The horizontal fins 15 are provided at the front end portion of the retainer 11 to which the bezel 13 is attached, and are arranged inside the air outlet 13A. In the following description, as shown in FIGS. 1 to 5, with the front end position and the rear end position of the horizontal fins 15 aligned in the vertical direction (hereinafter, sometimes referred to as a neutral state) as a reference direction The horizontal fin 15 will be described.

FIG. 6 shows an exploded perspective view of members arranged in the register 10. As shown in FIG. 6, in the register 10, in addition to the plurality of horizontal fins 15, an operation knob 17, a plurality of vertical fins 19 and the like are arranged. Of the three horizontal fins 15, the operation knob 17 is attached to the horizontal fin 15 arranged at the center in the vertical direction. In the following description, the horizontal fin 15 to which the operation knob 17 is attached as shown in FIG. 6 will be referred to as a central horizontal fin 15A when distinguished from other horizontal fins 15. Further, when a plurality of horizontal fins 15 are collectively referred to, they will be referred to as horizontal fins 15 without the alphabet.

As shown in FIG. 6, each of the plurality of horizontal fins 15 has a substantially rectangular plate shape that is long in the left-right direction. The horizontal fin 15 has a predetermined thickness in the up-down direction, and has a plate shape extending in the left-right direction while having a substantially constant width in the front-rear direction. The operation knob 17 is attached to a substantially central portion of the central horizontal fin 15A in the left-right direction. The operation knob 17 includes a first operation knob portion 17A arranged on the front side and a second operation knob portion 17B arranged on the rear side. The first and second

operation knob portions

17A and 17B are combined with each other to form the operation knob 17 having the fin insertion hole 17C. The first operation knob portion 17A is fixed to the second operation knob portion 17B in a state where the claw portion 17D is fitted in the second operation knob portion 17B. The first and second

operation knob portions

17A and 17B are attached to the central horizontal fin 15A in a state where the central horizontal fin 15A is inserted into the fin insertion hole 17C and are slidable in the left and right directions.

A plurality of (four in the illustrated example) vertical fins 19 are arranged on the upstream side (rear side) of the plurality of horizontal fins 15. The vertical fins 19 are rotatably held by an upper bearing member 21 about a rotary shaft 19A formed on an end face in the upward direction. Further, the vertical fin 19 is rotatably held by a lower bearing member 22 on a rotary shaft 19A formed on the lower end surface. The upper bearing member 21 and the lower bearing member 22 are fixed to the retainer 11. The plurality of vertical fins 19 are rotatable in the left-right direction by holding the rotating shaft 19A on the upper bearing member 21 and the lower bearing member 22.

The vertical fin rod shafts 19C formed on each of the plurality of vertical fins 19 are connected to each other by a vertical fin link rod 23. The plurality of vertical fins 19 are interlocked with each other by a vertical fin link rod 23 to rotate in the left-right direction. A gear 19B is formed on the front side of one vertical fin 19 among the plurality of vertical fins 19. The gear 19B meshes with a gear 17E formed on the rear side (upstream side) of the operation knob 17. As a result, when the operation knob 17 is slid in the left-right direction, the driving force is transmitted by the

gears

19B and 17E, and the plurality of vertical fins 19 rotate in accordance with the moving direction of the operation knob 17. By rotating the plurality of vertical fins 19 left and right, the blowing direction of the air blown out from the air outlet 13A can be changed to the left and right direction.

(About horizontal fin 15)
Further, the plurality of horizontal fins 15 have substantially the same shape. Therefore, in the following description, the central horizontal fin 15A will be mainly described, and the description of the other horizontal fins 15 will be appropriately omitted. As shown in FIGS. 7 to 12, the central horizontal fin 15A includes first and second

rotating shafts

31 and 32. Each of the first and second

rotating shafts

31 and 32 is a downstream end of the central horizontal fin 15A, and is provided on each of both sides in the left-right direction. The first rotating shaft 31 projects from the right end surface 33 of the central horizontal fin 15A to the outside (right side) in the left-right direction, and has a substantially columnar shape. The second rotating shaft 32 protrudes outward (left side) from the left end face 34 of the central horizontal fin 15A and has a substantially columnar shape. The first and

second rotation shafts

31 and 32 form a rotation shaft along the left-right direction, that is, the longitudinal direction of the central horizontal fin 15A.

