An in-wheel motor drive device (1) comprises a hub (10) to which a wheel (3B) is attached, an electric motor (11) disposed coaxially on the hub (10) on the inner side with respect to the width direction of a vehicle (4), a motor housing (13) that houses the electric motor (11), and a brake caliper (18) that clamps a brake disk (15) with a pair of brake pads (16) disposed on both sides of the brake disk (15). The brake caliper (18) is secured to the outer periphery of the motor housing (13) by the screwing-in of a bolt (32) from the radial direction outside to the radial direction inside of the motor housing (13). |
