  Next, the 180 ° rotation unit 22 will be described in the left-right direction. The angle changing columnar body 10 is rotated about the central axis in the long axis direction at the end face portion of the angle changing columnar body 10 on the wheelchair attachment portion 2 side, so that the angle changing columnar body 10 rotates in one direction. The long axis direction of the changed part can be directed to any of the left and right directions in plan view. Therefore, since the connecting device 1 can reverse the connecting portion 4 by 180 ° in the left-right direction, it is attached to either the right side frame or the left side frame of the moving body 80 such as a wheelchair Since the moving body 90 does not easily get in the way, it is possible to more safely push the moving body 80 such as a wheelchair while pulling on the follow-up moving body 90 of the drip tray.

  First, as shown in FIG. 19 and FIG. 20, the configuration of the 180 ° rotation unit 22 in the left-right direction will be described in the form of a model showing a configuration in which the rotation side can rotate 180 ° with respect to the fixed side.

  First, the fixed side is the fixed cylindrical body 101, and the rotation side is in the form of a combination of a portion in the same major axis direction as the longitudinal direction of the moving body 80 with a wheelchair and the angle change column 102 having the angle change portion 108 There is one form 100. In this case, the angle-changing columnar body 102 shown in FIG. 19B is inserted into the fixed cylindrical body 101, and the length of the end surface portion 103 of the angle-changing columnar body 102 on the wheelchair attachment portion 2 side is Rotate around the axial center axis. When mounting the connecting device 1 on the right side of the wheelchair 80, as shown in FIG. 19 (a), it is possible to change the angle to the right with respect to the front-rear direction of the mobile unit 80 as a wheelchair. When mounted on the left side of 80, as shown in FIG. 19 (c), the angle changed to the left with respect to the front-rear direction of the wheelchair moving body 80 is easy by rotating the angle changing columnar body 102 by 180 °. You can 19 (a) and 19 (c) show the peripheral wall of the fixed cylindrical body 101 in a transparent state in order to make it easy to understand the positional relationship between the fixed cylindrical body 101 and the angle change columnar body 102, and FIG. The end face shape for making it easy to understand the shape of the fixed cylindrical body 101 and the angle change columnar body 102 is described.

  Second, the end face portion 114 is an angle-changed portion 118 where the fixed side is the fixed columnar body 111 shown in FIG. There is a second embodiment 110 in the form of a combination with the angle change columnar body 112 shown in FIG. In this case, the angle change columnar body 112 brings the end surface portion 114 which is the angle change portion 118 and the end surface of the fixed columnar body 111 into surface contact, and the movable body attachment portion 2 side of the angle change columnar body 112 Of the end face portion 114 in the longitudinal direction. When mounting the connecting device 1 on the right side of the wheelchair 80 as shown in FIG. 20 (a), the angle can be changed to the right with respect to the front-rear direction of the wheelchair 80, as shown in FIG. 20 (e) When the wheel 1 is mounted on the left side of the wheelchair 80, the angle change to the left side with respect to the front-rear direction of the moving body 80 as a wheelchair can be facilitated by rotating the angle change columnar body 112 by 180 °.