As shown in FIGS. 13 to 16, the first rotation shafts 31 of the plurality of horizontal fins 15 are rotatably held by a right side support member 37 arranged on the right side of the horizontal fins 15. The right support member 37 has a predetermined thickness in the left-right direction, has a shape that is long in the up-down direction, and has a shape that is uneven in the left-right direction. As shown in FIG. 17, the right support member 37 is formed with three first through holes 37A corresponding to the position of the first rotation shaft 31 of the horizontal fin 15. The three first through holes 37A penetrate the right side support member 37 in the left-right direction. The cross-sectional shape of the first through hole 37A is circular.

As shown in FIGS. 7 to 12, the tip end portion (right end portion) of the first rotating shaft 31 is formed with a tip engaging portion 31A having a thicker shaft diameter. The tip end engaging portion 31A is thicker than the tip end engaging portion 31A on the base end side (left side), and engages with the first through hole 37A by being inserted into the first through hole 37A. As a result, the first rotating shaft 31 is prevented from coming off from the first through hole 37A, and is rotatably held with respect to the right support member 37.

Further, as shown in FIGS. 7 to 16, a connecting portion 39 is formed on the first rotating shaft 31. The connecting portion 39 is formed on the base end side (left side) of the position where the right side support member 37 is attached to the first rotating shaft 31. The connecting portion 39 has a plate shape extending in a direction orthogonal to the axial direction (left-right direction) of the first rotating shaft 31. The connecting portion 39 has a substantially triangular shape in which the width in the up-down direction gradually increases from the first rotating shaft 31 toward the upstream side (see FIG. 11 ). A rod shaft 41 is formed at the rear end (upstream side) of the connecting portion 39. The rod shaft 41 projects in a direction parallel to the axial direction (left-right direction) of the first rotating shaft 31 and outwardly (rightward) from the right end surface 33 of the horizontal fin 15, and has a substantially columnar shape. The rod shaft 41 is an end portion on the upstream side (rear side) of the connecting portion 39 having a substantially triangular shape, and is formed on the end portion on the lower side. Therefore, the rod shaft 41 of the present embodiment is arranged at a position (offset position) deviated from the first rotation shaft 31 in the vertical direction and the front-back direction. As a result, it is possible to facilitate the drawing operation of the mold forming the first rotating shaft 31 and the rod shaft 41.

The rod shafts 41 of the plurality of horizontal fins 15 are connected to each other by a link rod 43 (see FIG. 13). As with the first rotating shaft 31, a tip engaging portion 41A is formed at the tip of the rod shaft 41. As shown in FIG. 18, the link rod 43 has a thin plate shape elongated in the vertical direction. The link rod 43 is formed with three rod holes 43A according to the position of the rod shaft 41. By inserting the tip engaging portion 41A into the rod hole 43A, the rod shaft 41 is prevented from coming off from the rod hole 43A, and is rotatably held with respect to the link rod 43. As a result, when one horizontal fin 15 among the plurality of horizontal fins 15 rotates, the other horizontal fins 15 rotate together.

