[0036] Before the fork arm structure 100 with adjustable tire camber angle provided by the utility model is installed on the vehicle body, the first fork arm 2 is first rotated relative to the mounting seat 1 to adjust the angle between the first fork arm 2 and the mounting seat 1 to a preset value, and then the adjustment portion 21 provided on the first fork arm 2 cooperates with the mounting portion 13 provided on the mounting seat 1 to limit the rotation of the first fork arm 2 relative to the mounting seat 1, so that the angle between the first fork arm 2 and the mounting seat 1 is fixed to the preset value. In this way, the influence of the precision of the parts and the assembly clearance can be avoided, and the wheel camber angle is ensured to be within the optimal range, and the structure is simple and the cost is relatively low.

[0037] For further information, see Figures 2 to 6 The mounting portion 13 is a mounting screw hole 13a provided on the mounting seat 1, and the adjusting portion 21 is an adjusting slot 21a provided on the first fork arm 2. The adjusting slot 21a is extended along the rotation direction of the first fork arm 2 and corresponds to the mounting screw hole 13a. The fork arm also includes a fixing bolt 4 and a locking nut 5. One end of the fixing bolt 4 can be passed through the adjusting slot 21a and screwed into the mounting screw hole 13a.
