An annular groove-shaped guide portion 35 that is movably guided is formed. That is, the guide part 35 is formed in a circumferential shape (arc shape) with the axial direction of the case body 11, which is the direction in which the wind passes through the case body 11, as the central axis.

  Hereinafter, the circumferential direction of the case body 11 is a direction along an arc centered on the central axis on a plane orthogonal to the central axis of the case body 11, that is, a direction along the outer periphery of the vent 31. Shall be said.

  Each spacer 12 has a flat rectangular parallelepiped shape, and is disposed at a position that is point-symmetric with respect to the opposite position of the guide portion 35, in other words, the center of the guide portion 35 (the center of the vent 31). ing. Further, the spacers 12 are provided with projections 12c having a semicircular cross section at the four corners of the one main surface 12a and the other main surface 12b, and the central portions of the one main surface 12a and the other main surface 12b. A through hole 12d is formed as a bearing portion.

  One sliding surface 12e has a central angle set at 90 °, for example. The other sliding surface 12f is formed to have a larger diameter than the one sliding surface 12e, and the central angle is set to 270 °, for example. The one and other sliding surfaces 12e and 12f are concentrically positioned with respect to the central portion of one main surface 12a (other main surface 12b).

And the other end are formed in a straight line (planar shape) and are separated from each other by 90 °, for example.

  Further, the protrusion 12c protruding from the one main surface 12a is a portion where the outer frame portion 27b constituting the guide portion 35 and the tip side abut in a dotted (linear) shape, and protruded from the other main surface 12b. The protrusion 12c is a portion that contacts the fin 13 side. That is, these protrusions 12c suppress the sliding resistance of the spacer 12 with respect to the guide portion 35 (case body 11) and the fins 13.

  The front side protrusions 27c and the rear side protrusions 33c of the case body 11 are in contact with the side surfaces 12i and 12i positioned in the front and rear of the spacer 12 in a dotted (linear) manner.

  The fin 13 is also called a blade body, a housing, or a louver, and controls the air direction and the amount of air blown from the air direction adjusting device 10. For example, the fins 13 are formed in substantially the same diameter and form a pair separated from each other in parallel. A blade-shaped central blade portion 13c that is positioned substantially parallel between the blade portions 13a and 13b and has a larger diameter than the blade portions 13a and 13b, which are disk-shaped rectifying portions. The blade portions 13a to 13c are connected to each other at a position facing each other by the connecting portions 13d and 13d, for example, the upper and lower positions, and are integrated. Therefore, air holes 13e and 13f are formed between the blade portions 13a and 13b and the central blade portion 13c, and the direction along the blade portions 13a to 13c is the direction of the wind controlled by the fins 13. It has become a wind axis. Further, shaft portions 13g and 13g as support shafts are projected from the coupling portions 13d and 13d, respectively.

  The outer diameter of the central blade portion 13c is set to be approximately equal to the diameter of the communication port 25 and the ventilation port 31.

  Each shaft portion 13g integrally includes a circular shaft main body portion 13h in plan view and a protruding shaft portion 13i that protrudes in a fan shape from the shaft main body portion 13h in plan view. Then, the outer peripheral surface of the shaft main body portion 13h is one shaft portion sliding surface 13j having a circumferential surface that is in sliding contact with one sliding surface 12e of each spacer 12, and the outer peripheral surface of the protruding shaft portion 13i is The other shaft portion sliding surface 13k of the circumferential surface is in sliding contact with the other sliding surface 12f of each spacer 12, and one shaft portion sliding of the shaft main body portion 13h of the protruding shaft portion 13i The side surfaces protruding from the surface 13j are planar one and other abutting surfaces 13l and 13m that can abut against one and the other stopper surfaces 12g and 12h, respectively.

  One shaft portion sliding surface 13j is larger in diameter than the other shaft portion sliding surface 13k, and the central angle is set at, for example, 270 °. The other shaft portion sliding surface 13k has a central angle set at 90 °, for example. The one and other shaft sliding surfaces 13j, 13k are located concentrically with respect to the central portion of the shaft main body 13h.