As shown in FIGS. 14 and 15, an engaging portion 37B is formed on the right side support member 37. The engagement portion 37B is formed on the inner peripheral surface 37C of the right support member 37 that faces the right end surface 33 of the horizontal fin 15 in the left-right direction. Three engagement portions 37B are formed on the inner peripheral surface 37C. Each of the three engaging portions 37B is formed at a position below the connecting portion 39 of each horizontal fin 15. The engagement portion 37B is formed so as to project inward (left side) from the inner peripheral surface 37C, and is formed at a position where it abuts on the coupling portion 39. The connecting portion 39 rotates in the vertical direction in conjunction with rotating the horizontal fin 15 in the vertical direction. Each of the three connecting portions 39 engages with each of the engaging portions 37B from the upper side when rotating downward from the neutral state to a certain range. Further, when the connecting portions 39 formed on the central horizontal fin 15A and the lowermost horizontal fin 15 rotate upward from the neutral state to a certain range, the connecting portions 39 engage with the engaging portions 37B located above from the lower side. To meet. The engaging portion 37B engages with the connecting portion 39 to regulate the vertical rotation of the horizontal fin 15. As a result, the horizontal fin 15 has its rotation range limited to a certain range.

Further, as shown in FIGS. 13 to 16, the second rotation shafts 32 of the plurality of horizontal fins 15 are rotatably held by the left side support member 45 arranged on the left side of the horizontal fins 15. The left support member 45 has a predetermined thickness in the left-right direction, has a shape that is long in the up-down direction, and has a shape that is uneven in the left-right direction. Similar to the right side support member 37, the left side support member 45 is formed with three second through holes 45A corresponding to the position of the second rotation shaft 32 of the horizontal fin 15. The three second through holes 45A are circular holes that penetrate the left support member 45 in the left-right direction. The second rotation shaft 32 is inserted into the second through hole 45A and is rotatably held by the left support member 45.

Also, the left support member 45 is formed with an insertion portion 45B. The insertion portion 45B is formed on the inner peripheral surface 45C of the left support member 45 that faces the left end surface 34 (see FIG. 12) of the horizontal fin 15 in the left-right direction. The insertion portion 45B is formed by recessing the inner peripheral surface 45C to the left. The portion on the rear side (upstream side) of the insertion portion 45B is open. A regulating rod 47 is formed on the rear side of the left end of the central horizontal fin 15A (see FIGS. 7 to 10). The restriction rod 47 projects leftward from a portion projecting upward from the upper surface of the central horizontal fin 15A, and has a columnar shape.

The insertion portion 45B is formed to match the position of the regulation rod 47 of the central horizontal fin 15A, and the regulation rod 47 is inserted therein. The front surface of the insertion portion 45B has an arc shape according to the trajectory of rotation of the restriction rod 47. When the central horizontal fin 15A rotates upward or downward to a certain range, the restriction rod 47 collides with the inner wall of the insertion portion 45B and is restricted from moving. As a result, the horizontal fin 15 has its rotation range limited to a certain range. The rotation range regulated by the regulation rod 47 and the insertion portion 45B coincides with the range regulated by the engagement portion 37B and the coupling portion 39 described above. Therefore, the rotation range of the plurality of horizontal fins 15 is limited by both the right engaging portion 37B and the left regulating rod 47.

The central horizontal fin 15A is rotated in the vertical direction by operating the operation knob 17. Further, the other horizontal fins 15 rotate in the up-down direction in association with the central horizontal fin 15A by the link rod 43. As a result, the plurality of horizontal fins 15 rotate in the vertical direction in conjunction with each other, and change the blowing direction of the air blown from the air outlet 13A to the vertical direction.

As shown in FIGS. 19 to 21, a housing portion 51 is formed on the right side portion of the front end portion of the retainer 11. The accommodating portion 51 has a substantially box shape with an open front surface. The housing portion 51 has a substantially constant width in the left-right direction, and has a box shape that is long in the up-down direction. FIG. 22 shows an enlarged view of the region 53 of FIG. As shown in FIG. 22, the right side support member 37 and the link rod 43 provided on the right side of the horizontal fin 15 are housed in the housing portion 51.

