A hub unit (1) having a steering function is equipped with: a hub unit main body (2) having a hub bearing (15); a unit support member (3) that is provided on an undercarriage frame component (6), and that supports the hub unit main body (2) so as to be rotatable around a steering axis center extending in the vertical direction; and a steering actuator (5) for driving the hub unit main body (2) so as to rotate around the steering axis center. Steering shaft parts (16b, 16b), both of which protrude in the vertical direction, and the axial center of which serves as the steering axis center, are integrally provided on an outer circumferential surface of an outer ring (19) of the hub bearing (15), and the hub unit main body (2) is rotatably supported on the unit support member (3) through the steering shaft parts (16b, 16b).

    带有操舵功能的轮毂单元(1)包括:轮毂单元主体(2),该轮毂单元主体(2)具有轮毂轴承(15);单元支承部件(3),该单元支承部件(3)设置于行走部分支架部件(6)上,以绕沿上下方向延伸的转向轴心而自由旋转的方式支承轮毂单元主体(2);操舵用致动器(5),该操舵用致动器(5)使轮毂单元主体(2)绕转向轴心而旋转驱动,在轮毂轴承(15)的外圈(19)的外周面上一体地设置有分别沿上下方向突出且轴心成为上述转向轴心的转向轴部(16b、16b),轮毂单元主体(2)经由转向轴部(16b、16b)而自由旋转地支承于单元支承部件(3)上。
