Abstract

PURPOSE: To prevent misworking in the speed change, such as a reverse change against the instruction, by preventing a shifter from shifting, during the operation of speed change gears, by a thrust-plate-related operation.
CONSTITUTION: A thrust plate 12 is provided with a notch 12a, and, during the motion of a gear 19, the thrust plate 12 rotates rightward until a pin 38 hits a stopper 37. Since the notch is spart from a gear 13, the gear 13 cannot move over to the gear 19, even if so attempted by using the shifter 10, because the gear tooth part of the gear 13 is stopped by thrust plate 12. If the gear 19 stops to rotate, the thrust plate 12 returns to such a position, owing to a spring 16, as to bring the notch 12a to the gear-tooth-tip position of the gear 13, due to the positional relation between a pin 39 and the stopper 37, which permits the gear 13 to pass through the thrust plate 12 to gear into the gear 19.
