PROBLEM TO BE SOLVED: To provide a sliding door structure of a vehicle which is high in the degree of freedom of layout, while improving getting on and off with a simple structure.SOLUTION: A sliding door structure of a vehicle includes a lower rail 11 and a first arm 20. The first arm 20 has: a door side connection 23 coupled with a front end part 6a side of a slide door 6; a rail side connection 22 that slidably couples with the lower rail 11; and an arm body part 21 that is installed between the door side connection 23 and the rail side connection 22. The rail side connection 22 and the arm body part 21 are coupled so that both cannot turn mutually. The arm body part 21 is composed so that an angle &thetas;1 forward of the vehicle body among angles formed by a tangent T of the lower rail 11 at the position where the lower rail 11 and a rail side connection 22 couples becomes an acute angle. The rear end side of the lower rail 11 inclines to locate inside the vehicle width direction rather than the central part side of the lower rail 11. |
