Vehicle door opening/closing device
A front cable and a rear cable are wound about a drum, are made to change direction by being caught onto a front pulley and a rear pulley, respectively, disposed on a center rail, and are respectively connected to a guide roller unit at respective terminals. The closing cable section of the front cable is routed to the outside of the center rail, the corresponding terminal being connected to the guide roller unit farther rearward than a load roller, and the opening cable section of the rear cable is routed to inside the center rail, the corresponding terminal being connected to the guide roller unit.
1. A device for opening and closing a vehicle door comprising:
a guide rail configured to be arranged on a quarter panel at a rear side of a door opening formed in a side portion of a vehicle body, wherein the guide rail is configured to extend in a front-rear direction and includes an inclined portion on a front end, and the inclined portion is configured to be inclined toward a vehicle interior, wherein the guide rail possesses a cross-sectional shape that is open toward a vehicle exterior and the vehicle door when the guide rail is arranged on the quarter panel;
a guide roller member configured to be coupled to the vehicle door that opens and closes the door opening, wherein the guide roller member includes a roller that can roll on the guide rail;
a drive member configured to be fixed to the vehicle body, wherein the drive member includes a drive source and a drum that is rotated and driven by the drive source;
a front pulley and a rear pulley located at a front side and a rear side of the guide rail;
a cable wound around the drum and running along the front pulley and the rear pulley to change directions, wherein the cable includes two ends that are each coupled to the guide roller member;
wherein the front pulley is located above or below the guide rail;
wherein a closing operation cable portion, which is a portion of the cable extending from the front pulley to the guide roller member, is located above or below the guide rail, and a corresponding one of the ends is coupled to the guide roller member at a rear of the roller; and
wherein an opening operation cable portion, which is a portion of the cable extending from the rear pulley to the guide roller member, is located in the guide rail, and a corresponding other one of the ends is coupled to the guide roller member.
2. The device according to claim 1 , wherein the end of the closing operation cable portion is located proximate to the end of the opening operation cable portion as viewed from above.
3. The device according to claim 1 , wherein
the end of at least one of the closing operation cable portion and the opening operation cable portion is coupled to the guide roller member from a direction that differs from a direction in which the cable extends to the end of the at least one of the closing operation cable portion and the opening operation cable portion.
4. The device according to claim 3 , wherein the end of the at least one of the closing operation cable portion and the opening operation cable portion includes:
a holder open toward the vehicle interior; and
a separation stopper fitted into the holder, wherein a coupling portion of the guide roller member to which the end is coupled is inserted and fitted into the separation stopper.
5. The device according to claim 1 , wherein
the guide roller member includes two guide rollers arranged in the front-rear direction on opposite sides of the roller, wherein the guide rollers can roll on the guide rail and rotate about axes extending in a vertical direction of the vehicle; and
the end of the opening operation cable portion is coupled to a coupling portion of the guide roller member, wherein the coupling portion is arranged coaxially with the rear guide roller.
