Abstract

A door locking apparatus for a vehicle including: a first locking/unlocking mechanism driven by a first driving mechanism operable by a knob inside a car and a control switch, and switchable between an unlocked state where operations of inside and outside handles respectively provided inside and outside the car are effective, and a locked state where the operation of the outside handle is ineffective while that of the inside handle being effective; a second locking/unlocking mechanism driven by a second driving mechanism operable by the control switch, and switchable between an unlocked state where the operation of the inside handle is effective, and a locked state where the operation thereof is ineffective; and a third locking/unlocking mechanism switchable between an unlocked state for enabling a transmission of an unlocking force from the knob to the first locking/unlocking mechanism, and a locked state for disabling the transmission thereof.
