Claims

[Scope of utility model registration request]

A shift block having a groove extending in a direction perpendicular to the shift rod and engaging with the end of the gear shift lever is provided at the ends of the plurality of shift rods arranged in parallel with each other, and the shift block is provided with a groove that extends in a direction perpendicular to the shift rod and engages with the end of the gear shift lever, and the gear shift is performed by selecting the gear shift lever. In a speed change operation mechanism of a gear transmission, in which an end of a lever is engaged with one of the shift blocks, and the shift rod is moved in the axial direction by a shift operation of the speed change lever, and a predetermined meshing of the speed change gears is achieved. , a pair of stop walls are provided on the wall of the case opposite to the end wall of the shift block provided on the shift rod for switching between a predetermined gear and a reverse gear, and the shift lever is disposed inside the pair of stop walls. A stop plate having an angular cross section is slidably and rotatably supported by a support shaft extending in the select operation direction, and the stop plate is connected to a vertical plate parallel to the end wall of the shift block and a groove of the shift block. the stop plate is biased by a spring so as to cover the upper half of the groove of the shift block and the half on the reverse gear side when the stop plate is in the neutral position, and the stop plate is biased by a spring so as to cover the upper half of the groove of the shift block and the half on the reverse gear side, and The stop plate is rotated against the spring when the shift lever is returned to the neutral position, and the stop plate is configured to come into contact with a stop wall of the case when the shift lever moves too far toward the reverse gear side. A speed change operation mechanism for a gear transmission characterized by the following.
