ON-VEHICLE SLIDING DOOR DEVICE AND A VEHICLE HAVING ON-VEHICLE SLIDING DOOR DEVICE

PROBLEM TO BE SOLVED: To provide an on-vehicle sliding door device capable of reducing vibrations and noises of the sliding door with a simple structure and to provide a vehicle including the on-vehicle sliding door device.SOLUTION: The on-vehicle sliding door device includes: a sliding door rail 5 which is formed along a movement direction; and a sliding door 3 which has an engagement part 3a engaging with the sliding door rail 5 and which is opened/closed by a movement of the engagement part 3a along the sliding door rail 5. The sliding door rail 5 has a rattle prevention part 8 in a region of an end part 70 corresponding to the close position of the sliding door 3, in which a gap 90b between the engagement part 3a of the sliding door 3 and the sliding door rail 5 is smaller than a gap 90a between the engagement part 3a of the sliding door 3 and the sliding door rail 5 in other area. 【課題】簡易な構造で、引戸の振動および騒音を抑制することが可能な車両用引戸装置および車両用引戸装置を備える車両を提供する。【解決手段】移動方向に沿って形成される引戸レール５と、引戸レール５との係合部３ａを有し、係合部３ａが引戸レール５に沿って移動することで開閉する引戸３と、を備え、引戸レール５は引戸３の閉位置に対応する端部７０の領域に、他の部分での引戸３の係合部３ａと引戸レール５との間隔９０ａよりも、引戸３の係合部３ａと引戸レール５との間隔９０ｂが狭いがたつき防止部８を有する。【選択図】図４
