<P>PROBLEM TO BE SOLVED: To maintain an axial position of a gear to a shaft member in a specified state, by applying a preload to a tapered roller bearing, without complicating assembling work. <P>SOLUTION: A collar member 40 is arranged between a transfer gear 21 and a differential input shaft 20. The collar member 40 allows a first end surface to abut on an end surface of the transfer gear 21 and allows a second end surface to abut on an inner end surface 22b1 of an inner race 22b to secure a clearance between the end surface of the transfer gear 21 and the inner end surface 22b1 of the inner race 22b. A holder 50 is held in a tip part of the differential input shaft 20 for regulating a maximum mutual distance d2 along the axial direction of two inner races 22b and 23b in a state of including the transfer gear 21 and the collar member 40 between an abutting end surface 20d and itself by abutting on an outer end surface 22b2 of the inner race 22b in the tapered roller bearing 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
