It is designed to rotate. A bezel (front cover member) 15 is attached to the front surface of the front cover member 2 so as to cover the front surface of the register body 1. A circular opening 15a for an operation knob is provided at the left end of the bezel 15, and the bezel 15 is attached so that the operation knob 5 protrudes forward from the circular opening 15a.

  The register having the above-described configuration is installed on the lower side of the instrument panel in the interior of the automobile. As shown in FIGS. 23 to 25, the installation state in the passenger compartment is such that the position of the register is on the lower side from the occupant's line of sight, and the bulging portion 21 of the front cover member 2 is located at the front of the register body 1. It is located so as to hide 20 from above, that is, to block the line of sight of the passenger.

  For this reason, to the passenger, the register outlet 20 becomes invisible, and the design of the register outlet 20 does not affect the design of the instrument panel. For this reason, when designing the design design of the whole instrument panel, the freedom degree will increase very much.

  When the register is used, the wind direction is adjusted by rotating (tilting) the operation knob 5 located on the left side of the front surface of the register body 1 up and down or left and right. As shown in FIG. 20, the air introduced from the introduction port 90 passes through the ventilation path 70 and is blown forward from the blower outlet 20, and the airflow is applied to the wall surface of the curved wall 22 of the bulging portion 21 located forward. It flows along and is blown forward.

  At this time, when the vertical position of the operation knob 5 is set to the center position as shown in FIGS. 20 and 23, the movable projecting fin 3 is slightly projected from the curved wall 22 of the bulging portion 21. At this time, the air flow blown from the air outlet flows along the wall surface of the curved wall of the bulging portion mainly due to the Coanda effect, and a part of the air flow is movable slightly protruding. It is peeled off from the wall surface by the projecting fins 3 and flows forward. For this reason, the air flow from the outlet 20 flows from the bulging portion 21 in the substantially front direction, and the wind direction is adjusted to the substantially front as shown in FIGS.

  On the other hand, when the vertical position of the operation knob 5 is rotated upward as shown in FIG. 21, the vertical rotation of the operation knob 5 is caused by the vertical rotation member 103, the rotation lever 102, and the link member of the operation knob mechanism 14. 101, which is transmitted to the movable projecting fin 3 via the arm portion 35, and rotates so that the movable projecting fin 3 is pulled back to the inside of the curved wall 22 of the bulging portion 21. At the same time, the movable auxiliary fin 6 is rotated by the operation of the second rotation transmission mechanism 12 so as to protrude toward the ventilation path 70 with the support shaft 61 as an axis.

  As a result, the movable projecting fin 3 is completely pulled back inside the curved wall 22 and the movable auxiliary fin 6 approaches the ventilation path 70 side. As shown in FIGS. The air flow blown from 20 flows under the bulging portion 21 so as to be compressed by the movable auxiliary fin 6 and pressed against the wall surface side. For this reason, the air flow flows along the wall surface of the curved wall 22 of the bulging portion 21 without peeling off due to the Coanda effect, and the air flow flows on the curved wall of the bulging portion 21. On the upper side, which is the direction of the wall surface 22, the air is blown with good directivity.

  On the other hand, when the vertical position of the operation knob 5 is rotated downward as shown in FIG. 22, the vertical rotation of the operation knob 5 causes the vertical rotation member 103, the rotation lever 102, and the link member of the operation knob mechanism 14. 101 is transmitted to the movable projecting fin 3 via the arm portion 35. At this time, the movable projecting fin 3 rotates so as to project downward from the curved wall 22 of the bulging portion 21 as shown in FIGS. At the same time, the movable auxiliary fin 6 is rotated back about its support shaft 61 by the operation of the second rotation transmission mechanism 12, and is stored in the fin storage portion 73.

  In this state, the air flow in the ventilation path 70 directly hits the curved wall 22 of the bulging portion 21 and flows along the wall surface, but the movable projecting fin 3 protrudes downward from the curved wall 22 of the bulging portion 21. Therefore, the air flow is peeled off from the wall surface and is blown downward as shown in FIG. 25 without producing the Coanda effect.

  On the other hand, when the operation knob 5 is moved to the left and right as shown in FIGS. 18 and 19, the left and right rotation member 106 in the operation knob mechanism 14 is rotated to the left and right. It is transmitted to the sector gear 131 via the link lever member 134 and the link member 133 of the transmission mechanism 13. The rotational force of the sector gear 131 is transmitted to the support shaft 81 of the rear fin 80 via the sector gear 85 on the rear movable louver 8 side, whereby the rear fin 80 of the rear movable louver 8 rotates to the left and right to send air. The direction is adjusted left and right. When the operation knob 5 is rotated to the left to the maximum angle, as shown in FIG. 19, the rear fin 80 of the rear movable louver 8 is rotated counterclockwise to the maximum angle in plan view, and the ventilation path 70 is closed. Is done.
