<p><P>PROBLEM TO BE SOLVED: To provide gear units, in which a rear bearing of bearings between double axis first and second input shafts can be disposed to a rear end of an outer second input shaft to elongate a bearing span, and a counter shaft is tapered toward a front end. <P>SOLUTION: In arrangement of gear units G2, G4, G6 covering a first input shaft 5, gears 30, 34 out of gears 30, 32, 34 on a second input shaft 6 can provide a bearing housing space for a needle bearing 8, a lowest speed gear 34 for a fourth speed is disposed to a side farthest from an engine, a highest speed gear 30 for a sixth speed out of gears other than the lowest speed gear 34 for the fourth speed is disposed to a side nearest to the engine, and a gear for a second speed is disposed between both ends of the second input shaft 6. Since the housing space of the needle bearing 8 is secured between the rear end of the second input shaft 6 and the first input shaft 5, the span of the needle bearings 7, 8 can be elongated and the counter shaft 15 can be tapered toward the front end. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
