A steering function-equipped hub unit for steering a rear wheel of a vehicle, which is configured to be supported by a suspension device including a torsion beam and a pair of trailing arms, the steering function-equipped hub unit comprising:

• a turning shaft-equipped hub bearing including a turning shaft extending in a vertical direction and configured to rotatably support the rear wheel;
• a unit support member supporting the turning shaft-equipped hub bearing such that the turning shaft-equipped hub bearing is rotatable about a turning axis of the turning shaft;
• and
• a steering actuator separate from the unit support member and configured to rotationally drive the turning shaft-equipped hub bearing about the turning axis, wherein
• the steering actuator is attached to the suspension device at a position higher than a lowermost surface of the torsion beam of the suspension device and between a rotation support part of the suspension device and the turning shaft-equipped hub bearing.
