Reverse gear mechanism for a vehicle transmission

摘要

A positioning means for a reverse shifting fork (50) includes a toggle spring for biasing the reverse shifting fork toward one of a reverse position shown by a solid line and a neutral position shown by a dashed line with a dead point set as a boundary between the reverse position and the neutral position, and a stopper pin (92) for stopping the reverse shifting fork in the reverse position and the neutral position against a biasing force of the toggle spring. The toggle spring is a torsional coil spring (91) and is compressed so that a biasing force is generated in a direction to move opposite ends of the spring connected respectively to the reverse shifting fork holder (85) and the reverse shifting fork away from each other, and the distance between the opposite ends is smallest in the dead point (100).
