PROBLEM TO BE SOLVED: To effectively supply lubricating oil scraped up by a gear within a transmission case into a control box.SOLUTION: A lubrication structure of a transmission is provided that comprises: a transmission case 10 into which lubricating oil is encapsulated; a shaft 12 rotatably journaled by the transmission case 10; a gear 15 provided in the shaft 12 and scraping up lubricating oil by rotation; a control box 20 provided above the transmission case 10; an oil introduction port 10B formed to penetrate an upper wall part 10A of the transmission case 10, partitioning the transmission case 10 and the control box 20; and a shift block 31 disposed within the transmission case 10 located below the oil introduction port 10B. In the select-direction side part of the shift block 31, an inclined plane part 10C is provided which is formed by cutting the select-direction side part obliquely upward.SELECTED DRAWING: Figure 2 【課題】変速機ケース内のギヤにより掻き上げられた潤滑油をコントロールボックス内に効果的に供給する。【解決手段】潤滑油が封入された変速機ケース１０と、変速機ケース１０に回転可能に軸支されたシャフト１２と、シャフト１２に設けられて回転により潤滑油を掻き上げるギヤ１５と、変速機ケース１０の上部に設けられたコントロールボックス２０と、変速機ケース１０とコントロールボックス２０とを仕切る変速機ケース１０の上壁部１０Ａに貫通形成された油導入口１０Ｂと、油導入口１０Ｂの下方に位置する変速機ケース１０内に配置されたシフトブロック３１とを備え、シフトブロック３１のセレクト方向の側部に、その側面を上面に向かって斜めに切か欠いて形成した傾斜面部１０Ｃが設けられた。【選択図】図２
