摘要： A motor unit (21) of an in-wheel motor drive device (10) is offset from the axis (O) of a hub wheel. A brake caliper (40) is offset from the axis (O) so as not to overlap the motor unit (21) as viewed in the direction of the axis (O) and is attached and fixed to a casing serving as an outer shell of the in-wheel motor drive device (10) by attachment members (44, 45) at two positions separated in a circumferential direction about the axis (O). The attachment members (44, 45) are disposed in such a manner that a part of each attachment member (44, 45) overlaps the outer circumferential edge of a brake rotor (50) as viewed in the direction of the axis (O).
