摘要： A shift lever support mechanism for a transmission comprises a shift lever having a partly spherical pivot body and a distal end extending from the partly spherical pivot body for engagement with a gear shifting actuator shaft of the transmission, a retainer member adapted to be mounted on the transmission casing and having a bore accommodating the spherical pivot body therein, the retainer member including a partly spherical seat supporting the partly spherical pivot body, the retainer member having a central opening through which the distal end extends, resilient means disposed in the bore in the retainer member for normally urging the partly spherical pivot body against the partly spherical seat, and a boot mounted on the shift lever and the retainer member and defining a space therein communicating with the bore in the retainer member. The retainer member has an escape passage defined in a wall thereof adjacent to the partly spherical seat for communication between the space and the interior of the transmission casing. With this arrangement, the space in the boot and the interior of the transmission casing are equally pressurized through the escape passage. No oil is filled in the boot space and will not leak out of an air vent in the boot.

摘要： 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.
