In-wheel motor

An in-wheel motor, comprising:

• a motor at least a part of which is disposed inside a wheel and which transmits power to the wheel;
• a cooling device that cools a stator of the motor;
• and
• a brake device that applies a brake to the wheel,
• wherein the brake device includes a brake disc that rotates together with the wheel, and a brake caliper that applies friction to the brake disc for braking,
• wherein the brake caliper operates in an axial direction of the motor to apply a brake to the brake disc,
• wherein a part of an axial end portion of the brake caliper is in contact with the stator,
• wherein the cooling device cools the brake device via the stator,
• wherein the cooling device includes a liquid refrigerant,
• wherein the cooling device includes a first cooling portion through which the liquid refrigerant circulates and a second cooling portion through which the liquid refrigerant does not circulate, and
• wherein the brake caliper is in contact with the first cooling portion via the second cooling portion.
