And, for each transom 27,28, with two transoms 27,28 make and have: volume is hung the drive side connecting portion 27a that extends along belt 26 of transmission component, 28a, be located at the reveal connecting portion 27b of its evolution forward end foot section, the shape of 28b, and because drive side connecting portion 27a, the door evolution of 28a is fixed in part in the way of aforementioned belt 26 to the end of rear side, so compare with the device in the past of the configuration of for the interference of the middle interconnecting piece 113 of avoiding transom 110A and gear motor 120 both above-below direction positions being staggered as shown in Figure 8, can will install height dimension on one side and suppress less, Yi Bian guarantee the stroke that slides of a body fully.

Further, among this embodiment, the door that the reveal connecting portion 27b of the 1st transom 27 is configured to be at any time electro-motor 22 opens and closes the position in the outside (right side among Fig. 1) of direction, and because reveal connecting portion 27b can be by the front side of electro-motor 22, so not need for fear of both interference and reveal connecting portion 27b is expanded towards the front side, the depth dimensions of the device of this part can further be cut down.

For example, the 2nd embodiment is shown in Fig. 6 and Fig. 7, in the door closing state, open and close the words that device that the direction inboard disposes (left side among Fig. 6) is compared with door that the reveal connecting portion 27b that makes the 1st transom 27 is in electro-motor 22, in this device, must be for fear of the interference of aforementioned reveal connecting portion 27b and electro-motor 22 and as shown in Figure 7 with the first half of this reveal connecting portion 27b towards the outside (right side among Fig. 7) expand, though this part is easy to generate the interference with other parts etc., but as the 1st embodiment, reveal connecting portion 27b is in the words in the outside of electro-motor 22 at any time with the location independent of door body 10A, just do not need aforementioned reveal connecting portion 27b is expanded (Fig. 4 reference), and the depth dimensions of its this partial devices is cut down.

Yet, by disposing as the 1st embodiment ground, though make the drive side connecting portion 27a of the 1st transom 27 be in the direction of principal axis front side of electro-motor 22 at any time, but this drive side connecting portion 27a has the shape of extending along belt 26 to get final product, because compare with aforementioned reveal connecting portion 27b, the front side that this drive side connecting portion 27a is disposed at the direct drive motor need height dimension less, so even also can influence device single-piece size hardly.

And, among the 1st embodiment, for the 2nd transom 28 its reveal connecting portions 28 also because with the location independent of door body 10B, at any time be in the outside (among Fig. 1 with the left side) of driven pulley 24, so the 2nd embodiment as described above, the inboard (right side among Fig. 6) that is in driven pulley 24 with the reveal connecting portion 28b of the 2nd transom 28 is different, need for the interference of avoiding this driven pulley 24 or the 1st transom 27 do not expanded in reveal connecting portion 28b front side (comparison) with reference to the reveal connecting portion 28b of Fig. 2 and the reveal connecting portion 28b of Fig. 7, for this point, also can carry out the reduction of device depth dimensions.

And, among the 1st embodiment, because will be disposed at 23,24 of two belt wheels, so can apply flexibly the space of 23,24 of this belt wheels effectively and organize in the opening and closing device controller 54 is light littlely for the controller 54 of the driving of controlling electro-motor 22.Particularly in the example of Fig. 3, because controller 54 is configured in two transoms 27,28 and belt 26 the dead aft the position and form the shape of the interference that can avoid these transoms 27,28 and belt 26, all suppress less one side controller gone in the device for 54 groups and can will install height dimension and depth dimensions on one side.
