The objective of the present invention is to improve the rigidity of a vehicle knuckle made from an aluminum alloy with respect to a force directed from the outside to the inside in the width direction of a vehicle. A vehicle knuckle (11) is provided with a bearing support portion (111), a knuckle upper portion (113) and a knuckle lower portion (112). With the vehicle knuckle (11) in a position fitted to a vehicle main body, the knuckle upper portion (113) has a shape in which, if the knuckle upper portion (113) is divided equally into five or more regions in a vertical direction, and the center of the bearing support portion (111) is fixed and a horizontal load F is applied to a knuckle upper end portion (115) from the outside toward the inside in the width direction of the vehicle, the minimum value of a value obtained by dividing the strain energy in each of the five or more regions other than a first region (11A) by the mass of the corresponding region is at least equal to 0.70 times the maximum value thereof.
