PROBLEM TO BE SOLVED: To provide a steering bogie for a rolling stock, which smoothly passes a curved track having a changing radius of curvature like a relaxing curve. SOLUTION: This steering bogie imparts a mechanical linking mechanism between a plurality of wheel axes to impart linking in motions between the wheel axes. The steering bogie includes a bogie frame for holding the wheel axes via an axle box and an axle box support device and a bolster for supporting a vehicle body on two bolster springs arranged on both ends in the longitudinal direction by interposing the two bolster springs. The steering bogie includes a rotation support mechanism for rotatably supporting the bolster on the bogie frame after separating the bogie frame and the bolster to be opposed in substantially parallel. The rotation support mechanism is imparted between the bolster and the bogie frame at the center in the longitudinal direction of the bolster. COPYRIGHT: (C)2011,JPO&INPIT
