Abstract
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 …
