Parking device for automatic transmission

摘要

A parking device for an automatic transmission wherein a parking gear provided in a transmission for the automatic transmission comprising the transmission disposed at a rear stage of a torque converter is locked at the time of parking; characterized by that a leaf spring, which urges a locking arm apart from a parking gear when a driving mode is selected to a range other than P-range, is provided on a push rod moving the locking arm which locks the parking gear toward the parking gear; a pin serving as a fulcrum of the leaf spring is held to a housing of the transmission at a position where a spring force of said leaf spring functions so as to part the locking arm from the parking gear when the driving mode is selected to a range other than P-range; and the leaf spring is formed into such a shape that the leaf spring does not contact with the pin as the driving mode is shifted from R-range to P-range.