  The one and the other abutment surfaces 13l and 13m, together with the one and the other stopper surfaces 12g and 12h, regulate the rotation angle of the fin 13 with respect to each spacer 12, and the one shaft portion sliding surface 13j. Are formed in a straight line (planar shape) extending between one end and the other end of the other and one end and the other end of the other shaft portion sliding surface 13k, and are separated from each other by, for example, 90 °. Accordingly, the fins 13 can be rotated 360 ° in the circumferential direction of the case body 11 together with the spacers 12, and the direction different from the rotation direction (crossed (orthogonal)) with respect to the spacers 12, that is, It is possible to rotate 180 ° in the left-right direction (the direction perpendicular to the cylinder of the case body 11), which is the direction in which the rotation axis intersects (orthogonal) with respect to the rotation axis in the rotation direction.

  When assembling the wind direction adjusting device 10, first, the spacers 12 and 12 are attached to the shaft portions 13g and 13g of the fin 13 (FIG. 1). At this time, the shaft portion 13g is inserted into the through hole 12d so that the shaft portion sliding surfaces 13j and 13k of the shaft portions 13g are held by the sliding surfaces 12e and 12f of the spacers 12. In this state, the tip side of each protrusion 12c formed on the other main surface 12b of each spacer 12 comes into contact with the connecting portion 13d of the fin 13 in a linear (dotted) manner.

  Next, the fins 13 to which the spacers 12 and 12 are attached are sandwiched from the front and rear by the case main body 21 and the finisher 22 (FIG. 3), so that the spacers 12 and 12 are positioned at the guide portions 35 and the front protrusions 27c. And the rear protrusion 33c are in linear contact with the front and rear (dots) on the front end side, and the front end side of each protrusion 12c of one main surface 12a of each spacer 12 is linear with the inner peripheral surface 27e of the frame 27 Abuts (dot). As a result, the wind direction adjusting device 10 in which the fins 13 can rotate in the circumferential direction of the case body 11 along the guide portions 35 through the spacers 12 and the fins 13 can rotate with respect to the spacers 12 is provided. Complete.

  And the wind direction adjustment apparatus 10 installed in the to-be-installed part of the interior member of a motor vehicle made the fin 13 the neutral (neutral) position, ie, a fully open state, as shown to FIG. 6 (a1) and FIG. 6 (b1). At this time, the wind axis of the fin 13 is parallel to the central axis of the case body 11. At this time, in each shaft portion 13g, the shaft portion sliding surfaces 13j and 13k are held by the sliding surfaces 12e and 12f of the spacers 12, and the contact surfaces 13l and 13m are separated from the stopper surfaces 12g and 12h. The wind flows from the vent 31 toward the front of the occupant.

  In addition, as shown in FIGS. 6A2 and 6B2, when the fin 13 is rotated leftward (arrow A direction) from the neutral position, the fin 13 is the central axis of the case body 11. On the other hand, the blade portions 13a and 13b and the central blade portion 13c, that is, the positions where the wind axes intersect. At this time, each shaft portion 13g is rotatable to a position where one abutting surface 13l abuts against one stopper surface 12g, that is, 90 °, and these one abutting surface 13l and one stopper surface 12g The wind axis is substantially perpendicular to the central axis of the case body 11, the blade 13a closes the communication port 25, and the wind does not blow out from the vent 31 (all Closed).

  Further, as shown in FIGS. 6 (a3) and 6 (b3), when the fin 13 is rotated rightward (arrow B direction) from the neutral position, the fin 13 is the central axis of the case body 11. On the other hand, the blade portions 13a and 13b and the central blade portion 13c, that is, the positions where the wind axes intersect. At this time, each shaft portion 13g can be rotated by 90 ° to the position where the other contact surface 13m contacts the other stopper surface 12h, that is, the other contact surface 13m and the other stopper surface 12h The wind axis is substantially perpendicular to the central axis of the case body 11, the blade portion 13b closes the communication port 25, and the wind does not blow out from the vent port 31 (all Closed).

  The fin 13 may be configured to be capable of rotating 360 ° in the left-right direction without providing the contact surfaces 13l and 13m of the shaft portion 13g of the fin 13 and the stopper surfaces 12g and 12h of the spacer 12.

