The axis connecting the pair of connecting pin portions 212, 212 substantially coincides with the central axis of the spherical joint 11, and the drive main body 211 is in a position to be inserted into the groove 153 of the guide arm 15. In the connecting portion 213, a connecting arm 22 that is connected to the pin portion 71 of one front fin 7 is disposed.

  The second drive unit 30 includes a guide arm 15, a joint arm 31 inserted through the hollow portion 151 a of the guide arm 15, a back fin operation link 32 connected at one end of the joint arm 31, and a back fin operation link 32. And a connecting arm 33 that is connected to the other end and rotates the back fin 9. The connecting arm 33 may be a two-armed arm disposed on the upper part of the adjacent back fin 9 or may be directly connected to the pin portion 91 of the adjacent back fin 9. In the embodiment, two arm portions 331 and 331 extending around the pin portion 91 of the back fin 9 are provided.

  The joint arm 31 is connected to the body portion 311 formed in a curved shape, the pivot portions 312 and 313 supported rotatably on the upper and lower wall portions of the sub-retainer 4, and the upper fin portion 312, and is connected to the back fin operation link 32. And a connecting lever portion 314 to be connected. A connecting pin portion 315 is formed at the tip of the connecting lever portion 314 so as to extend upward. The body portion 311 is formed with a width that can be inserted into the hollow portion 151 a of the guide arm 15, and has a width that can be sandwiched between the pair of projecting portions 154 and 154 of the guide arm 15. Further, a support portion 316 into which the extended portion 112 of the spherical joint 11 is fitted is formed on the inner surface of the central portion of the body portion 311 so as to protrude to the spherical joint 11 side.

  The back fin operation link 32 has arm portions 321 and 321 that extend in two directions to form a character shape, and is supported on the upper wall of the sub-retainer 4 so as to be rotatable by a pivot 322. Long grooves 323 and 323 are formed in the arm portions 321 and 321 along the longitudinal direction of the arm portions 321 and 321.

  In the embodiment, the connecting arm 33 has a pair of arm portions 331 and is pivotally attached to the pin portion 91 that is the center of rotation of the back fin 9 so as to be swingable about the pin portion 91. Yes. One arm portion 331 is formed with a connecting pin portion 332 slidably connected to one long groove 323 formed in the back fin operation link 32. The other arm portion 331 is connected to a back fin connecting rod 34 (see FIG. 2) for simultaneously turning all the back fins 9 in the same direction.

  Further, as shown in FIG. 2, a damper plate 41 is disposed at the rear portion of the retainer 3 so that the hollow portion in the retainer 3 can be opened and closed by operating the operation handle 42 for the damper plate 41.

  Next, the operation of the register 1 configured as described above will be described.

  First, the first rotation drive unit 20 is driven, and the front fin 7 is moved from the horizontal position as shown in FIG. 6 to any one of the vertical directions (downward in FIG. 7) as shown in FIG. A case of rotating will be described. When the knob plate 13 of the operation knob 12 shown in FIG. 8 is pushed downward and the operation knob 12 is rotated downward, the operation knob 12 is rotated clockwise around the spherical joint 11 as shown in FIG. Rotate to. Then, the main body 151 of the guide arm 15 (see FIG. 4) locked to the fitting portion 121 of the operation knob 12 by the claw portions 152, 152 is centered on the spherical joint 11, as shown in FIG. Rotate upward. The upward rotation of the main body portion 151 of the guide arm 15 causes the drive main body portion 211 of the front fin actuation link 21 fitted in the first groove portion 153 of the main body portion 151 of the guide arm 15 to move to the connecting pin portions 212 and 212. Rotate upward (see FIG. 4) as a center.

  Since the connecting portion 213 is arranged on the front fin operating link 21 and is connected to the front fin 7 via the connecting arm 22, the rotation of the front fin operating link 21 upward of the drive main body 211 is connected to the connecting arm 22. One end of this is rotated upward. Since the other end of the connecting arm 22 is pivotally attached to the pin portion 71 of the front fin 7, the pin portion 71 is rotated clockwise in FIG. It will be turned toward. In this state, the damper plate 41 is in a state of rotating in the horizontal direction and opening the retainer 3 because air is introduced. Therefore, the wind direction flowing into the retainer 3 can be adjusted downward in the vehicle.

  On the other hand, the vertical rotation of the main body 151 of the guide arm 15 is not transmitted to the joint arm 31 inserted through the hollow portion (second groove portion) 151 a of the guide arm 15. That is, when the guide arm 15 moves up and down, the protrusion 154 of the guide arm 15 only slides on the side surface of the joint arm 31 and does not apply a force to move the joint arm 31 in the vertical direction. As a result, the back fin operation link 32 is not operated, and therefore the back fin 9 does not rotate in the vertical direction.

