Abstract: An opening and closing device includes a casing that defines an air passage, a slide door that includes a door main body slidable to open or close the air passage, and a sliding gear that is disposed on one side of the door main body in its width direction and includes first teeth in a sliding direction, and a drive gear that is rotatable around its axis line extending in the width direction and that includes second teeth in a circumferential direction around the axis line such that the first teeth and the second teeth are arranged in engagement with each other. When the drive gear rotates, a driving force is transmitted from the drive gear to the slide door through the sliding gear to slide the slide door. The door main body is restricted from shifting in the width direction due to the rotation of the drive gear.
