Jikkenhei 1-140447

However, in the above configuration, air leaks to the vehicle interior side from the gap between each of the two surfaces provided with the rotating shaft of the barrel and the retainer. This is because the barrel needs to be rotatably supported by the retainer, and a gap is inevitably formed between the two. In particular, when the adjacent fins are rotated so as to partially overlap each other to substantially close the opening in the barrel, air leakage from the gap becomes remarkable.

The present invention has been made in view of the above circumstances, and one of the objects thereof is to provide a vehicle register capable of reducing air leaking to the vehicle interior side from a gap between a barrel and a retainer with a simple configuration. It is in.

The vehicle register according to the first aspect of the present invention is
A retainer that forms an air outlet toward the passenger compartment,
A vehicle register including a barrel that changes the air blowing direction by rotating inside the retainer.
The target to which the barrel or the vehicle register is attached is
The barrel is provided with a shielding portion that covers the gap formed between the two constituent surfaces facing each other and the retainer from the vehicle interior side.

According to the vehicle register, it is possible to prevent air from leaking from the gap formed between the barrel and the retainer. This is because the shielding portion covers the gap from the vehicle interior side. It is also possible to reduce the ventilation noise of the air passing through the gap. The air passing through the gap hits the shielding portion on the outlet side of the retainer. Therefore, the wind speed of the air passing through the gap is reduced.

[Embodiment 1]
Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 5. Here, the first embodiment will be described by taking the vehicle register 1 provided on the instrument panel 30 as an example. In the following description, the vehicle interior side of the vehicle register 1 is the front side, the opposite side is the back side, and the top, bottom, left, and right of the vehicle register 1 correspond to the top, bottom, left, and right of the vehicle. Further, the vehicle register 1 may be simply referred to as a register 1. In each figure, some of the constituent members of the barrel 20 are omitted. For example, in FIGS. 1 and 6, the fixed fins described later are omitted, and in FIGS. 2 to 5, the movable fins 23 and the fixed fins described later are omitted.

[Overview]
As shown in FIG. 1, the register 1 according to the first embodiment has a retainer 10 that forms an air outlet toward the vehicle interior and a barrel that changes the air blowing direction by rotating inside the retainer 10. 20 and. In FIG. 1, the lower part of the paper surface is the vehicle interior side. One of the features of the register 1 of this example is that the barrel 20 includes a shielding portion 20c that covers a specific gap G formed between the barrel 20 and the retainer 10. Hereinafter, each member will be described in detail.

[Retainer]
The retainer 10 is a member fixed to a component member of the vehicle facing the passenger compartment, and forms an air outlet on the passenger compartment side (FIGS. 2 to 4). In this example, the component member of the vehicle facing the passenger compartment is the instrument panel 30. The retainer 10 is a tubular member that opens to the front side (vehicle interior side) and the back side. An HVAC (Heating, Ventilation, and Air Conditioning) unit (not shown) is connected to the opening on the back side of the retainer 10 via a duct 40 shown by a chain double-dashed line in FIG. The HVAC unit is an air conditioning unit that supplies air to a predetermined air outlet as air conditioning air having an appropriate temperature and air volume by dehumidifying, cooling, and heating the inside air or the outside air with a heat exchanger. The cross-sectional shape of the retainer 10 is a shape corresponding to the shape of the duct 40 and the air outlet. Specific examples of the cross-sectional shape of the retainer 10 include a rectangle and a circle.

In this example, a retainer 10 having a rectangular cross-sectional shape consisting of upper and lower surfaces 10 _U and 10 _D and left and right side surfaces 10 _L and 10 _R is used. The upper and lower surfaces 10 _U and 10 _D of the retainer 10 of this example are rectangular surfaces (FIGS. 3 and 4). On the other hand, the side surface ₁₀ L, 10 _R of the right and left retainer 10 includes a barrel supporting portion ₁₁ L, 11 _R of the front side, and an extension portion ₁₂ L, 12 _R connected to the rear side of the barrel supporting portion ₁₁ L, 11 _R Have.

