クルである。 In other words, as mentioned above, conventional nuts and bolts have a complex shape in order to perform various functions such as fixing the wheel axle, connecting the steering arm, and fixing the support for the brake system, and also have a structure that supports the weight of the vehicle. The braking device support and the knuckle body are formed by casting, which has the necessary strength as a part, but in the present invention, the support of the brake device and the knuckle body are formed by a combination of sheet metal materials, which are advantageous in terms of weight. Furthermore, a knuckle structure for a driven wheel of a vehicle is characterized in that the rigidity for resisting deformation is improved by forming the bent portion of the sheet metal material, and the knuckle structure is provided to hold a support portion that supports the lower end portion of the shock absorber. Specifically, in a frame structure that supports a vehicle driven wheel, a main body part to which a wheel axle is fixed,
and a main body to which the lower end of the shock absorber is fixed between the inner shell, which is made of a bent flat metal sheet, and has a support part extending from the main body and serving as a support for the brake device, and the vehicle. , and an outer shell made of a bent flat metal sheet having a support part extending from the main body part and serving as a support part of the brake device, are connected to each other so that their peripheral edges have substantially the same shape and face each other. This is a sheet metal knuckle for a driven wheel of a vehicle, characterized in that the nut is provided so as to be attached to the vehicle, and is configured to form a hollow shell structure by fixing the peripheral edges thereof.