  In addition to rotating the fins 13 in these left and right directions, a combination of actions to rotate the case body 11 appropriately in the circumferential direction (arrow C direction), that is, in the direction in which the wind passes, The direction of the wind blown from the mouth 31 can be freely changed in three dimensions. That is, by twisting the fin 13 in the circumferential direction, one spacer 12 moves in one direction, whereas the other spacer 12 moves in the direction opposite to the moving direction of one spacer 12 with respect to the center. As a result, the fin 13 rotates in the circumferential direction.

  As described above, according to the present embodiment, the fin 13 is moved in the moving direction of the spacer 12 with respect to the spacer 12 that is movably guided along the guide portion 35 formed in the arc shape of the case body 11. The fins 13 can be movably supported in the direction along the guide portion 35 (circumferential direction) and in the direction different from this direction (left-right direction) by the spacer 12 alone. Therefore, compared with the configuration including parts that support the fins movably corresponding to each of these directions, the number of parts can be reduced, the assembly man-hours can be reduced, the workability of assembly, the mold production cost, etc. The total cost can be reduced.

  Further, the guide portion 35 guides each spacer 12 so as to be movable in the front-rear direction around which the wind of the case body 11 passes, that is, along the circumferential direction of the case body 11, and through holes of each spacer 12. 12d is supported in a wide area by the fin 43 by combining each of the shaft portions 13g of the fin 13 so as to be rotatable in a direction (right and left direction) intersecting (orthogonal) with the direction in which the wind of the case body 11 passes. A wide air distribution range.

  Further, the fin 13 can be fully closed by blocking the air blown out from the vent 31 by rotating leftward or rightward to the maximum, that is, the closing operation of the fin 13 is bidirectional. Therefore, it is possible to obtain a wide range of air distribution performance, and even if the fin 13 is rotated in either the left direction or the right direction, it can be in the fully closed position, so a comfortable closing operation is possible. Can be obtained.

  The main surface 12a and the other main surface 12b of the spacer 12 are provided with projections 12c that are brought into contact with the guide portion 35 and the fin 13, and the side surfaces 12i of the spacer 12 are provided on the case body 21 and the finisher 22 that constitute the guide portion 35. By providing the front protrusion 27c and the rear protrusion 33c to be brought into contact with 12i, the amount of protrusion of these protrusions 12c and protrusions 27c, 33c can be adjusted so that the spacer 12 can be attached to the guide part 35. The sliding resistance of the spacer 12 with respect to the guide portion 35 can be appropriately set while preventing rattling in all directions, and more reliable air distribution performance can be obtained.

  In addition, friction between the spacers 12 and the guide portions 35 can be achieved by pivotally supporting the shaft portions 13g of the fins 13 in the through holes 12d of the spacers 12 disposed at the opposing positions of the guide portions 35, respectively. By appropriately setting the force, that is, the sliding resistance (matching), it is possible to manage the operation torque for rotating the fin 13 in the circumferential direction, and the frictional force between the through hole 12d and each shaft portion 13g, that is, the sliding resistance. By appropriately setting (matching), the operation torque for turning the fin 13 in the left-right direction can be managed, so that the operation torque for the fin 13 can be managed reliably and easily. In other words, the operation torque of the fins 13 can be reliably managed by managing the manufacturing accuracy of each spacer 12.

In addition, a plurality of rear ribs 33e serving as (other) contact projecting portions project from the front surface of the opposing projecting plate portion 33a of the finisher 22. In other words, these ribs 27f and 33e are located in front of and behind the guide portion 35, and radiate along the radial direction of the guide portion 35, in other words, in a direction intersecting the guide direction of the spacer 12 by the guide portion 35. And are spaced apart from each other in the circumferential direction of the case body 11, in other words, in the guide direction of the spacer 12 by the guide portion 35, by a dimension substantially equal to the width dimension of the convex portion 12k. The ribs 27f and 33e are formed in a semicircular shape in cross section, and are positioned to face each other in the front-rear direction.

  Then, in the assembled state of the wind direction adjusting device 10, as shown in FIG. 9, the side surfaces 12i, 12i of the spacer 12 face the front rib 27f and the rear rib 33e, respectively, and adjacent front ribs 27f, 27f.

