Abstract
Abstract A vehicle door may sometime be positioned in a half-latched condition for bringing the door from this condition to a fully latched condition, a door closing device is actuated in such manner that a pawl is rotated by a motor so as to be fully engaged with a striker. Due to this rotation of the pawl, the door is also rotated towards the body. If a portion of material or other objects are unfortunately put between the body and the rotating the door, the transmission of the driving force from the motor to the pawl through a first member and a second member can be interrupted by actuating an inside-handle (an outside-handle) which is operatively connected to the first member. Thus, further movement of the door is prevented, thereby preventing further damage of the material or injury of the other objects.
