Abstract
The present invention relates to a guide rail structure with which it is difficult to remove a slat from a guide rail using a bar or the like. In a guide rail having an outdoor sidewall, an opening side front wall, and a guide groove formed in said opening side front wall, a pocket space is formed in an indoor side of a slat end portion received in the guide rail and the pocket space permits deformation of said slat end portion towards an indoor side, a dimension of the pocket space is made larger than a width dimension of the guide groove, and said outdoor sidewall of the guide rail is set to a larger bending strength than the slat end portion, wherein when a force enlarging a gap between the outdoor sidewall and the slat end portion acts upon the outdoor sidewall and the slat end portion, the slat end portion is caused to deform in the pocket space before the outdoor sidewall deforms such that removal of the slat end portion from the guide groove is prevented by engaging the opening side front wall with the slat end portion that has been deformed in the pocket space.
