DOOR OPENING AND CLOSING DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To enhance the layout performance of the door opening and closing device for vehicle by simplifying the layout structure of power supply lines.

SOLUTION: A front door 13 is slidingly opened and closed by a slide mechanism and a parallel link mechanism. The load of the front door 13 is supported by connecting between a vehicle body 12 and the front door 13 a load support arm 61 provided with a body side supporting piece 62 and a door side supporting piece 63 which are connected to each other by a connecting shaft 66. An electric motor 52 causing the front door 13 to be opened and closed by driving the slide mechanism and the parallel link mechanism is disposed inside the front door 13. A power supply line 72 for connecting the electric motor 52 and a battery 71 mounted on the vehicle body 12 is disposed along the load support arm 61. A middle part of the power supply line 71 is disposed windingly on the connecting shaft 66 from the open direction side so as to absorb an excess length change of the power supply line 72 due to bending of the load support arm 61.
