The tip of the track frame (1) is extended to the lower surface of the idling bogie (3) and a lower wheel skirt (8) is bolted to the lower part thereof for the purpose of preventing the intrusion of sediment.
