PURPOSE:To enable an oil supply port to be easily formed, by extending the opening of a boss part, which supports in its one end a shift fork control shaft, to be protruded outside a case and mounting a supply oil plug to the point end of said opening while connecting the boss part with inside the case through a passage. CONSTITUTION:A transmission case 3A holds a control shaft 8, moving a shift fork 13, to be supported by boss parts 14, 15. The boss part 15 in one end side provides its opening to be protrusively extended to an outer side of the case, and a supply oil plug 16 is mounted to said opening. The boss part 15 forms in its internal end in a case side a passage R connecting the inside of the boss part 15 with inside the case. The case, forming the boss part serving also for an oil supply port, enables the oil supply port to be cheaply further easily formed. |