  The accommodating portion 58 is formed in a spherical shape having a maximum diameter dimension larger than the diameter dimension of the main body portion 57 continuously from the rear end portion of the main body portion 57. In addition, one and the other guide groove portions 61 and 62 are elongated along the front-rear direction and along the circumferential direction of the accommodating portion 58 at the upper portion and the lower portion that are portions of the accommodating portion 58 that face each other. Each is formed in an arc shape. These guide groove portions 61 and 62 are formed at positions outside the inner peripheral surface of the accommodating portion 58. Further, at the position of the front end portion of these guide groove portions 61 and 62, one of the step-like restriction that restricts the forward rotation position of the fin 43 at the position where the accommodating portion 58 and the main body portion 57 are continuous is restricted. One and the other stopper surfaces 61a and 62a are formed as portions. Further, a locking recess 58a, which is a locking portion for positioning and locking the case main body 53 and the finisher 54, is formed in a straight line along the front-rear direction on the outer peripheral surface of the housing portion 58. In addition, a claw portion 58b is formed so as to protrude inside the locking recess 58a. These locking recesses 58a are spaced from each other at substantially equal intervals in the circumferential direction of the case body 41.

  Hereinafter, the circumferential direction of the case body 41 refers to a direction along an arc centering on the central axis on a plane orthogonal to the central axis of the case body 41.

  The upper case main body 51 and the lower case main body 52 are configured to divide the main body portion 57 and the housing portion 58 into two parts, for example, approximately vertically. That is, the upper case main body 51 includes a semi-cylindrical upper main body portion 51a as one main body portion constituting the upper half of the main body portion 57 and one hemispherical housing constituting the upper half of the housing portion 58. The lower case main body 52 has a semi-cylindrical lower main body as the other main body component constituting the lower half of the main body 57. The portion 52a and a hemispherical lower accommodating portion 52b as the other accommodating portion constituting the lower half of the accommodating portion 58 are integrally provided in the front-rear direction. Further, for example, on both sides of the upper main body 51a and on both sides of the lower main body 52a, side locking arm portions 51c as locking fixing portions for locking and fixing the upper main body 51a and the lower main body 52a to each other, 51c and side locking recesses 52c, 52c are formed. Each side locking arm 51c is a portion inserted into each side locking recess 52c, and protrudes linearly downward from the lower ends on both sides of the upper body 51a. A locking hole 51d is formed on the distal end side of the arm 51c. Each side locking recess 52c is linearly formed downward from the upper ends on both sides of the lower main body 52a, and the side locking recess 52c has a locking hole 51d inside. A locking claw portion 52d to be inserted and locked is formed to protrude.

  The finisher 54 forms a part of the design surface at the mounting position of the wind direction adjusting device 10, and has a disk shape in which a vent 64, which is a circular outlet, is opened in the center. Further, a locking arm portion 54a inserted into the locking recess 58a of the case body 53 is formed to protrude forward around the vent hole 64 on the front side of the finisher 54. These locking arm portions 54a A claw hole portion 54b into which the claw portion 58b is inserted and engaged is opened on the distal end side.

  The case main body 53 and the finisher 54 are locked and fixed to each other, whereby the rear ends of the guide groove portions 61 and 62 are closed by the finisher 54, and the spacers 42 are arranged in the circumferential direction of the case body 41 (ventilation port 64). Guide recesses 66 and 67 (one and the other) that are movably guided are formed, and a guide portion 68 is constituted by these guide recesses 66 and 67. The guide recesses 66 and 67 are formed in a circular arc shape (a shape along a part of a circular shape) along the housing portion 58 of the case main body 53 and in a longitudinal shape in the front-rear direction. That is, the guide recesses 66 and 67 (guide portions 68) are formed along the direction in which the wind passes through the case body 41, that is, along the axial direction of the case body 41, and the fins are guided by guiding the spacers 42. It is configured to set an elevation angle of 43.

