Sliding door device
View Patent ↗A sliding door device includes 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, and a windbreak member that blocks a gap between the shaft and the slide door.
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.
2. The sliding door device according to claim 1 , further comprising:
a supporting member that supports the windbreak member.
