PURPOSE:To enable forcible supply of oil to be carried out onto the fitting faces between the peripheral grooves of shift gears and related fork-like catches by forming a main oil supply passage and oil distribution passages through a shift fork shaft and shift forks, respectively. CONSTITUTION:Pressurized lubricating oil from an oil pump P passes through a main oil supply passage 11 which is formed through a shift fork shaft 2, and is then supplied into oil distribution passages 151-153 which are drilled in shift forks 41-43, respectively. The oil distribution passages 151-153 are respectively communicated to notched grooves 171-173 whose openings are shifted to the sides where shift gears 71-73 fall into the fork-like catches 61-63 of the shift forks while turning. Lubricating oil is therefrom forcibly supplied onto the slidably engaged faces between the peripheral grooves of the shift gears and the fork-like catches. |
