The hub unit includes: 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; and a steering actuator separate from the unit support member and configured to rotationally drive the turning shaft-equipped hub bearing. The steering actuator is attached to the suspension device at a position higher than a lowermost surface of the torsion beam and between a rotation support part of the suspension device and the turning shaft-equipped hub bearing.