The barrel support portions 11 _L and 11 _R may have a shape corresponding to the end face shape of the barrel 20, which will be described later. The barrel support portions 11 _L and 11 _R of this example are substantially disk-shaped members. A support hole 10h into which the rotation shaft 20a of the barrel 20 is fitted is formed in the central portion of the barrel support portions 11 _L and 11 _R. Notches 10c are formed above and below the barrel support portions 11 _L and 11 _R. The shape of the notch 10c is a bow shape surrounded by an arc and a string that form a part of the peripheral edge of the disk. The bow-shaped notch 10c prevents the shielding portion 20c of the barrel 20 from interfering with the barrel support portions 11 _L and 11 _R when the barrel 20 described later is fitted into the retainer 10. Although omitted in FIGS. 3 and 4, it is preferable to provide a guide groove for the rotation shaft 20a of the barrel 20 on the inner surfaces of both barrel support portions 11 _L and 11 _R. This guide groove is, for example, a groove along the radial direction from the peripheral edge of the barrel support portions 11 _L and 11 _{R on} the vehicle interior side to the support hole 10h. When fitting the barrel 20 into the retainer 10 from the vehicle interior side, the barrel 20 can be easily assembled to the retainer 10 by fitting the rotating shaft 20a of the barrel 20 into the guide groove and sliding it to the support hole 10h.

The extension portions 12 _L and 12 _R are plate-shaped members having a semicircular notch on the front side of the rectangular surface. The extension portions 12 _L and 12 _R form an opening on the back surface side with the upper and lower surfaces 10 _U and 10 _D of the retainer 10. A duct 40 (FIG. 1) connected to the HVAC unit is connected to the opening on the back side. The barrel support portions 11 _L and 11 _R and the extension portions 12 _L and 12 _R are connected only at the intermediate portion in the vertical direction of the two. Of the side surfaces 10 _{L and} 10 _R of the retainer 10, slits 10s are formed above and below the connecting portion. The slit 10s is formed in an arc shape concentric with the rotation shaft 20a of the barrel 20 and the support holes 10h of the barrel support portions 11 _L and 11 _R. In other words, the slit 10s is provided corresponding to the locus of the flange surface 21c of the shielding portion 20c when the barrel 20 is rotated. The slit 10s prevents the shielding portion 20c of the barrel 20 from interfering with the extension portions 12 _L and 12 _R when the barrel 20 is rotated in the retainer 10.

Plastic is suitable as the constituent material of such a retainer 10. For example, if plastic is injection molded, a retainer having a complicated shape can be easily molded.

[barrel]
The barrel 20 is a member that is rotatably provided inside the retainer 10 via a rotation shaft 20a and has openings on the front side and the back side. The conditioned air supplied from the HVAC unit to the retainer 10 via the duct 40 is blown into the passenger compartment through the inside of the barrel 20. By rotating the barrel 20 in the retainer 10, the air blowing direction is controlled. In the barrel 20 of this example, the opening on the passenger compartment side is rotated up and down by the rotation shaft 20a substantially along the vehicle width direction, and the air blowing direction is changed up and down. The shape of the barrel 20 may be any shape having openings on the front side and the back side. Specific examples of the shape of the barrel 20 include a square cylinder, a cylinder, a sphere, and the like.

The barrel 20 of this example has a cylindrical, disc-shaped end surface 20 _L, 20 _R and a pair of connecting surfaces 20 _U , 20 _D connecting both end surfaces 20 _L, 20 _R (FIGS. 3, FIG. 4). The disc-shaped both end faces 20 _{L and} 20 _R correspond to two constituent faces facing each other in the barrel 20. The two constituent surfaces facing each other in this example are two surfaces facing each other in the rotation axis direction of the barrel 20. The peripheral edge of these two constituent surfaces including the edge on the vehicle interior side is an arc shape centered on the rotation shaft 20a of the barrel 20. At the center of both end surfaces 20 _{L and} 20 _R , a shaft portion projecting outward of the barrel 20 is provided. This shaft portion serves as the rotation shaft 20a of the barrel 20. Instead of forming the rotating shaft 20a integrally with the barrel 20, a rotating shaft may be used in which a shaft hole is formed at the center of both end faces 20 _{L and} 20 _R and is separately inserted into the shaft hole. The extension direction of the rotation shaft 20a of the barrel 20 may be appropriately set according to the installation target and the installation direction of the register 1. In this example, the extension direction of the rotation shaft 20a of the barrel 20 is generally along the vehicle width direction, but the extension direction is not limited to this.

The pair of connecting surfaces 20 _U and 20 _D of this example are composed of arcuate curved surfaces. The arcuate curved surface is composed of a region left as a result of partially cutting out the substantially opposite positions of the outer peripheral surface of the cylinder. The formation range of these curved surfaces in the circumferential direction is such that there is no gap between the upper and lower surfaces 10 _U and 10 _D of the retainer 10 at any rotation end in the rotation direction of the barrel 20. It may be set appropriately according to the moving angle. The rotation angle of the barrel 20 of this example is ± 30 ° with respect to the horizontal direction as the reference position. Therefore, the formation range of the pair of arcuate curved surfaces is also set to about 30 ° at the central angle. At the reference position of the barrel 20, the passenger compartment side edge of the upper and lower surfaces 10 _U and 10 _D of the retainer 10 and the passenger compartment side edge of the pair of arcuate curved surfaces are substantially on the vertical plane. Become one. An opening surrounded by a pair of arcuate curved surfaces and both end faces 20 _{L and} 20 _R constitutes an opening on the front side and the back side of the barrel 20.

