<p>The present invention relates to a door hinge device of a vehicle and, more specifically, to a door hinge device of a vehicle capable of reducing a closing speed by generating a rotational resistance only when doors or trunks are firmly closed at a speed greater than a constant speed. The present invention provides the door hinge device of the vehicle comprising a door bracket connected to the door and connected to one side of the bracket of the vehicle to be rotated; a pawl lever assembled to the door bracket to be axis-rotated and rotated when the door is closed at a speed greater than a constant speed; a rotation resistance ring assembled to the bracket of the vehicle to be axis-rotated and connected to be interlocked with the pawl lever when the door is closed at a speed greater than a constant speed; a friction material assembled inside the rotation resistance ring to generate rotation resistance when the rotation resistance ring is axis-rotated.</p> |
