PROBLEM TO BE SOLVED: To reduce a storage level of oil at a vertical set manual transmission while assuring a supply amount of oil supplied to a lubrication requiring part within a case of the transmission.SOLUTION: A lubrication structure of a transmission 1 comprising a gear row G2 comprised of a first gear 13 arranged at an input shaft 10 and a second gear 23 arranged at a counter shaft 30 and engaged with the first gear 13 and an oil supply member 65 for supplying oil scraped up by the second gear 23 to a lubrication requiring part within a transmission case 5 is constructed in such a way that each of the first gear 13 and the second gear 23 is provided with teeth having a prescribed twisting angle in respect to an axial direction and there is provided a guide member 60 having a wall surface with an outer diameter exceeding the teeth part while being adjacent to side positioned at a rear side in a rotating direction of the teeth in the axial direction of the first gear 13.SELECTED DRAWING: Figure 1 【課題】縦置き式の手動変速機において、変速機ケース内の要潤滑部に供給するオイル供給量を確保しつつオイルの貯留レベルを低減させる。【解決手段】入力軸１０に設けられた第１ギヤ１３とカウンタ軸３０に設けられて第１ギヤ１３に噛み合う第２ギヤ２３とでなるギヤ列Ｇ２と、第２ギヤ２３によって掻き揚げられたオイルを変速機ケース５内の要潤滑部に供給する給油部材６５とを備えた変速機１の潤滑構造において、第１ギヤ１３及び第２ギヤ２３はそれぞれ、軸方向に対して所定の捩れ角を有する歯部を備え、第１ギヤ１３の軸方向における歯部の回転方向後側に位置する側に隣接して、歯部を超える外径を有する壁面を備えたガイド部材６０が設けられる。【選択図】図１
