<p>PURPOSE:To enable the wear of members to be avoided by maintaining a clutch body in such a state as it is apart from a stopper part through supply pressure oil so as to avoid the sliding of a stopper part. CONSTITUTION:The transmission gear is so constituted that the distance D between the wall surface 40 of a transmission case and that 39 of a clutch body is approximately 2mm, and that a stopper part 27 is kept apart from a clutch body part 21b. In the condition in which a clutch is connected in, the clutch body 21 is pressedly pushed toward a clutch hub 25 through the oil pressure acting on the wall surface 39 of the clutch body in an oil chamber 35, and the stopper part 27 is maintained in such a state that the clutch body part 21b is kept apart from it. Accordingly, the oil chamber purposed for connecting oil passages is utilized for the pressure oil chamber purposed for separating operation, and the sliding of the stopper part can be avoided, thus the wear of members can be sufficiently avoided.</p> |
