Abstract
An in-wheel motor includes a casing at least partly housed in a wheel; a hub rotatable about an axis with a neck portion disposed in the casing and having a first face spline and a flange portion radially expanding outside the casing to combine with the wheel; a stator including an electromagnet for generating a magnetic flux and fixedly supported by the casing; a rotor rotatably supported by the casing and including a shoulder portion having a second face spline to mesh with the first face spline and a disk portion integral with the shoulder portion and radially expanding from the shoulder portion toward the stator to receive the magnetic flux so as to be driven around the axis; and a bolt screwed in the shoulder portion to force the first face spline in close contact with the second face spline.
