Zusammenfassung:	PURPOSE:To reduce lateral pressure of a front shaft outer track side at the time of passing a curved railway by switching for control steering device supporting rigidity, which uses front and rear asymmetric rigidity supporting method, of a front shaft side and a rear shaft side separately. CONSTITUTION:Air springs 5 of a front shaft 3 side and air springs 6 of a rear shaft 4 side of a front truck 1 and a rear truck 2 are connected respectively by separate pipelines 7, 8, and they are connected to a main air reservoir 14 by a pipeline 15 through solenoid valves 9, 10. The solenoid valves 9, 10 are switched by a forward and backward switching relay 11. Supporting rigidity of the front shaft side and the rear shaft side are separately controlled. Consequently, a steering device is operated effectively by a simple control equipment in response to the condition of a track.
