DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 3 is a schematic diagram showing the vehicle door opening and closing device according to the present embodiment. As shown in the figure, the vehicle body 10 is provided with an upper rail 11 and a lower rail 12 along an upper edge and a lower edge of a door opening 10a formed on a side portion thereof, and a rear quarter of the door opening 10a. A center rail 13 extending in the front-rear direction in the panel 10b is installed. A slide door 20 as a vehicle door is supported on the upper rail 11, the lower rail 12 and the center rail 13 via a guide roller unit 14 so as to be movable in the front-rear direction. The sliding door 20 opens and closes the door opening 10a as it moves in the front-rear direction. In addition, the cable guide 15 is installed in the quarter panel 10b along the lower edge of the center rail 13 over the full length.

  As shown in an enlarged view in FIG. 1, the door inner panel 16 as a door panel constituting the door inner plate of the slide door 20 has a door thickness direction (perpendicular to the paper surface) at the middle portion in the vehicle height direction at the rear end portion. A raised portion 17 that is raised on the front side) is formed. The raised portion 17 has a belt-like top portion 17a and inclined portions 17b and 17c formed before and after the top portion 17a, and is formed in a mountain shape. A door side unit 40 is attached to the door inner panel 16 on the front side of the raised portion 17. The door unit 40 is made of, for example, a metal plate and includes a bracket 41 that extends substantially in the vehicle height direction. The bracket 41 is fixed to the door inner panel 16 by fastening with, for example, bolts and nuts, and forms an inclined portion 41a bent along the raised portion 17 (inclined portion 17b) at the upper rear end portion thereof.

  The upper end portion of the drive member 21 is fixed to the lower end portion of the bracket 41 by fastening with, for example, a bolt and a nut. The drive member 21 includes a drive motor 22 and a drum 23 that is disposed on the output shaft of the drive motor 22 and is rotationally driven by the drive motor 22. A first cable 24 and a second cable 24 are connected to the drum 23 as cables. A cable 25 is wound. That is, the first and second cables 24 and 25 are wound around the drum 23 in a state in which one end is locked to the drum 23. The first and second cables 24 and 25 are selectively wound and fed out by the drive member 21. Further, the sub bracket 46 is fixed to the lower end portion of the driving member 21 by fastening with, for example, a bolt and a nut. The lower end portion of the drive member 21 is fixed to the door inner panel 16 through the sub bracket 46. Thereby, the relatively heavy driving member 21 can be more stably fixed to the door inner panel 16. The thickness of the sub bracket 46 is set to be thicker than the thickness of the bracket 41.

  On the other hand, a relay pulley 50 is attached to the upper end of the bracket 41 near the drive member 21 on the front side of the inclined portion 41a. That is, the relay pulley 50 includes a base plate 51 that is formed in a substantially dish shape, for example, using a metal plate and is fixed to the bracket 41 by fastening with bolts and nuts. As shown in the sectional view along the line AA of FIG. 1 in FIG. 2, a substantially cylindrical rotating shaft 52 extending in the orthogonal direction (that is, the vehicle width direction) is inserted into the base plate 51 together with the bracket 41. ing. A first pulley 53 and a second pulley 54 that are arranged side by side in the axial direction (that is, the vehicle width direction) are rotatably supported on the rotating shaft 52. The first and second pulleys 53 and 54 are allowed to rotate relative to each other while being overlapped in the axial direction of the rotary shaft 52, and the outer diameters of the first and second pulleys 53 and 54 are set to be equal to each other. Note that one end portion of the rotating shaft 52 that passes through the bracket 41 has a locking flange 52a that is enlarged in a substantially pan shape, and the other end portion that passes through the first pulley 53 is caulked. It has a substantially truncated cone-shaped enlarged diameter portion 52b that is crushed. Accordingly, the first and second pulleys 53 and 54 are held and supported by the rotating shaft 52 in a manner that the first and second pulleys 53 and 54 are sandwiched between the locking flange 52a (base plate 51) and the enlarged diameter portion 52b.

  The first cable 53 wound and fed from the drum 23 is hung on the first pulley 53 disposed on the side far from the base plate 51 (bracket 41) in such a manner that it is guided. Further, the second cable 54 wound and fed from the drum 23 is hung on the second pulley 54 disposed on the side close to the base plate 51 (bracket 41) in a manner to guide the second cable. The first and second cables 24 and 25 are both hung from the front side of the first and second pulleys 53 and 54 in the illustrated clockwise direction, and between the drum 23 and the first and second pulleys 53 and 54. The rotary shaft 52 is arranged so as to form a substantially inverted V shape when viewed in the axial direction. The first and second cables 24 and 25 are passed from the slide door 20 side to the vehicle body 10 side.

