Description

  The present invention relates to a vehicle door opening / closing device for driving a vehicle door related to opening / closing of a door opening formed in a vehicle body, and a method for manufacturing the same.

  Conventionally, as a vehicle door opening and closing device, for example, the one described in Patent Document 1 is known. This vehicle door opening and closing device includes a drive member (14) fixed to the vehicle body side. The drive member includes a drive source (17), a drum (19) that is rotationally driven by the drive source via a speed reduction mechanism (18), and cables (20, 21) wound around the drum. Both ends of the cable are connected to the vehicle door side, and the vehicle door is opened and closed by selectively winding and unwinding the cable by the driving member.

  Patent Document 1 also proposes to provide a tensioner at the end of the cable. This tensioner is provided with a biasing member such as a spring in a tensioner case fixed to the vehicle body side (base plate) to apply tension to the cable. Thereby, for example, the tension of the cable is appropriately maintained, and the vehicle door is smoothly opened and closed.

  However, since the tensioner of such a vehicle door opening and closing device has a long shape in the direction of pulling the cable, the tensioner is arranged so that the tensioning direction of the tensioner coincides with the vehicle longitudinal direction (cable extending direction). Then, there exists a possibility that a vehicle may enlarge in the front-back direction. Therefore, a terminal disposed on the vehicle rear side of the cable is bent at, for example, a substantially right angle with respect to the vehicle front-rear direction, and a tensioner is provided at the terminal, and the tension direction of the terminal is substantially orthogonal to the vehicle front-rear direction. A configuration in which tensioners are arranged is conceivable. According to such a configuration, the vehicle can be reduced in size in the front-rear direction compared to a configuration in which the tensioner on the vehicle rear side is arranged so that the tensioning direction of the tensioner matches the vehicle front-rear direction.

Thereafter, the tension recesses 43 of the tensioner bracket 41 are rotatably locked to the coupling shaft 34 of the mounting member 31 and, as shown in FIG. Is derived from the center rail 13 (the connecting step). That is, at this time, the tensioner bracket 41 is in a state in which the longitudinal direction (the direction in which the coupling recess 43 and the screw hole 44 are arranged) is substantially parallel to the vehicle longitudinal direction. At this time, the tensioner bracket 41 is prevented from being detached from the connecting shaft 34 by the flange portion 34 a of the connecting shaft 34.

  Next, the tensioner bracket 41 is rotated around the connecting shaft 34 of the mounting member 31 so as to go around the rail mounting groove 3b toward the vehicle rear side, thereby applying a desired tension to the second cable 25. In this state, the tensioner 29 is disposed at the vehicle rear side portion in the rail mounting groove 3b (turning step).

On the other hand, the tensioner bracket 41 is formed with a locking piece 52 extending from the inner end in the vehicle width direction through the lower side of the locking projection 51 to the front side of the vehicle. The part is formed with a projecting part 52a projecting outward in the vehicle width direction. The protruding portion 52 a of the locking piece 52 is configured to be able to be locked in the reverse rotation direction of the tensioner bracket 41 with respect to the inner wall portion 33 a of the mounting member 31. Further, the locking piece 52 is configured to be locked in the vertical direction (the axial direction of the connecting shaft 34) with respect to the locking projection 51. Even with such a configuration, it is possible to obtain substantially the same operational effects as in the above embodiment.

  Further, a locking projection as a locking portion protruding upward is provided in the tensioner bracket 41, and a locking hole through which the locking projection is inserted is provided in the extension portion 33 of the mounting member 31, and the connection shaft 34 is centered. It is good also as a structure latched in the rotation direction. The concave-convex relationship between the locking projection and the locking hole may be reversed.

  In the above-described embodiment, the rotational connection structure between the tensioner bracket 41 and the attachment member 31 is a structure that can be easily attached and detached by the connection recess 43 and the connection shaft 34. However, for example, the tensioner bracket 41 is attached to the attachment member 31. It is good also as a structure which carries out rotation connection so that attachment or detachment is impossible.

  In the above embodiment, the rotation shaft (connection shaft 34) of the tensioner bracket 41 is configured to be parallel to the vertical direction. However, the present invention is not particularly limited thereto, and is inclined with respect to the vertical direction. May be set.

  In the above-described embodiment, the tensioner bracket 41 is fastened and fixed to the mounting member 31 with the bolt 48. However, for example, a configuration in which the tensioner bracket 41 is fastened and fixed with a caulking pin may be used.

  In the above embodiment, the attachment member 31 on the vehicle body 1 side is provided on the center rail 13, but is not particularly limited thereto, and may be formed integrally with the body panel 1 a, for example. That is, the tensioner bracket 41 may be directly attached to the body panel 1a.

  In the above embodiment, the bending direction of the terminal on the vehicle rear side of the second cable 25 is configured to be substantially parallel to the vehicle width direction. That is, the tensioner 29 is arranged on the vehicle rear side and the pulling direction thereof is substantially parallel to the vehicle width direction, but is not particularly limited thereto. For example, the bending direction of the terminal on the vehicle rear side of the second cable 25 is made parallel to the vertical direction, and the tensioner 29 is arranged on the side surface in the vehicle width direction so that the tensioning direction of the tensioner 29 is parallel to the vertical direction. May be.
