PURPOSE:To lubricate a sliding part sufficiently, by inclining the end of the tip part of a shift fork, and leading oil falling in drops from the upper part, to the slide part to a coupling sleeve. CONSTITUTION:An upper end 5a of a shift fork SF5 provided with a fork shaft 6 on its lower part is inclined. That is to say, the upper end 5a is inclined so as to go down toward the inside of the SF5 at an angle alpha against a horizontal line L passing through the center point ''0'' of a coupling sleeve CS4 fitted into the SF5. Therefore, oil 7 falling in drops from the upper part is led as indicated with an arrow B to the sliding part of a tip 5b of the SF5 and the CS4. As for a tip 5c of the other side of SF5, even if it is conventional type, there is no problem for lubrication because its upper end 5d is inclined so as to go down toward the inside from the first. |
