Problems solved by technology

For this reason, the sliding type passenger compartment opening / closing door in the related art has the following problems: the weight of the vehicle is increased and the number of components is increased, and the degree of freedom in the design of the vehicle is deteriorated
This has the problem of rotating the sliding door about an imaginary axis X connecting the contact points
In addition, the support point for the sliding door is formed only on the imaginary axis X, so when the load of the sliding door is applied, only one contact point A remains in the direction of the load (direction of the imaginary axis X), so the sliding door cannot be supported stably. Door

Embodiment approach

[0049] The floor space 150 is a space formed in advance when designing a vehicle on which the sliding door is installed, and the first lower rail 110 and the second lower rail 120 are not exposed outside the floor space 150 (outside of an open portion of the floor space). Therefore, according to the exemplary embodiment of the present invention, the vehicle in which the sliding door is installed is excellent in appearance, there is no obstacle in the moving route when the user gets on or off the car, and the floor space formed in the related art 150 may be used to install the first lower rail 110 and the second lower rail 120 without changing the design of the vehicle body 2 .

[0050] refer to Figure 7 , the first lower rail roller unit 130 is rollably connected to the first lower rail 110 . Specifically, the first roller 132 of the first lower rail roller unit 130 is inserted into the first roller insertion portion 112 of the first lower rail 110 . The first roller 132 ma...
