Abstract

PURPOSE:To surely prevent seizure of a transmission for a full-time 4WD vehicle by fitting the boss part of a gear mount casing onto an axle shaft coupled to a differential gear unit stored in the gear mount casing. CONSTITUTION:A differential gear unit 3 is disposed in a gear mount casing 6 to which an input gear 1 is fixed, and the boss section 6a of the gear mount casing 6 is fitted coaxially to one axle shaft 7l coupled to one element 3a in the differential gear unit 3. The inner surface 6' of a hole 6a' formed in the boss section 6a and facing the axle shaft 7l is subjected to surface treatment 50 by a nitriding process, a chromium plating process or the like so as to prevent seizure. With this arrangement, it is possible to prevent seizure between the axle shaft and the inner surface of the hole in the boss section of the gear mount casing.
