A regulator for regulating airflow through an air outlet includes a plurality of louver blades integrated with axis portions supported at bearing holes and interconnected through an interlocking member; a supporting plate with the bearing holes attached to an air outlet; and an elastic portion provided on the supporting plate to be capable of deforming along an axis of the louver blades. Also, the regulator may include a damper; a manual operating member for tilting the louver blades and damper; and two gears engaging each other and disposed at an interconnecting portion between the manual operating member and the damper. One of the gears is formed in two portions separated along an axis and provided coaxially. The two portions have slightly shifted pitch, and are able to displace with each other in a circumferential direction with elasticity.

1. A regulator for regulating airflow in an air outlet, comprising:a case having a flange with the air outlet,a plurality of louver blades arranged at the air outlet for controlling a direction of the airflow and having axes at longitudinal ends,at least one interconnecting member connected to the louver blades for changing directions of the louver blades, anda supporting member attached to the flange at the air outlet and having axis holes for receiving the axes of the louver blades, said supporting member having elastic portions formed at two longitudinal ends thereof for allowing deformation in an axis direction of the louver blades. 2. A regulator according to claim 1, wherein each of said elastic portion has a branched shape, an end of which contacts the flange. 3. A regulator according to claim 1, further comprising an operating member rotatably supported on the case and having a shaft, said operating member being connected to the interconnecting member for tilting the louver blades, and rotational resistance applying means provided around the shaft of the operating member. 4. A regulator according to claim 3, wherein said rotational resistance applying means is formed of an O-ring between the shaft and a support thereof. 5. A regulator according to claim 4, wherein said O-ring is formed of a silicone resin having self-lubricity. 6. A regulator according to claim 1, further comprising an operating member rotatably supported on the case for tilting the louver blades, and an interconnecting member disposed between the louver blades and the operating member and having long holes for receiving pins of the louver blades, each of said long holes having a long axis parallel to a straight line between a middle point of a rotational range of the pin and the rotational center of the louver blade. 7. A regulator for regulating airflow in an air outlet, comprising:a case having the air outlet and an air path,a plurality of louver blades arranged at the air outlet for controlling a direction of the airflow,a damper disposed in the air path of the case for opening and closing the air path,an operating member rotatably attached to the case and connected to the louver blades and the damper for tilting the same, andconnecting means for connecting the damper to the operating member and having first and second gear portions meshing each other and connected to the operating member and the damper, one of said first and second gear portions having divided gear teeth portions perpendicular to a shaft thereof, said divided gear teeth portions having pitches slightly offset in a circumference direction with each other so that the two gear teeth portions displace in the circumference direction when the first and second gear portions engage with each other. 8. A regulator according to claim 7, wherein said connecting means further includes a lever connected to the damper with a pin, and an arm rotationally attached to the case and having an elongated hole engaging the pin of the lever, said one of the first and second gear portions being formed on the arm away from the elongated hole. 9. A regulator according to claim 8, further comprising an interlocking member connected to the louver blades for changing directions thereof, said interlocking member being connected to the operation member. 10. A regulator for regulating airflow in an air outlet, comprising:a case having the air outlet and an air path,a plurality of louver blades arranged at the air outlet for controlling a direction of the airflow, each louver blade having a rotational center and a pin projecting at a position away from the rotational center,an operating member rotatably supported on the case for tilting the louver blades, andan interconnecting member disposed between the louver blades and the operating member and directly engaging the louver blades, said interconnecting member having long holes, each of said long holes receiving the pin of each louver blade and having a long axi s parallel to a straight line between a middle point of a rotational range of the pin and the rotational center of the louver blade. 11. A regulator according to claim 10, wherein said long hole is inclined with respect to the pin so that when the interconnecting member is operated, the pin is pushed to tilt the louver blade around the rotational center.
