<p>PROBLEM TO BE SOLVED: To provide a slide door device capable of reducing liquid remaining on a surface of a rail, and thus maintaining quality of the surface of the rail and an outer peripheral surface of a roller for a long time.SOLUTION: The slide door device includes: a horizontal rail part 40 for guiding a slide door D provided at a vehicle body; and a vertical roller 2 fixed to the slide door D through a lower arm 1, for receiving the load of the slide door D and rotating on a surface of the horizontal rail part 40 when the door is opened/closed. The vertical roller 2 is composed of a rolling bearing having: an inner race 21; an outer race 23 and an outer skin part 24 disposed on an outer diameter side of the inner race 21, for rotating on the surface of the horizontal rail part 40; and balls 22 for rolling on a raceway surface between the inner and outer races. On an outer peripheral surface of the outer skin part 24, there are formed inclined grooves 24a being recessed continuously between both ends in an axial direction, and an inclination direction of each of the inclined grooves 24a is configured so that one of both ends goes ahead when the vertical roller 2 rotates with the slide door D being opened/closed.</p> |