Shielding portions 20c are provided on both end faces 20 _{L and} 20 _R of the barrel 20. The shielding portion 20c has two surfaces facing each other in the rotation axis direction of the barrel 20, that is, a gap G formed between both end surfaces 20 _{L and} 20 _{R of the} barrel 20 and both side surfaces 10 _{L and} 10 _R of the retainer 10. Cover from the passenger compartment side. When the register 1 is viewed from the vehicle interior side, the shielding portion 20c is provided so as to overlap the gap G between both end surfaces 20 _{L and} 20 _R of the barrel 20 and both side surfaces 10 _{L and} 10 _R of the retainer 10. .. The forming range of the shielding portion 20c on the peripheral edges of both end faces 20 _{L and} 20 _R of the barrel 20 may be appropriately set according to the rotation angle of the barrel 20. The forming range of the shielding portion 20c in this example is a range of about 240 ° at the central angle centered on the rotation shaft 20a of the barrel 20. About 240 ° of this central angle is a value obtained by adding ± 30 °, that is, 60 °, which is the rotation range of the barrel, to 180 °. By providing the shielding portion 20c in a predetermined range in the circumferential direction on both end surfaces of the barrel 20, the gap G can be covered from the vehicle interior side regardless of the rotation angle of the barrel 20.

As shown in FIGS. 3 and 4, the shielding portion 20c of this example is an arc-shaped member protruding outward from the outer peripheral edge of both end faces 20 _{L and} 20 _R. The shielding portion 20c has a flange surface 21c and a folded surface 22c. The flange surface 21c is a surface connected to the peripheral edges of both end surfaces 20 _{L and} 20 _R of the barrel 20 mainly on the passenger compartment side. The folded surface 22c is a surface extending from the flange surface 21c in the rotation axis direction of the barrel 20 and parallel to both end surfaces 20 _{L and} 20 _{R of} the barrel 20 at intervals. When the barrel 20 is viewed in a horizontal cross section, the shielding portion 20c is provided so as to be folded back from the peripheral edge on the front side to the back side on both end faces 20 _{L and} 20 _R of the barrel 20 (FIG. 5). The width of the flange surface 21c of the shielding portion 20c (dimension in the rotation axis direction of the barrel 20) is formed between both end faces 20 _{L and} 20 _R of the barrel 20 and both side surfaces 10 _{L and} 10 _R of the retainer 10. It may be wider than the gap G. Both ends of the flange surface 21c of the shielding portion 20c in the circumferential direction are located on the back surface side of the barrel 20. The distance Hb between both ends of the flange surface 21c is wider than the vertical dimension Hr of the barrel support portions 11 _L and 11 _R of the retainer 10 (FIG. 3). This is because the flange surface 21c of the shielding portion 20c does not interfere with the barrel supporting portions 11 _L and 11 _R when the barrel 20 is assembled to the retainer 10. The width of the folded surface 22c of the shielding portion 20c (diametrical dimensions of the end faces 20 _{L and} 20 _R of the barrel 20) may be about 30% or less of the radius of both end faces 20 _{L and} 20 _R of the barrel 20. Each folded surface 22c of the shielding portion 20c is fitted into the groove portion 30g of the instrument panel 30 described later. As a result, the air passing through the gap G formed between both end faces 20 _{L and} 20 _R and both side faces 10 _{L and} 10 _R of the retainer 10 is composed of the shielding portion 20c and the groove portion 30g of the instrument panel 30. It will take a substantially S-shaped bent path (Fig. 5). The shielding portion 20c of this example is a member having an L-shaped cross section having a flange surface 21c and a folded surface 22c, but the folded surface 22c may be omitted and only the flange surface 21c may be used.

