Abstract
A gear shifting apparatus for a multi-speed transmission includes: a shifting unit controlling gear shifting by an actuator, and a parking unit controlling parking by the actuator. In particular, the actuator includes a control motor driving a driven gear through a drive gear externally gear-meshed with the driven gear, and the shifting and parking units are operated by a force received from a cam block fixed to the driven gear. The shifting unit includes a fork slider slidably mounted on a fork rail, a shift fork integrally formed with the fork slider, and a cam contact pin integrally formed with the fork slider and contacting the cam block.
