In addition, since the plurality of vertical fins 31 connected to the vertical fins 32 by the connecting rods 38 also behave in the same manner as the vertical fins 32, they extend parallel to the vertical fins 32 and are positioned closer to the center of the register 1 toward the front side. will do. Similarly, the vertical fins 31 and 32 of the vertical fins 32 assembled in the retainer 10 on the right side are positioned closer to the center of the register 1 toward the front side.

As shown by the two-dot chain line in FIG. 7, in the left retainer 10, the air for air conditioning is blown out along the vertical fins 31 and 32 which are rotated so as to be positioned toward the center of the register 1 toward the front. Sprayed toward the left seat. In the retainer 10 on the right side, the air for air conditioning is blown out along the vertical fins 31 and 32 rotated so as to be positioned toward the center of the register 1 toward the front side, and is blown toward the seat on the right side of the front seat. As described above, the retainers 10 having the same configuration are arranged side by side in the left-right direction and arranged symmetrically with respect to the operation portion 40. Therefore, the left and right retainers 10 have the vertical fins 31 32 is rotated so that the widthwise interval between the downstream end portions becomes wider than the widthwise interval between the upstream end portions. As a result, the air for air conditioning blown out from the register 1 is blown out from the two retainers 10 so as to expand in the vehicle width direction toward the rear of the vehicle, and is blown toward the left and right front seats.

As shown in FIGS. 5 and 6, when the operation button 54 of the operation portion 40 is pushed forward, the slider 50 moves forward against the rearward biasing force of the spring 42 . An engaging portion 55 extending forward from the rear wall 51 of the slider 50 coaxially with the operating button 54 enters into the latch 41 assembled to the holder member 60 . The engaging portion 55 is engaged with the latch 41 while its forward movement is restricted by a heart cam mechanism provided inside the latch 41 .

As the slider 50 moves forward, the drive shaft portion 37 of the vertical fin 32 inserted into the insertion recess 58 also moves forward. As a result, in the vertical fins 32 assembled in the retainer 10 on the left side, the connecting arms 36 are positioned forward toward the center of the register 1 , and the vertical fins 32 are positioned toward the center of the register 1 toward the rear. will be located. A plurality of vertical fins 31 connected to the vertical fins 32 by connecting rods 38 behave in the same manner as the vertical fins 32, extend parallel to the vertical fins 32, and are positioned toward the center of the register 1 toward the rear. It will be. Similarly, the vertical fins 31 and 32 of the vertical fins 32 assembled in the retainer 10 on the right side are positioned closer to the center of the register 1 toward the rear side.

As indicated by the two-dot chain line in FIG. 8, in the left retainer 10, the air for air conditioning is blown out along the vertical fins 31 and 32 that are rotated so as to be positioned toward the center of the register 1 toward the rear, and the front seats Sprayed toward the aisle between the left and right seats. Also, in the right retainer 10, the air for air conditioning is blown out along the vertical fins 31, 32 which are rotated so as to be positioned toward the center of the register 1 toward the rear, and the air for air conditioning is blown into the passage between the left and right front seats. It is blown towards you. As described above, the retainers 10 having the same configuration are arranged side by side in the left-right direction and arranged symmetrically with respect to the operation unit 40. Therefore, the vertical fins 31 and 31 assembled to the left and right retainers 10 32 is rotated so that the vehicle width direction interval between the downstream end portions is narrower than the vehicle width direction interval between the upstream end portions. As a result, the air for air conditioning blown out from the register 1 is blown out from the two retainers 10 so as to narrow in the vehicle width direction toward the rear of the vehicle, and passes through the passage between the left and right front seats to the rear seat side. be sprayed.

When the operating button 54 is pushed forward again, the engagement between the heart cam structure in the latch 41 and the engaging portion 55 of the slider 50 is released, and the slider 50 is moved rearward by the rearward biasing force of the spring 42 . As a result, from the left and right retainers 10, the air for air conditioning is blown again so as to expand in the vehicle width direction towards the rear of the vehicle, and is blown onto the left and right front seats.

