Abstract: A device for selectively placing an automobile's parking brake in its operative and inoperative positions, including (a) a pivotable lever connected to the brake via a cable; (b) a stationary sector having a plurality of teeth; (c) a pawl pivotably supported by the lever and engageable at its first arm with the sector's teeth; (d) a knob fitted over its axial part in a longitudinal hole formed in a lever's free-end portion, the knob being retractable inward upon pushing thereof; (e) a release rod connected at its first end to a pawl's second arm and including a head fitted in a recess formed in the knob's part; (f) a first spring permitting the pawl to be pivoted in a direction in which to cause its first arm to be engaged with the sector; and (g) a second spring fitted in the knob's recess to bias the rod's head to be engaged with a stopper provided in the recess.
