Register
In the register 1 of the embodiment, in case that all of the front side fins 41 are rotated to the upward direction, air flowing toward the air outlet 21 (air flow direction X) of the bezel 2 in the air flow path 3 A of the retainer 3 is blown out from the air outlet 21 of the bezel 2 and the blowout direction is changed to Y 1 . At that time, air flow separating from the concave surface existing on the lower surface of the front side fin 41 approaches to air flow along the concave surface existing on the upper surface of the front side fin 41 positioned at a lower position than that of the above front side fin 41 , and separates from the fixed fin 22 . Thereby, air with superior directivity to the upper direction can be obtained.
1. A register comprising:
a bezel having an air outlet formed therein;
a retainer having an air flow path along which an air flow toward the air outlet occurs and which communicates with the air outlet;
a movable fin for changing a blowout direction of air sent into the air flow path of the retainer and blown out from the air outlet, the movable fin having an upstream end and a downstream end;
a pair of rotational shafts for rotatably supporting the movable fin, the rotational shafts being formed at side ends of the movable fin and positioned at a downstream side along an air flow direction on the side ends; and
a fixed fin positioned near the air outlet of the bezel, the fixed fin having an upstream side and a downstream side;
wherein the downstream end of the movable fin is arranged near an edge position of the fixed fin positioned at the upstream side along the air flow direction, the downstream end and the edge position of the fixed fin being separated with a clearance therebetween,
wherein both upper and lower surfaces of the movable fin each include a concave surface which gradually curves from the upstream end to the downstream end, and
wherein a thickness of the movable fin narrows from the upstream end of the movable fin to a minimum thickness along the airflow direction at a position between the upstream end and the downstream end of the movable fin, and the thickness of the movable fin thickens from the minimum thickness from the position to the downstream end.
2. The register according to claim 1 , wherein a sectional shape of the fixed fin is formed so as to gradually become thinner from the upstream side toward the downstream side along the air flow direction.
3. The register according to claim 1 , wherein the downstream end and the edge position of the fixed fin positioned at the upstream side along the air flow direction has a parallel relation therebetween.
4. The register according to claim 1 , wherein the downstream end of the movable fin includes a convex shape and the edge position of the fixed fin includes a concave shape that corresponds to the convex shape of the downstream end.
5. A register comprising:
a bezel having an air outlet formed therein;

a pair of rotational shafts for rotatably supporting the movable fin, the rotational shafts being formed at side ends of the movable fin and positioned at a downstream side along an air flow direction on the side ends; and
a fixed fin positioned near the air outlet of the bezel, the fixed fin having an upstream side and a downstream side;
wherein the downstream end of the movable fin is arranged near an edge position of the fixed fin positioned at the upstream side along the air flow direction, the downstream end and the edge position of the fixed fin being separated with a clearance therebetween,
wherein the downstream end of the movable fin includes a convex shape and the edge position of the fixed fin includes a concave shape that corresponds to the convex shape of the downstream end, and
