PURPOSE: To facilitate gear shift operation through remarkable reduction of wear of the tooth part of a clutch gear by the sufficient feed of oil not only to a coupling sleeve but also to a clutch gear through the spline part of a synchro-hub. CONSTITUTION: In a manual transmission having a synchronous mechanism comprising a coupling sleeve 6 slidably fitted in externally of the spline part of a synchro-hub 14 fitted in the spline part of a shaft 2; and a clutch gear 9 fitted in and externally of the boss part of a gear 8 rotatably fitted in and externally of the shaft 2 and disengageably linked to a coupling sleeve 6, the lubrication structure of the manual transmission is constituted in such a manner that a feed oil receiving part 16 approximately in a cylindrical shape is arranged at the side, on the feed oil side of a spline part 15, of the synchro-hub 14. |