As shown in FIG. 13, two engaging claws 37D are formed on the outer peripheral surface of the right support member 37. As shown in FIGS. 19 to 21, two engagement holes 52A are formed in the right side wall 52 of the accommodation portion 51 in accordance with the position of the engagement claw 37D. As shown in FIG. 23, the right support member 37 is fixed to the right side wall 52 (accommodation portion 51) by engaging the engagement claw 37D with the engagement hole 52A. The retainer 11 rotatably holds the first rotation shaft 31 of the horizontal fin 15 via the right side support member 37. A regulation plate 37E is formed on the outer peripheral surface of the right support member 37 (see FIG. 13). The regulation plate 37E is formed at a position slightly lower than the central portion of the right support member 37 in the vertical direction, is thin in the vertical direction, and has a plate shape extending in the front-rear direction. As shown in FIG. 23, the right support member 37 is fixed to the retainer 11 with the restriction plate 37E inserted from the front into the insertion hole 52B formed in the right side wall 52. As a result, the right support member 37 can suppress the positional deviation with respect to the retainer 11, and can suppress the rattling of the first rotating shaft 31.

Similarly, as shown in FIG. 14, two engaging claws 45D are formed on the outer peripheral surface of the left support member 45. Two retainer holes 11C are formed in the left side wall on the front side of the retainer 11 in accordance with the positions of the engaging claws 45D (see FIG. 19). As shown in FIG. 24, the left support member 45 is fixed to the retainer 11 by engaging the engagement claw 45D with the engagement hole 11C. The retainer 11 rotatably holds the second rotation shaft 32 of the horizontal fin 15 via the left support member 45. A regulation plate 45F is formed on the outer peripheral surface of the left support member 45 (see FIG. 14). The regulation plate 45F is formed at a position slightly above the central portion of the left side support member 45 in the vertical direction, is thin in the vertical direction, and has a plate shape extending in the front-rear direction. An insertion recess 11F is provided on the left side wall on the front side of the retainer 11 in accordance with the position of the restriction plate 45F (see FIG. 19). The left support member 45 is fixed to the retainer 11 with the restriction plate 45F inserted into the insertion recess 11F from the front. The left support member 45 is attached to the retainer 11 with the two insertion plates 45E (see FIG. 14) provided on the rear side inserted into the insertion holes 11D (see FIG. 19) formed in the retainer 11 from the front. Fixed against. As a result, the left support member 45 can be prevented from being displaced with respect to the retainer 11 and can prevent rattling of the second rotating shaft 32.

As shown in FIG. 22, the right support member 37 is fixed to the right side wall 52 to hold the first rotating shaft 31, the connecting portion 39, the rod shaft 41, and the link rod 43 in the housing portion 51. doing. The link rod 43 is arranged at substantially the same position as the right support member 37 in the left-right direction, and is arranged at a position along the front-rear direction. The connecting portion 39 is arranged inside (left side) of the positions of the link rod 43, the right support member 37, and the tip engaging portion 31A. Therefore, the right support member 37 of the present embodiment is attached to the first rotation shaft 31 outside the position of the connecting portion 39 in the direction from the right end surface 33 of the horizontal fin 15 to the outside (right side). ..

The inner wall of the right side wall 52 is formed with a shaft retreat portion 52C that is recessed according to the position of the tip engaging portion 31A. Since the right side wall 52 is formed with the shaft retreat portion 52C, it is possible to avoid contact with the tip end engaging portion 31A. Thereby, the 1st rotating shaft 31 can be rotated stably.

Further, as shown in FIGS. 19 to 21, the left side wall 55 of the accommodating portion 51 is formed with three recesses 55A corresponding to the position of the first rotating shaft 31. When viewed from the left and right, the recess 55A has a shape in which the front side is opened and the left side wall 55 is cut out rearward. The recess 55A has a substantially constant width in the vertical direction, and the rear end portion is formed in an arc shape.

As shown in FIG. 22, the base end portion 31B of the first rotating shaft 31 is housed in the recess 55A. The front end of the first rotation shaft 31 is held by the right side support member 37 with a gap provided between the first rotation shaft 31 and the recess 55A in the front-rear direction and the up-down direction. Therefore, the horizontal fins 15 of the present embodiment are not in direct contact with the retainer 11, but are indirectly held by the retainer 11 via the right side support member 37.

