PROBLEM TO BE SOLVED: To provide a steering bogie capable of increasing flexibility in designing a steering mechanism.SOLUTION: A steering bogie for rolling stock comprises: a bogie frame that supports a bolster relatively turnably around a vertical axis; two wheel shafts; an axle box supporting device having axle beams which connect the bogie frame and axle boxes in which a bearing supporting an axle of the wheel shafts is housed; and a steering mechanism which steers at least one of the two wheel shafts in response to relative turning of the bolster. The steering mechanism includes: a steering leverage that rotates around a fulcrum axis with respect to the bogie frame; a connection link that connects the bolster and the steering leverage, and interlocks the bogie frame and the bolster relatively turnably; and at least one steering link that steers the wheel shafts by connecting the steering leverage and the axle beams, and displacing the axle boxes via the axle beams while interlocked with rotating operation of the steering leverage. The steering leverage includes shaft parts that rotate around the fulcrum axis. The shaft parts are arranged at a position offset in an axial direction with respect to the steering link.SELECTED DRAWING: Figure 6

    【課題】 操舵機構の設計の自由度を高くすることができる操舵台車を提供する。【解決手段】 鉄道車両用操舵台車は、ボルスタを鉛直軸線回りに相対旋回可能に支持する台車枠と、2つの輪軸と、輪軸の車軸を支持する軸受が収容された軸箱を台車枠に連結する軸梁を有する軸箱支持装置と、ボルスタの相対旋回に応じて2つの輪軸のうち少なくとも一方を操舵する操舵機構とを備える。操舵機構は、台車枠に対して支点軸線を中心に回動する操舵テコと、ボルスタと操舵テコとを連結し、台車枠とボルスタとの相対旋回に連動する連結リンクと、操舵テコと軸梁とを連結し、操舵テコの回動動作に連動して軸梁を介して軸箱を変位させることにより輪軸を操舵する少なくとも1つの操舵リンクとを有し、操舵テコは、支点軸線まわりに回動する軸部を有し、軸部は、操舵リンクに対して軸線方向にオフセットした位置に配置されている。【選択図】 図6
