Claims

[Claims for Utility Model Registration] A sealing device for an axle shaft joint in which a boss part is spline-fitted to a differential output shaft and positioned via a spring pin, the boss part and a differential shaft being positioned via a spring pin. A labyrinth seal is formed between the shaft and the differential carrier around the shaft output shaft, and the spring pin is a solid columnar joint with an elastic body filled inside including the slit portion. sealing device.