  Each spacer 42 has a flat spacer main body 42a as a movable piece main body that abuts on the fin 43 side, and protrudes perpendicularly to the spacer main body 42a so that the tip side is inserted into the guide recesses 66 and 67. A flat plate-like inserted portion 42b is integrally provided. That is, the spacers 42 are arranged at positions where the guide portion 68 is opposed to each other. Further, on the side of the spacer main body 42a opposite to the insertion portion 42b opposite to the fin 43, there is a round hole bearing concave portion 42c as a bearing portion for rotatably supporting the fin 43 in the left-right direction. Is formed.

  The fins 43 are also referred to as housings or louvers, and control the wind direction and the amount of air blown out from the wind direction adjusting device 10, for example, a plurality of, for example, three blade portions 43a formed in a cylindrical shape having different diameters. , 43b, 43c are concentrically (coaxially) integrally formed, and flat blade portions 43d, 43e formed in an arc shape in a side view connecting these blade portions 43a to 43c are integrally formed in a cross shape. Have. The blade portions 43d and 43e intersect each other at right angles at the central axis positions of the blade portions 43a to 43c. Therefore, a vent hole 43f penetrating in the front-rear direction is formed between each of the blade portions 43a to 43e, and the central axis of the fin 43 is a wind axis that is the direction of the wind controlled by the fin 43. It has become. Further, shaft portions 43g and 43g as support shafts are projected from the blade portion 43a.

  These shaft portions 43g are formed in a cylindrical shape, and are inserted into the bearing concave portions 42c of the spacer 42.

  When assembling the wind direction adjusting device 10, first, the shaft portions 43g, 43g of the fins 43 are inserted into the bearing recesses 42c, 42c of the spacers 42, 42, and the fins 43 to which the spacers 42, 42 are attached are The case body 51 and the lower case body 52 are sandwiched from above and below. At this time, each side locking arm portion 51c of the upper case body 51 is moved to the lower case body 52 while aligning the leading ends of the inserted portions 42b, 42b of the spacers 42 so as to be inserted into the guide groove portions 61, 62. The upper case main body 51 and the lower case main body 52 are inserted into the holding hole 58 by being inserted along the respective side locking recesses 52c and pushed into the locking holes 51d to the positions where the locking claws 52d are engaged. The fins 43 are held and fixed to each other.

  Then, a finisher 54 is inserted into the case main body 53 containing the fins 43 from the rear, and the respective locking arm portions 54a are inserted into the respective locking concave portions 58a while being aligned with the respective locking concave portions 58a. The case main body 53 and the finisher 54 are locked and fixed to each other by being pushed to the position where the claw portion 58b is engaged. As a result, the wind direction adjusting device 10 is completed in which the fins 43 can be rotated in the vertical direction along the guide recesses 66 and 67 through the spacers 42 and the fins 43 can be rotated with respect to the spacers 42. .

  And the wind direction adjusting apparatus 10 installed in the to-be-installed part of the interior member of a motor vehicle WHEREIN: When the fin 43 is made into the neutral (neutral) position, as shown in FIG. The wind axis is parallel to the central axis. At this time, wind flows from the vent 64 toward the front of the occupant.

  When the left and right upper sides of the fins 43 are pushed forward from the neutral position, the upper spacer 42 moves forward along one guide recess 66 as shown in FIG. 13B. Thus, the lower spacer 42 moves rearward along the other guide recess 67 so that the distance between the upper spacer 42 and the lower spacer 42 is constant. In other words, the fin 43 has the accommodating portion 58 when the upper shaft portion 43g moves relatively forward and the lower shaft portion 43g moves relatively backward, that is, moves in opposite directions. , The wind axis intersects the central axis of the case body 41, and the wind flows upward from the vent 64 to the occupant. The upper shaft portion 43g can be rotated to a position where it comes into contact with one stopper surface 61a (a position where the lower shaft portion 43g comes into contact with the front surface of the finisher 54). The inclination in the direction is the maximum.