In this way, by operating the operation button 54, the direction of the air-conditioning air blown out from the left and right retainers 10 is directed toward the left and right front seats, and the state is directed rearward through the space between the left and right front seats. can be alternately switched between

According to the register 1 according to the first embodiment described above, the following effects can be obtained.
(1) The register 1 attached to the central portion of the instrument panel in the vehicle width direction has a pair of left and right retainers 10 arranged side by side in the vehicle width direction. A vertical fin group 30 composed of a plurality of vertical fins 31 and 32 respectively assembled inside the pair of left and right retainers 10 is simultaneously rotated by one operation button 54 .

Therefore, even if two retainers 10 are arranged side by side, the entire vertical fin group 30 can be rotated by one operation. It is not necessary to operate the vertical fin group 30 for each retainer 10, and the operability of the register 1 is improved.

(2) A common operating portion 40 is provided for two retainers 10 .
Therefore, the number of parts constituting the register 1 can be reduced. It is advantageous in terms of cost.

(3) The vertical fins 31, 32 of the retainer 10 on the left side and the vertical fins 31, 32 of the retainer 10 on the right side have a width in the vehicle width direction between the downstream ends larger than a width in the vehicle width direction between the upstream ends. The position is changed between a wide state and a state in which the vehicle width direction interval between the downstream end portions is narrower than the vehicle width direction interval between the upstream end portions. In a state in which the distance between the downstream ends in the vehicle width direction is wider than the distance between the upstream ends in the vehicle width direction, the air-conditioning air blown out from the two retainers 10 spreads in the vehicle width direction toward the rear of the vehicle. and sprayed onto each of the front sheets. Further, in a state in which the distance between the downstream end portions in the vehicle width direction is narrower than the distance between the upstream end portions in the vehicle width direction, the air-conditioning air blown out from the two retainers 10 moves toward the rear of the vehicle in the vehicle width direction. It is blown out so that it narrows to the rear seat.

Therefore, the direction in which the air-conditioning air is blown can be easily adjusted according to the situation.
(4) When the air-conditioning air is blown toward the rear of the vehicle so as to expand in the width direction of the vehicle, the air-conditioning air is integrated into one large flow when passing between the front seats.

Therefore, the air-conditioning air can easily reach farther, and can be suitably blown to the passengers sitting in the rear seats.
(5) By pressing the operation button 54, the operation unit 40 can switch between a state in which the air blows out in the vehicle width direction toward the rear of the vehicle and a state in which the air blows out in the vehicle width direction so as to narrow toward the rear of the vehicle. It can be switched alternately.

Therefore, it is not necessary to finely adjust the blowing direction of the air-conditioning air. The blowing direction of the air-conditioning air can be easily switched between two states according to the situation inside the vehicle.

(6) When arranging the register in the center of the vehicle width direction of the instrument panel, it may be necessary to arrange it in a narrow space under the panel such as the navigation system due to space constraints. If a register in which two retainers are arranged side by side in the vehicle width direction is arranged in such a space, it is difficult to see the rotational position of the fins and the position of the operating portion in the register. Further, in the case of a register having an operation portion for each retainer, it becomes complicated to adjust the rotational position of the fin to a desired position.

In this regard, in the register 1 of the above-described embodiment, the vertical fin groups 30 in the two retainers 10 can be operated with one operation unit 40, so even if it is arranged in a narrow space below the instrument panel, , adjustment of the rotation position of the vertical fin group 30 is easy. Moreover, since the two states are alternately switched by the operation button 54, the operation is simple.

(7) The operation button 54 is provided between the pair of outlets 21 of the bezel 20 and at the middle position of the bezel 20 in the left-right direction.
Therefore, the operation button 54 is provided at the middle position of the instrument panel in the vehicle width direction, and can be easily operated from both the driver's seat side and the passenger's seat side.

(8) Since the operation button 54 is provided at the middle position of the bezel 20 in the vehicle width direction, the vertical dimension of the register 1 can be reduced. As a result, the register 1 can be made thinner and can be easily applied to the limited space of the instrument panel.

(9) The bezel 20 assembled on the upstream side of the right retainer 10 and the bezel 20 assembled on the upstream side of the left retainer 10 are formed as an integral body arranged side by side in the vehicle width direction.

Therefore, the number of parts constituting the register 1 can be reduced.
