PROBLEM TO BE SOLVED: To provide a steering bogie having a light-weight and simple link mechanism.SOLUTION: A steering bogie comprises: a bogie frame rotatably supporting a rolling stock body in a yawing direction via a bolster beam or not via the bolster beam; a pair of wheel shafts which each have an axle extending along a rolling stock width direction and wheels provided on both sides of the axle, and which are arranged to be separated in a rolling stock longitudinal direction; an axle box which houses a bearing for supporting each axle; an axle box support device having an axle beam extending from the axle box and connected to the bogie frame via an elastic member; and a link mechanism which is provided in conjunction with the rotation of the bogie frame with respect to the rolling stock body, and which steers at least one of the wheel shafts by displacing the axle box via the axle beam. The axle beam includes: a bogie frame connection part connected to the bogie frame via the elastic member; and a link connection part arranged at a position offset in the rolling stock width direction with respect to the bogie frame connection part, and connected to the link mechanism via a connection member. The connection member and the elastic member are arranged concentrically with each other.SELECTED DRAWING: Figure 1

    【課題】リンク機構が軽量かつ簡素である操舵台車を提供する。【解決手段】操舵台車は、枕梁を介して又は枕梁を介さずにヨーイング方向に車体を回動可能に支持する台車枠と、車幅方向に沿って延びる車軸及び車軸の両側に設けられた車輪をそれぞれ有し、車両長手方向に離間して配置される一対の輪軸と、各車軸を支持する軸受を収容する軸箱と、軸箱から延びて、弾性部材を介して台車枠に連結される軸梁を有する軸箱支持装置と、車体に対する台車枠の回動に連動し、軸梁を介して軸箱を変位させることで少なくとも一方の輪軸を操舵するリンク機構と、を備え、軸梁は、台車枠に弾性部材を介して連結される台車枠連結部と、台車枠連結部に対して車幅方向にオフセットした位置に配置され、リンク機構に連結部材を介して連結されるリンク連結部と、を有し、連結部材及び弾性部材は互いに同心となるように配置されている。【選択図】図1
