To provide a cooling structure of an in-wheel motor capable of improving the cooling performance.SOLUTION: A disclosed cooling structure of an in-wheel motor is a cooling structure of an in-wheel motor placed in a wheel of a vehicle. The cooling structure includes: a rotary electric machine that rotates a hub where the wheel is fixed; and a knuckle provided in contact with a stator of the rotary electric machine for rotatably supporting the hub. One or more cooling fins extending in the axial direction of the wheel are provided on the knuckle.SELECTED DRAWING: Figure 3

    【課題】冷却性能の向上を図ることができるインホイールモータの冷却構造を提供すること。【解決手段】本発明のインホイールモータの冷却構造は、車輪のホイール内に設けられたインホイールモータの冷却構造であって、ホイールが固定されるハブを回転させる回転電機と、ハブを回転可能に支持するとともに、回転電機のステータと接触して設けられたナックルと、を備え、車輪の軸線方向に延在する冷却フィンをナックルに1つ以上設けた。【選択図】図3
