Abstract

Abstract A door locking knob structure for a vehicle has a push-button provided on the side of a knob main body which faces the inside of the compartment of the vehicle in such a manner that the push-button is movable together with the knob main body. When pressed, the push-button is withdrawn into the knob main body so as to define a finger receiving recess which allows an occupant of the vehicle to apply his finger thereto and raise the knob main body. Accordingly, when the door is in a locked state, the push-button makes the finger receiving recess disappear, and there is no gap between the push-button and the knob main body. Thus, it is possible to prevent any accidental or undesirable unlocking of the door.
