A hub unit (1) having a steering function according to the present invention comprises: a hub unit body (2); a unit support member (3) that is provided on a knuckle (6) to rotatably support the hub unit body (2) around a steering axis (A) extending in a vertical direction; and a steering actuator (5) that rotates the hub unit body (2) around the steering axis (A). The steering actuator (5) has a motor (26) and a linear motion mechanism (25) that converts a rotation output of the motor (26) into a linear motion, the linear motion mechanism (25) has a sliding screw-type feeding screw mechanism (33) including a nut part (36) and a screw shaft (36), and a surface hardening treated layer is provided on at least a screw surface of one or both of the nut part (35) and the screw shaft (36).

    本发明的带有操舵功能的轮毂单元(1)包括:轮毂单元主体(2);单元支承部件(3),该单元支承部件(3)设置于转向节(6)上,以围绕沿上下方向延伸的转舵轴心而自由旋转的方式支承轮毂单元主体(2);操舵用促动器(5),该操舵用促动器(5)使轮毂单元主体(2)围绕转舵轴心(A)而旋转。操舵用促动器(5)具有马达(26)和直线运动机构(25),该直线运动机构(25)将马达(26)的旋转输出转换为直线运动,该直线运动机构(25)包含具有螺母部(36)和丝杠(36)的滑动丝杠式的进给丝杠机构(33),在螺母部(35)和丝杠(36)的任意一者或两者的至少螺纹面上设置有表面硬化处理层。
