This in-wheel motor fixing structure comprises: an in-wheel motor 2 having a rotor 21 that is fixed to a wheel 1 of a vehicle S and that rotates together with the wheel 1, a stator 22 that is provided inside the rotor 21 and that causes the rotor 21 to rotate by generating a magnetic force while being fixed to the vehicle S, and a shaft 25 fixed to the stator 22 on the rotation axis of the rotor 21 in the stator 22; and a supporting component 3 of the vehicle S having a hole 31 into which the shaft 25 is inserted. A plurality of protrusions 251 formed in the circumferential direction of the shaft 25 are provided in at least a partial region of the shaft 25 in the longitudinal direction, and formed in the inner peripheral surface of the hole 31 are a plurality of recesses 311 into which the plurality of protrusions 251 are respectively inserted.
