MIS-SHIFT PREVENTING DEVICE FOR TRANSMISSION

PURPOSE:To prevent the wear of a rotary sliding section and to surely prevent a mis-shift to a reverse drive gear by providing a blade part which receives a splashing lubricating oil to rotate a shift stopper and a lubricating oil splashing member to splash the lubricating oil to the blade part during advance running. CONSTITUTION:In the case where an output shaft 4 is rotating in a normal rotating direction F during advance running, a shift stopper 23 rotates in the normal rotating direction F of the output shaft 4 against energizing action caused by the weight of a blade part 26a serving as a counter weight section so as to rotate with the output shaft 4 because of rotational resistance being due to the viscosity of oil given between a boss 22 and the side face and annular part 24 of a gear through the film of the oil which is spattered by a reverse driven gear and received by a blade part 26a. Thus the tip of a stopper arm 25 abuts on a shift shaft 14 to control the movement to the right of a shift fork 15 for surely preventing a mis-shift to a reverse drive gear 6 during the advance running.