(About 2-color molding and in-mold assembly)
The register 10 of the present embodiment is formed by so-called in-mold assembly of two-color molding, which is a unit in which a plurality of members shown in FIGS. 13 to 16 are combined. Assembling in the mold here is a molding method in which a plurality of members are formed by the same mold and then the assembly is performed in the same mold. In the register 10 of this embodiment, the six members of the three horizontal fins 15, the right side support member 37, the link rod 43, and the left side support member 45 shown in FIGS. It can be sub-assembled as a member.

Describing in detail, for example, the three horizontal fins 15 are molded from synthetic resin such as glass-containing polybutylene terephthalate (PBT). The right side support member 37, the left side support member 45, and the link rod 43 are made of synthetic resin such as elastomer. The material of the horizontal fin 15, the right support member 37, etc. is not limited to the above-mentioned resin, but may be ABS resin, for example.

FIG. 25 shows a molding state of the right support member 37 and the link rod 43 in the mold. As shown in FIG. 25, for example, the elastomer injected from the nozzle is poured into the mold through one gate of the mold. The right support member 37 and the link rod 43 are formed in a state of being connected by the gate mark 57. The right support member 37 and the link rod 43 are separated by shifting the mold. Further, the horizontal fin 15 formed by PBT injected from another gate is moved to insert the first rotation shaft 31 into the first through hole 37A of the right support member 37. Further, the rod shaft 41 is inserted into the rod hole 43A of the link rod 43. Further, the second rotating shaft 32 is inserted into the second through hole 45A of the left support member 45. Thereby, the right side support member 37, the link rod 43, and the left side support member 45 are attached, and a member in which the three horizontal fins 15 are sub-assembled can be molded.

As described above, in the register 10 of the present embodiment, this sub-assembled member (hereinafter sometimes referred to as a unit member) can be fitted from the front surface of the retainer 11. The right support member 37 and the left support member 45 are attached to the retainer 11 while the right support member 37 and the link rod 43 are housed in the housing portion 51.

Here, for example, in the structure in which the first rotating shaft 31 is fitted into the bearing portion provided in the retainer 11, the retainer 11 is larger than the horizontal fins 15, so that the in-mold assembling in one mold is not possible. It will be difficult. Further, the work of attaching each of the plurality of first rotary shafts 31 to the retainer 11 and the work of connecting the horizontal fins 15 with the link rods 43 occur, and the work content becomes complicated. On the other hand, in the structure of the present embodiment, the unit member that is automatically assembled into a sub-assembly is attached to the retainer 11, so that the assembling property of the horizontal fin 15 to the retainer 11 is dramatically improved. You can Further, it is possible to reduce the manufacturing cost.

Incidentally, the horizontal fins 15 are an example of fins. The first rotation shaft 31 is an example of a rotation shaft. The right end surface 33 is an example of an end surface. The right side support member 37 is an example of a support member. The first through hole 37A is an example of a through hole.

According to the above-mentioned 1st Embodiment, there exists the following effect.
(1) The register 10 of the present embodiment includes a retainer 11 in which an air passage 11A and a housing portion 51 are formed, a right support member 37 housed in the housing portion 51 and held by the housing portion 51, and a plate shape. A plurality of horizontal fins 15 that are formed on the right side support member 37 to hold the first rotation shaft 31 and rotate in the ventilation passage 11A, and the rod shafts 41 provided on each of the plurality of horizontal fins 15 are connected to each other. And a link rod 43. The link rod 43 is housed in the housing portion 51.

According to this, the plurality of horizontal fins 15 rotate in conjunction with each other by connecting the rod shaft 41 with the link rod 43. The link rod 43 is housed in the housing portion 51 formed in the retainer 11. As a result, the ventilation resistance generated by the link rod 43 can be eliminated by not disposing the link rod 43 in the ventilation passage 11A. In addition, the right support member 37 and the link rod 43 are arranged in the housing portion 51 and hidden in another place from the ventilation passage 11A, thereby improving the designability when the register 10 is viewed from the front (driver's side). It becomes possible.

