Abstract
A shift mechanism for a change-speed gear transmission includes a manual gearshift lever arranged to be selectively shiftable toward forward speed-ratio and reverse-ratio positions at the same gate in a gearshift pattern, a movable member integral with a selector shaft mounted within a housing assembly of the gear transmission for both axial and rotary movement and being operatively connected to the gearshift lever to be axially moved in selecting operation of the gearshift lever toward the gate and to be rotated in shifting operation of the gearshift lever toward one of the forward speed-ratio and reverse-ratio positions. The movable member is provided with a radial lever arm arranged to be selectively movable for engagement of the forward and reverse gear ratios and provided with a radial projection which is arranged to be engaged with a recessed portion formed on one end of a spring-loaded restrict pin in shifting operation of the gearshift lever from the forward speed-ratio position toward the reverse-ratio position across the same gate to prevent an error in the shifting operation.
