PURPOSE:To obtain the smooth lubrication by introducing lubricating oil to a bearing of a drive pinion shaft via an oil receiver fixed on the backside of a partition wall and further to a shaft-support part of a speed-change gear on a counter shaft. CONSTITUTION:In the back of a partition 21a, a lubricating-oil introduction device 60 is provided to guide lubricating oil to a top bearing Bg of a counter shaft 33, the fifth speed gear 33h, a synchronizer 33e, and both bearings 43 and 44 of a drive pinion shaft 41. The introduction device 60 consists of an oil receiver 62 fixed on the backside of the partition wall 21a and a connection passage 66 connected into this oil receiver 62. Meanwhile, this connection passage 66 consists of a hole 65 axially provided on the partition wall 21a at the outer end, a side hole 63 opened to a boss part inner hole 67 and a hollow space 53 between both bearings 43 and 44 on the inner end, and an axial oil hole 68a and a radial oil hole 68b of the counter shaft 33. |
