ABSTRACT:
A parking apparatus of a continuously variable transmission includes a manual shaft vertically provided at the front of a primary shaft for driving both parking mechanism and manual valve operating mechanism. The parking mechanism comprises a lock arm, a parking rod, a parking pawl and a parking gear provided in a secondary pulley. The parking rod is rigidly fitted to a spacer and also it is slidably fitted to a cam. The cam abuts against the spacer by the biasing force of a spring. When a select lever is not positioned at a parking range, the spacer slides on a supporter so as to disengage the parking pawl with the parking gear. When the select lever is positioned at the parking range, the cam pushes upward the parking pawl so as to engage the parking pawl with the parking gear.
