In this paper, we analysed,ed theoretically the hunting stability of a bogie truck having a small clearance in the connecting position between the truck frame and the bolster anchor when the spring and friction are connected in series against truck turning. According to the theoretical analysis, we suggest that the exclusion of clearance is extremely important for securing the running stability of high speed railway vehicles, because the hunting velocity may be reduced due to the influence of clearance. Then, the fact that the limit cycle corresponding with the hunting velocity is an unstable limit cycle when there is no clearance is examined. However, on the contrary, there appears to be either a stable limit cycle or an unstable one corresponding to the magnitude of the angular amplitude of the truck frame if there is cleamance in the connecting position between the truck frame and bolster anchor. In the practical analysis, we investigated truck hunting which occurred in an actual car during a SHlNKANSEN running test carried out by the JNR.