  That is, as shown in FIG. 2, the raised portion 17 has insertion holes 17d and 17e formed in the inclined portions 17b and 17c so as to face each other in the front-rear direction. And the cylindrical cable penetration member 44 which penetrates the protruding part 17 is attached to the protruding part 17 in the aspect which connects between these insertion holes 17d and 17e in the front-back direction. On the other hand, the inclined portion 41 a of the bracket 41 is formed with a through hole 41 b that opens in the front-rear direction so as to face the opening facing the insertion hole 17 d of the cable insertion member 44. A bottomed cylindrical seal member 45 made of, for example, a rubber material is inserted and mounted in the through hole 41b (opening portion of the cable insertion member 44) in such a manner as to close the through hole 41b. Accordingly, the space on the front side of the inclined portion 41a of the bracket 41 (that is, the arrangement space of the first and second pulleys 53 and 54) passes through the through hole 41b, the cable insertion member 44 to which the seal member 45 is attached, and the like. It communicates with the outside of the sliding door 20, that is, the vehicle body 10 side. The first and second cables 24 and 25 hung on the first and second pulleys 53 and 54 are guided to the outside of the slide door 20 through the through holes 41b and the cable insertion member 44. At this time, the first and second cables 24 and 25 penetrate the seal member 45 in a liquid-tight manner, thereby preventing water from entering the arrangement space side (the bracket 41 side) of the first and second pulleys 53 and 54. Has been.

  As shown in FIG. 3, the first and second cables 24 and 25 guided to the outside of the slide door 20 are guided pulleys connected to a guide roller unit 14 that moves on the center rail 13 on the rear side of the raised portion 17. 27 is passed from the slide door 20 side to the vehicle body 10 side and routed along the cable guide 15 in the front-rear direction. The first cable 24 is guided by the cable guide 15 and routed to the front side, and is connected to the vehicle body 10 side on the front end side of the cable guide 15 via a tensioner 28 connected to the other terminal. They are connected by fastening with nuts. Further, the second cable 25 is guided by the cable guide 15 and routed to the rear side, and via the tensioner 29 connected to the other terminal, on the vehicle body 10 side on the rear end side of the cable guide 15, for example, They are connected by fastening with bolts and nuts. Accordingly, the door side unit 40 (first and second pulleys 53, 54, etc.) is arranged based on the vehicle height position of the center rail 13.

  In such a configuration, for example, when the second cable 25 is wound up while the first cable 24 is fed out by the driving member 21, the slide door 20 moves rearward to open the door opening 10a. On the other hand, when the second cable 25 is fed out while winding the first cable 24 by the driving member 21, the slide door 20 moves forward to close the door opening 10a.

  As shown in FIG. 4, a cover member 57 made of, for example, a resin material is attached to the bracket 41 assembled with the drum 23 and the first and second pulleys 53 and 54. The cover member 57 includes a substantially covered cylindrical drum cover portion 57a that rotatably accommodates the drum 23, and a substantially covered cylindrical pulley cover portion 57b that rotatably accommodates the first and second pulleys 53 and 54. A substantially U-shaped groove-shaped first cable cover portion 57c that accommodates the first cable 24 between the drum 23 and the first pulley 53, and a substantially U-shape that accommodates the second cable 25 between the drum 23 and the second pulley 54. A groove-shaped second cable cover portion 57d is integrally provided. The drum cover portion 57a, the pulley cover portion 57b, and the first and second cable cover portions 57c and 57d communicate with each other so as not to interfere with the arranged first and second cables 24 and 25. The cover member 57 has an attachment piece 57e extending to the outer peripheral side that is separated from the pulley cover portion 57b of the drum cover portion 57a, and from the first and second cable cover portions 57c and 57d in the vicinity of the drum cover portion 57a. There are mounting pieces 57f and 57g extending to the opposite sides.

  The cover member 57 superimposed on the bracket 41 or the like is fastened to the drive member 21 at the mounting piece 57e, for example, by screws, fastened to the bracket 41 at the mounting pieces 57f and 57g, and the rotating shaft 52 at the center of the pulley cover portion 57b. It is fixed by being fastened to. The drum 23, the first and second pulleys 53 and 54, and the first and second cables 24 and 25 spanned between the drum 23 and the first and second pulleys 53 and 54 are attached to the bracket 41. Since the whole is covered by the cover member 57 to be worn, the unity of these is increased. Further, the cover member 57 covers the outer peripheral sides of the first and second pulleys 53 and 54 in the pulley cover portion 57b, so that the first and second cables 24 hung on the first and second pulleys 53 and 54 are covered. , 25 and the like, and the first and second cables 24, 25 are routed in the first and second cable cover portions 57c, 57d, thereby suppressing each lateral shake and the like.