  Next, a case will be described in which the back fin 9 is rotated from a straight position as shown in FIG. 9 to either the left or right direction of the front view (left in FIG. 10) as shown in FIG. . When the knob plate 13 of the operation knob 12 shown in FIG. 8 is rotated toward the left by pressing the arrow portion indicating the left side, the operation knob 12 moves around the spherical joint 11 as shown in FIG. Rotate clockwise. That is, when the knob plate 13 of the operation knob 12 is rotated leftward, the operation knob 12 rotates leftward about the spherical joint 11. The guide arm 15 locked to the fitting portion 121 of the operation knob 12 by the claw portion 152 rotates in the clockwise direction in FIG. Since the guide arm 15 sandwiches the side surface portion of the joint arm 31 with the pair of projecting portions 154 and 154, the guide arm 15 is rotated in the left-right direction by using the extending portion 112 disposed in the spherical joint 11. Accordingly, the body 311 of the joint arm 31 is rotated clockwise in FIG. The clockwise rotation of the body portion 311 of the joint arm 31 rotates the upper pivot portion 312 pivotally supported by the sub-retainer 4 and the connecting lever portion 314 coupled to the pivot portion 312 in the clockwise direction. The pin portion 315 slides in one long groove 323 of the back fin operation link 32 to rotate the arm portion 321 of the back fin operation link 32 counterclockwise around the pivot 322.

  The counterclockwise rotation of the arm portion 321 includes rotating the arm portion 331 in the clockwise direction around the pin portion 91 of the back fin 9 by the connecting arm 33 that slides in the other long groove 323 with the connecting pin portion 332. Become. Thereby, the back fin 9 is rotated clockwise in FIG. Since the back fin connecting rod 34 is connected to the other end of the connecting arm 33, the back fin connecting rod 34 is moved in the left direction in FIG. 10 by rotating one back fin 9 clockwise. Then, the other back fins 9 are simultaneously rotated in the same direction. In this state, the damper plate 41 is in a state of rotating in the horizontal direction and opening the retainer 3 because air is introduced. Therefore, the wind direction flowing into the retainer 3 can be adjusted to the left of the vehicle.

  On the other hand, the rotation of the guide arm 15 in the left-right direction is not transmitted to the front fin operation link 21 inserted through the first groove portion 153 of the guide arm 15. That is, when the guide arm 15 rotates in the left-right direction, the first groove portion 153 of the guide arm 15 only slides on the upper and lower surfaces of the body portion 311 of the joint arm 31, and the joint arm 31 is moved in the left-right direction. Do not give the force to move to. As a result, the back fin operation link 32 is not operated in the left-right direction, and therefore the front fin 7 does not rotate in the up-down direction.

  As a result, the front fin 7 and the back fin 9 of the register 1 are adjusted to an appropriate position in an independent state by operating the operation knob 12.

  As described above, in the register 1 of the embodiment, the wind direction of the front fin 7 and the back fin 9 can be adjusted independently of each other by rotating the single operation knob 12 in the vertical or horizontal direction. . That is, the guide arm 15 as the first rotation drive body moves the front fin operating link 21 up and down to rotate the front fin 7 in the up and down direction. When the front fin 7 is rotated in the vertical direction on the guide arm 15, the hollow portion (second relief groove) 151 a only slides on the joint arm 31 inserted through the first relief groove 153. The joint arm 31 is not transmitted up and down drive. Since there is no vertical movement of the joint arm 31, the back fin 9 is not rotated in the vertical direction.

  Further, when the back fin 9 is rotated in the left-right direction, the guide arm 15 rotates the joint arm 31 in the left-right direction and rotates the back fin 9 in the left-right direction via the back fin operation link 32. Then, when the back fin 9 is rotated in the left-right direction, the first arm 153 slides on the guide arm 15 only by sliding the front fin operation link 31 inserted through the first groove 153. The rotation in the left-right direction is not transmitted to the operation link 3. Since there is no left-right movement of the front fin operation link 31, the front fin 7 is not rotated in the left-right direction.

  Therefore, the operation of rotating the front fin 7 by the first driving means 20 and the operation of rotating the back fin 9 by the second driving means 30 are made independent of each other by avoiding mutual interference with the single operation knob 12. Therefore, the operation unit 10 can be configured safely without being damaged. Moreover, since it is configured in a compact manner, it is possible to provide a horizontally long register 1, for example, by configuring the register 1 in a compact manner and securing it in a small space for the vehicle. Therefore, improvement on the design surface can be achieved.

  Moreover, since the spherical joint 11 can be used for the operation part 10, it can perform smooth operation and can obtain high stability with respect to the load at the time of operation.

  In addition, this invention is not limited to the above-mentioned form. For example, the joint arm as the second rotational driving body may be directly connected to the operation unit 10 and driven without the guide arm 15 interposed.

  Further, as the escape means formed in the rotation drive means, when the front fin is driven in the front-rear direction, the front fin operation link is not required even if it is not the first groove portion and the second groove portion formed in the guide arm. Any configuration may be used as long as it does not transmit the drive in the left-right direction, or does not transmit the drive in the vertical direction of the joint arm when driving the back fin in the left-right direction.