  Similarly, when the lower side of the fin 43 is pushed forward from the neutral position, the lower spacer 42 moves forward along the other guide recess 67 as shown in FIG. On the other hand, the upper spacer 42 moves rearward along one guide recess 66 so that the distance between the upper spacer 42 and the lower spacer 42 is constant. That is, the fin 43 has the accommodating portion 58 when the lower shaft portion 43g moves relatively forward and the upper shaft portion 43g moves relatively backward, that is, moves in opposite directions. The wind axis intersects with the central axis of the case body 41, and the wind flows downward from the occupant 64. The lower shaft portion 43g can be rotated to a position where it contacts the other stopper surface 62a (a position where the upper shaft portion 43g contacts the front surface of the finisher 54). The inclination in the direction is the maximum.

  Note that the fin 43 not only pushes the upper or lower side in the left-right direction, but also rotates, for example, to have a left-right direction component, in other words, pushes the upper left, lower left, upper right, lower right, etc. Thus, not only the spacers 42 move along the guide recesses 66 and 67, but also the fins 43 rotate with respect to the spacers 42 and 42, so that the direction of the air blown out from the vent 64 can be freely adjusted in three dimensions. Can be variable.

  As described above, according to the present embodiment, the fins 43 are opposed to the spacers 42 and 42 that are movably guided along the guide recesses 66 and 67 of the guide portion 68 formed in the arc shape of the case body 41. Are movably supported in a direction different from the moving direction of the spacers 42, so that the fins 43 are guided only by the spacers 42 along the guide recesses 66 and 67 of the guide portion 68 (front-rear direction) and with respect to this direction. It can be movably supported in different directions (left and right directions). Therefore, compared with the configuration including parts that support the fins movably corresponding to each of these directions, the number of parts can be reduced, the assembly man-hours can be reduced, the workability of assembly, the mold production cost, etc. The total cost can be reduced.

  The guide recesses 66 and 67 of the guide portion 68 guide the spacers 42 and 42 so as to be movable along the axial direction (front-rear direction) in which the wind of the case body 11 passes. The recesses 42c pivotally support the shafts 43g of the fins 43 in a direction intersecting (orthogonal) with respect to the axial direction of the case body 11 (left and right direction), so that the direction of the fins 43 is changed to the left and right directions. It can be managed with two axes intersecting (orthogonal) with each other, and the user can change the wind direction only by pushing the fin 43 in the desired wind direction. . That is, in this embodiment, when the wind direction is changed, it is only necessary to press the fin 43, and when the wind direction is directed from the left and right direction to the up and down direction, for example, two actions of twisting the fin and adjusting the angle are not necessary. A good feeling of use and operation can be obtained.

  In addition, the guide recesses of the guide portion 68 are supported by pivotally supporting the shaft portions 43g of the fins 43 on the bearing recess portions 42c of the spacers 42 disposed in the guide recess portions 66 and 67 facing each other of the guide portion 68, respectively. By appropriately setting the frictional force between 66, 67 and each spacer 12, that is, the sliding resistance (matching), it is possible to manage the operation torque for turning the fin 43 in the vertical direction. By appropriately setting the frictional force of each spacer 42 with the bearing recess 42c, that is, the sliding resistance (matching), the operation torque for rotating the fin 43 in the left-right direction can be managed, so that the operation torque of the fin 43 can be reliably and Easy to manage. In other words, the operation torque of the fins 43 can be reliably managed by managing the manufacturing accuracy of each spacer 42.

  In the fourth embodiment, as in the fifth embodiment shown in FIG. 14, instead of the spacer 42, for example, a synthetic resin such as silicone rubber having good slidability (silicone rubber) is used. Using a movable piece 71 that is formed separately from the fin 43 by a member of the above, or a two-color molded shaft 43g of the fin 43, similarly to the spacer 42, the guide is movably guided along the guide recesses 66 and 67 of the guide 68. It is good also as composition to do.

  Further, as in the sixth embodiment shown in FIG. 15, the case body 41 may be integrally formed with, for example, the lower main body portion 52a and the finisher 54. Although not shown, the upper main body portion 51a and the finisher 54 are integrally formed. 54 may be formed integrally.