Further, the plurality of horizontal fins 15 are held by the right side support member 37. The retainer 11 can indirectly hold the horizontal fins 15 via the right side support member 37. For example, the plurality of horizontal fins 15, the right side support member 37, the left side support member 45, and the link rod 43 can be automatically assembled in the mold after injection molding by so-called in-mold assembly. The plurality of horizontal fins 15, the right side support member 37, the left side support member 45, and the link rod 43 can be combined into one unit member to form a sub-assembly. As a result, the assemblability of the horizontal fin 15 and the like to the retainer 11 can be improved, and the manufacturing cost can be reduced.

(2) Further, the right support member 37 is formed with a first through hole 37A into which the first rotation shaft 31 is inserted and which is rotatably held. For example, when the retainer 11 directly holds the first rotating shaft 31 and thus the bearing portion is formed by cutting out a part of the retainer 11, the first rotating shaft 31 inserted in the bearing portion may be replaced by the other member on the front side. It becomes necessary to hold it from above. In such a structure, depending on the mounting accuracy of the bearing portion and other members, the first rotary shaft 31 to be held may rattle, and it becomes difficult to manage the load applied to the first rotary shaft 31. On the other hand, in the register 10 of the present embodiment, the first rotating shaft 31 of the fin is held by the first through hole 37A of the right support member 37, so that the first rotating shaft 31 can be held stably, and The load applied to the rotary shaft 31 can be easily managed.

(3) Further, the first rotating shaft 31 is formed so as to project outward from the right end surface 33 of the horizontal fin 15, and the connecting portion 39 extending in the direction orthogonal to the axial direction is formed. The rod shaft 41 is formed at the tip of the connecting portion 39, in a direction parallel to the axial direction (left-right direction) of the first rotating shaft 31, and in a direction from the right end surface 33 of the horizontal fin 15 to the outside (right side). It is formed to project.

According to this, the right side support member 37 can be assembled to the first rotating shaft 31 from the outside (right side). Further, the link rod 43 can be assembled to the rod shaft 41 from the outside (right side). Thereby, the assembling property can be improved. Further, the link rod 43 and the right side support member 37 can be arranged close to each other, and for example, the two members can be molded together by the synthetic resin injected from one gate.

(4) Further, the right support member 37 is attached to the first rotary shaft 31 at a position outside (right side) of the position of the connecting portion 39 in the direction outward from the right end surface 33 of the horizontal fin 15. (See FIG. 22). According to this, the right support member 37 can be disposed outside the connecting portion 39 and attached to the first rotating shaft 31.

(5) Further, the right support member 37 has an engagement portion 37B formed on the inner peripheral surface 37C that faces the right end surface 33 of the horizontal fin 15. The engaging portion 37B engages with the connecting portion 39 to limit the rotation range of the plurality of horizontal fins 15 to a certain range. According to this, by engaging the engaging portion 37B of the right side support member 37 and the connecting portion 39, it is possible to limit the rotation range of the plurality of horizontal fins 15 to a certain range. It is possible to prevent a collision between the plurality of horizontal fins 15 and the retainer 11.

(6) Further, the accommodating portion 51 has a concave portion 55A formed so as to match the position of the first rotating shaft 31, and accommodates the first rotating shaft 31 in the concave portion 55A. The first rotation shaft 31 is held by the right support member 37 with a gap provided between the first rotation shaft 31 and the recess 55A. According to this, the retainer 11 accommodates the first rotating shaft 31 in the recess 55A formed by recessing a part of the accommodating portion 51. Since the rotating shaft 19A is arranged in a state of being separated from the recess 55A, the generation of frictional resistance with the retainer 11 is suppressed.

(Second embodiment)
Next, a second embodiment of the present disclosure will be described. The register 10 of the first embodiment described above includes the left side support member 45. The retainer 11 indirectly holds the second rotation shaft 32 of the horizontal fin 15 via the left support member 45. On the other hand, as shown in FIGS. 26 and 27, the register 10 of the second embodiment does not include the left side support member 45 and has a structure in which the retainer 11 directly holds the second rotating shaft 32. ..

