Air-conditioning register

An air-conditioning register comprising:

• a tubular retainer that has an airflow passage;
• and
• a shut-off damper arranged in the retainer, wherein the shut-off damper is pivoted about a damper shaft between an opening position for opening the airflow passage and a closing position for closing the airflow passage, wherein
• the shut-off damper has a damper body having an outer peripheral edge section and a sealing portion that surrounds the outer peripheral edge section and is formed of a softer material than the damper body,
• the sealing portion includes two opposed side sections that are opposed to each other with the damper shaft located between the opposed side sections and extend parallel to the damper shaft and a distal sealing portion that is arranged at a position in each of the opposed side sections farthest from the outer peripheral edge section,
• the distal sealing portion contacts an inner wall surface of the retainer in an elastically deformed state at the closing position and is configured such that, if elastic deformation of the sealing portion did not happen, a section of each opposed side section would extend into the inner wall surface of the retainer at the closing position,
• the distal sealing portion includes a curved surface and a planar surface that extends continuously to the curved surface, wherein
• the curved surface is arranged on a trailing side in a pivoting direction of the shut-off damper from the opening position to the closing position in a manner projecting in the direction opposite to the pivoting direction,
• the planar surface is arranged on a leading side in the pivoting direction in a manner defining an acute angle with respect to a direction in which the two opposed side sections are opposed to each other,
• at least the planar surface of the distal sealing portion has a plurality of raised features protruding from the planar surface of the distal sealing portion, each having a height of 110 μm±50 μm, and
• the plurality of raised features is distributed across an entirety of the planar surface of the distal sealing portion.
