Abstract: An opening and closing structure for a vehicle includes a pair of guide rails and an opening and closing unit. The opening and closing unit includes a plurality of slats, a reinforcement, a first joint portion, and second joint portions. The plurality of slats are made of resin and arranged side by side in an extending direction of the guide rails. The reinforcement reinforces two of the slats that are adjacent to each other. The first joint portion is made of a flexible material which is more flexible than the resin forming the slats. The first joint portion joins the two adjacent slats. The second joint portions each join the two adjacent slats to the reinforcement. The reinforcement is configured to cover the second joint portions.
