ABSTRACT:
In a joint structure for an axle, the outer race of a constant-velocity joint is formed at the end of an axle shaft disposed inside a hollow spherical portion of a tubular axle, a seal fitted to a knuckle is disposed in such a manner as to cross the axes of a pair of king-pins disposed in a vertical direction, the fitting position of the seal is substantially the largest diameter position of the hollow spherical portion of the tubular axle, the knuckle consists of a knuckle portion supported rotatably by the king-pin on the upper side and a knuckle portion supported rotatably by the king-pin on the lower side, and the seal is clamped between the knuckle portion on the upper side and the knuckle portion on the lower side. Accordingly, the annular seal is slidable substantially to the part of the hollow spherical portion with the swinging movement of the knuckle, which part is the connection of the hollow spherical portion with the end of the tubular axle, and a steering angle can thus be increased.
