Abstract:
1. A sliding door device, comprising: a frame case that includes an opening through which an air flow passes; a slide door that is moved relative to the opening to adjust an aperture ratio of the opening; a shaft that is disposed at an upstream side of the slide door when viewed along the flowing direction of the air flow, and moves the slide door; a pinion gear that is fixed to the shaft; a rack gear that is installed in the slide door to be engaged with the pinion gear; and a windbreak member comprising a planar protrusion on the shaft that blocks a gap between the shaft and a face of the slide door; wherein the windbreak member extends outward in a radial direction of the shaft from a peripheral surface of the shaft; and wherein a height dimension in the radial direction of the windbreak member is greater than a height dimension in the radial direction of a tooth bottom of the pinion gear, and is smaller than a height dimension in the radial direction of a tooth top of the pinion gear so that the windbreak member approaches but does not contact the face of the slide door.
