Problems solved by technology

[0011] However, in Patent Document 1, the door-side lower rail 88 and the door-side center rail 89 are exposed to the interior of the vehicle compartment, thereby restricting the design and structure of the sliding door (eg, door trim).
[0012] On the other hand, in Patent Documents 2 and 3, the hinge 91 is used to open and close the sliding door, thereby limiting the opening and closing amount of the sliding door (so-called door stroke), and cannot be applied to sliding doors that require a large opening and closing amount.
