<P>PROBLEM TO BE SOLVED: To provide a door opening/closing device for a rear door constituted to change the door immediately into door opening operation when the rotation of a motor is reversed into a door opening direction from a door closing direction in a self-closing region of the door. <P>SOLUTION: A door frame is provided with a pressure sensitive detecting means for detecting load caused by contacting an obstacle. With the rotation of a driving gear 4 into the door closing direction from its initial position, a ratchet mechanism is moved into an engagement allowed position from its initial position by a moving member (a plate spring 19), and when a pressure sensor detects load in a state of performing door closing operation by a closure assisting means, the driving gear 4 is rotated in the door opening direction according to a detection signal of the pressure sensor to rotate an opener operating lever 6 in the door opening direction through the ratchet mechanism (a ratchet 12, and engaging lever 13 and a claw 15) engaged with the driving gear 4, thus operating an opener 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