  Further, as in the seventh embodiment shown in FIG. 16, the case body 41 has, for example, the maximum diameter position of the housing portion 58, in other words, the center position in the front-rear direction of the housing portion 58 (the longitudinal length of the guide recesses 66 and 67). You may divide into the front and back by setting the center position of the direction) as a boundary. That is, the case body 41 may be configured by, for example, the front case body 73 and the rear case body 74 that are one and the other case constituent bodies. In this case, for example, the front case body 73 integrally includes a main body portion 57 and a front housing portion 76 that is one housing portion constituting the front side of the housing portion 58, and the rear case body 74 is composed of the housing portion. The rear housing portion 77, which is the other housing portion constituting the rear side of 58, and the finisher 54 are integrally provided, and a locking arm portion 54a having a claw hole portion 54b is provided on the rear housing portion 77. By projecting forward from the outer peripheral portion and forming a locking recess 58a having a claw portion 58b in the outer peripheral portion of the front housing portion 76 along the front-rear direction, the same action as in the third embodiment described above There is an effect.

  The sixth and seventh embodiments may be applied to the fifth embodiment described above.

  In the third to seventh embodiments, one shaft portion 43g may be spherical (pivot shape) as in the eighth embodiment shown in FIG.

  Further, the wind direction adjusting device 10 is not limited to a so-called round type, and instead of the fins 13 and 43, for example, as in the ninth embodiment shown in FIGS. 18 (a) to 18 (c), A configuration including fins 81 as a box-type wind direction control body may be employed.

  That is, the fin 81 is, for example, a quadrangular plate shape that couples the blade portions 81a, 81b, 81c, which are rectangular plate-like rectifying portions that form a pair spaced apart substantially in parallel, and the blade portions 81a to 81c at the upper and lower positions. The connecting portions 81d and 81e are formed in a rectangular tube shape. Therefore, air holes 81f and 81g are formed between the blade portions 81a, 81b, and 81c, and the direction along each blade portion 81a to 81c is the wind axis that is the direction of the wind controlled by the fin 81. It has become. Furthermore, shaft portions 81h and 81i as support shafts (one and the other) protrude from the coupling portions 81d and 81e, respectively.

  One shaft portion 81h is formed in a spherical shape on the tip side. The other shaft portion 81i is formed in a cylindrical shape. The first and second shaft portions 81h and 81i are movably supported by spacers 83 and 84 as movable pieces (one and the other).

  One spacer 83 is provided with a bearing recess 83a as a spherical bearing at the center, and supports one shaft 81h so that it can rotate 360 °.

  The other spacer 84 is provided with a through hole 84a as a bearing portion formed in a long hole shape along the front-rear direction, the other shaft portion 81i can be rotated in the left-right direction, and in the front-rear direction. It is pivotally supported.

  The one spacer 83 and the other spacer 84 are movable in the left-right direction by guide recesses 86, 87 formed in an arc shape along the left-right direction at the upper and lower portions of the case body 11. Guided. These guide recesses 86 and 87 constitute a guide portion 88.

  As a result, by rotating the fin 81 in the left-right direction, the spacers 83, 84 move in the left-right direction along the guide recesses 86, 87 of the guide portion 88, and the fin 81 moves relative to the spacers 83, 84. By rotating in the left-right direction, the fin 81 is in a position where the blade portions 81a to 81c intersect the center axis of the case body 11, that is, the wind axis, and the wind is blown out along the direction of the wind axis.

  Further, by rotating the fin 81 in the vertical direction, the fin 81 is rotated in the vertical direction around the one shaft portion 81h, thereby setting the elevation angle of the wind axis.

  Therefore, by appropriately combining these operations, the direction of the blown-out wind can be freely changed in three dimensions.

  Thus, according to the present embodiment, even with the box-shaped fin 81, the spacers 83, 84 are movable relative to the spacers 83, 84 that are movable along the guide recesses 86, 87 of the guide portion. By supporting the fin 81 movably in a direction intersecting with the moving direction along the guide recesses 86 and 87 of the guide portion 88, the same effects as those of the above-described embodiments can be obtained.

  In each of the above embodiments, the guide portions 35, 68, and 88 may be projected in a rail shape instead of a groove shape.

  The wind direction adjusting device 10 is not limited to a vehicle, and can be used for adjusting the wind direction of an arbitrary air conditioner or the like.

  The present invention can be suitably used, for example, as a wind direction adjusting device for air conditioning of automobiles.
