A door lock apparatus for a vehicle includes a latch mechanism engaged with and released from a striker, a first lever rotatably driven by a driving unit from a predetermined first initial position, a second lever operatively connected to the first lever and rotated from a predetermined second initial position and switching a state of the latch mechanism relative to the striker, a biasing member biasing the second lever to be returned to the second initial position, and an engagement portion provided at the first lever and releasing the second lever by thrusting the second lever in accordance with the rotational movement of the first lever returning to the first initial position from a constrained state where the second lever is constrained not to be returned to the second initial position after the second lever has changed the states of the latch mechanism.

Door lock apparatus for vehicle

The essential feature of the invention includes that both ends of a single torsion spring are elongated to form both arms which are engaged with a swinging lever actuated by the select operation and a fixed lever in such a manner that select return force at high and low gear position in select operation is equalized. Further feature of the invention is that a select return spring is provided at an area defined independently from the select shaft and a bell crank shaft.

Select return mechanism for a transmission

A parking brake foot pedal is pivoted to a bracket, and is formed with a ratchet plate portion. A pawl is engaged with the ratchet so as to hold the parking brake in the applied condition. A release lever is pivoted to the bracket so that it displaces the pawl away from the ratchet when it is pulled by a release structure. A resin bush is attached to the release lever at a position remote from its pivoting point. The bush has a hole through it which is narrowest at its middle portion and opens out towards its ends. A release cable passes through this hole in the bush, and on its end there is fixed a stop member larger than the internal diameter of the hole in the bush. Thereby, the end of the release cable is flexibly coupled to the release lever, so as not to be subject to severe bending stress when the release cable is pulled and rotates the release lever so as to displace the pawl away from the ratchet and release the application of the parking brake.
