<p>A pivot lever connecting a parking rod and a hydraulic piston apparatus to each other is structured to be pivotable about a pivot shaft. The pivot shaft is fittingly inserted through a parking lock spring for biasing the parking rod to a parking pole side. The parking lock spring has a first end engaged with the pivot lever, and a second end fixed to a collar portion of a transmission case. A pivoting force of the pivot lever is applied to the first end of the parking lock spring, and a reaction force from the transmission case is applied to the second end thereof. Both ends of the parking lock spring are oriented so that the pivoting force of the pivot lever and the reaction force act in opposite directions to each other in a plane perpendicular to the pivot shaft.</p>