In detail, the operation knob 17 of the first embodiment described above is configured by combining two members, a first operation knob portion 17A and a second operation knob portion 17B (see FIG. 6). On the other hand, the operation knob 17 of the second embodiment is integrally formed by one member. As shown in FIG. 26, the operation knob 17 has a fin insertion hole 17C into which the central horizontal fin 15A is inserted and is configured as one member. Further, the regulating rod 47 (see FIG. 7) is not formed on the left end portion of the central horizontal fin 15A, and has a shape in which the unevenness of the upper surface is eliminated. The central horizontal fin 15A is inserted from the right side of the operation knob 17, and the operation knob 17 is attached.

As shown in FIG. 27, the left side support member 45 is not arranged on the left side of the horizontal fin 15. The retainer 11 is formed with three bearing holes 11E into which the second rotary shafts 32 of the three horizontal fins 15 are inserted. Three bearing holes 11E are formed at the front end portion of the left side wall of the retainer 11 and are aligned with the position of the second rotating shaft 32.

In the register 10 of the second embodiment, for example, the three horizontal fins 15, the right side support member 37, and the link rod 43 are sub-assembled into a unit member by in-mold assembly of two-color molding. Next, the central horizontal fin 15A is inserted into the operation knob 17, and the operation knob 17 is attached to the unit member (see FIG. 26). Then, as shown in FIG. 27, by inserting the three second rotating shafts 32 into the bearing holes 11E and fitting the right side support member 37 into the housing portion 51, the unit member is retained in the retainer 11. The horizontal fins 15 can be attached to the retainer 11. With such a configuration, it is possible to improve the assemblability of the horizontal fin 15 to the retainer 11 while eliminating the left side support member 45 and reducing the number of necessary members.

According to the above-described second embodiment, the following effects are obtained.
(1) The central horizontal fin 15A (an example of one fin) of the plurality of horizontal fins 15 is the first of the two end faces (right end face 33, left end face 34) formed on both sides in the axial direction. The second rotation shaft 32 is provided on the left end surface 34 opposite to the right end surface 33 on which the one rotation shaft 31 is formed. The second rotating shaft 32 is inserted into a bearing hole 11E formed in the retainer 11, and is rotatably held by the retainer 11. The operation knob 17 is attached to the central horizontal fin 15A. The operation knob 17 has a fin insertion hole 17C into which the central horizontal fin 15A is inserted, and is formed of one member.

According to this, the operation knob 17 formed of one member can be inserted from one side (left side) of the central horizontal fin 15A and attached to the central horizontal fin 15A. Then, by inserting the second rotary shafts 32 of the plurality of horizontal fins 15 including the central horizontal fins 15A to which the operation knob 17 is attached into the bearing holes 11E of the retainer 11, the plurality of horizontal fins 15 are attached to the retainer 11. You can As a result, the assemblability of the operation knob 17 and the horizontal fin 15 to the retainer 11 can be improved. Further, since the retainer 11 directly holds the second rotary shaft 32, it is not necessary to provide the left side support member 45 or the like for holding the second rotary shaft 32, and the number of members required for the register 10 is reduced, thereby reducing the manufacturing cost. Can be planned.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various improvements and modifications can be made without departing from the spirit of the present invention.

That is, the first rotary shaft 31 and the rod shaft 41 may be projected in the direction toward the right end surface 33 of the horizontal fin 15. In this case, the right side support member 37 can be arranged inside (left side) of the position of the connecting portion 39.
Further, the recess 55A of the accommodating portion 51 may be in contact with the first rotating shaft 31. For example, the recess 55A may have a structure in which the recess 55A comes into contact with the first rotating shaft 31 in accordance with the displacement of the first rotating shaft 31 and suppresses the displacement of the first rotating shaft 31.

Further, the register 10 may not include the vertical fin 19.
Further, the fin in the present application is not limited to the horizontal fin 15, and may be the vertical fin 19.
