Abstract: In mounting an outer shell, welding is not required, and processing and locating of mounting holes are facilitated without lowering the fatigue and strength of the outer shell. A knuckle bracket comprising a bracket body A1, A2, A3, A4, A5, A6 on which an outer shell is mounted, a pair of parallel holding portions 10, 20, 21, 32 for mounting a knuckle arm extended laterally from the bracket body, and opposed mounting holes 12, 13, 29, 30, 34 formed in each of the holding portions, characterized in that a press-fit hole for press-fitting a lower portion of the outer shell is formed in an upper end of the bracket body.
