Abstract
Provided is a register that can more surely suppress abnormal noise caused by air passing through a space between a damper and a retainer. An inner wall of an upper side wall of the retainer is formed with a plurality of rib parts provided on a downstream side relative to an outer periphery on the downstream side of a plate member in a closed state of a damper. The plurality of rib parts is arranged in a direction parallel to a turning axis of the damper, and adjacent rib parts are formed into different shapes. A soft seal member is provided with a plurality of protrusion parts on an upper surface of the outer periphery on the downstream side of the plate member.