Further, as shown in FIG. 1, it is preferable to provide a rotatable movable fin 23 in the barrel 20 (omitted in FIGS. 2 to 5). The movable fin 23 is a plurality of plate-shaped members arranged in parallel in the direction of the rotation axis of the barrel 20 with an axis orthogonal to the rotation axis 20a of the barrel 20 as the rotation axis 23a. In FIG. 1, the rotation shaft 23a of each movable fin 23 extends in the vertical direction of the paper surface. That is, the rotation shaft 23a of the movable fin 23 is bridged between the pair of connecting surfaces 20 _U and 20 _D constituting the barrel 20. The movable fin 23 of this example is rotated between a fully open state along the axis from the back side to the front side in the barrel 20 and a closed state along the rotation shaft 20a of the barrel 20. In FIG. 1, the movable fin 23 in the fully open state is shown by a solid line, and the movable fin 23 in the closed state is shown by a chain double-dashed line. In the fully open state, air circulates between the movable fins 23 in the barrel. In the closed state, the adjacent movable fins 23 partially overlap each other, thereby substantially blocking the space through which the air flows in the barrel 20. Air is blown out in a direction corresponding to the angle of the movable fin 23 between the fully open state and the closed state. Therefore, in the movable fin 23 of this example, the air blowing direction can be changed in the left-right direction (vehicle width direction) of the register 1 by its rotation. The rotation shaft 23a of the movable fin 23 is preferably provided in a direction orthogonal to the rotation shaft 20a of the barrel 20. However, the rotation shaft 23a of the movable fin 23 may be provided in parallel with the rotation shaft 20a of the barrel 20.

In addition, although not shown, it is also preferable to provide fixed fins to be bridged between both end faces in the opening on the front side of the barrel 20. The fixed fins are composed of, for example, a plurality of strip-shaped plate members, and are arranged in parallel at intervals in a direction orthogonal to the parallel direction of the movable fins 23 (in this example, the vertical direction). By rotating the barrel 20 in the retainer 10 in the vertical direction, air can be guided in the direction along the fixed fins. The fixed fins may be configured by providing a grid-like plate material in the opening on the front side of the barrel 20. Movable fins may be provided in the opening on the front side of the barrel 20 instead of the fixed fins. In that case, it is preferable that the rotation shaft 23a of the movable fin 23 provided inside the barrel 20 and the rotation shaft of the movable fin provided in the opening on the front side of the barrel 20 are orthogonal to each other.

Plastic is suitable as the constituent material of such a barrel 20. For example, by injection molding plastic, a barrel 20 having a complicated shape can be easily molded.

[Register installation target]
The register 1 is attached to a component of the vehicle facing the passenger compartment. Specific examples of the components of this vehicle include the instrument panel 30, the center console (particularly the surface facing the rear seats), the inner panel of each pillar and the garnish covering it, and the ceiling (for example, an overhead console or a roofside inner panel). And at least one of the garnishes that cover it). The mounting target of this example is the instrument panel 30 as described above. The schematic configuration around the register of the instrument panel 30 will be described mainly with reference to FIGS. 3 and 4. In each figure, the instrument panel 30 is shown by cutting out only a part around the register. The instrument panel 30 is formed with an opening through which the barrel 20 of the register 1 is exposed. The opening is configured by being surrounded by the upper piece 30 _U and the lower piece 30 _D, and the upper piece 30 _U connecting piece ₃₀ of the pair of connecting the lower piece 30 _D and L, 30 _R. The upper piece 30 _U and the lower piece 30 _D are flat plate members facing the passenger compartment. The connecting pieces 30 _{L and} 30 _R are a semicircular plate along the direction orthogonal to the upper piece 30 _U and the lower piece 30 _D , and a circle extending from the peripheral edge of the semicircular plate in the rotation axis direction of the barrel 20. It has an arc-shaped curved plate. That is, the connecting pieces 30 _{L and} 30 _R are provided so as to project toward the vehicle interior side from the upper piece 30 _U and the lower piece 30 _D of the instrument panel 30.

The semicircular plate constituting the connecting pieces 30 _{L and} 30 _R has an arcuate outer peripheral end face. A groove portion 30 g is provided on the outer peripheral end surface. The groove portion 30 g is provided over the entire length of the outer peripheral end surface of the semicircular plate. The flange surface 21c of the shielding portion 20c described above is fitted into the groove portion 30g. Both side walls of the groove 30g are formed between the inner side wall 31i interposed between the end faces 20 _{L and} 20 _R of the barrel 20 and the folded surface 22c of the shielding portion 20c and the folded surface of the shielding portion 20c between the inner side wall 31i. It is composed of an outer wall 31o with 22c interposed therebetween. The inner wall 31i is smaller than the outer wall 31o. The outer peripheral end surface of the inner side wall 31i and the outer peripheral end surface of the outer wall 31o are concentric semicircular arcuate surfaces. Half-bow-shaped notches are provided at the vertical positions of the inner side wall 31i. Due to this notch, the dimension Hi (FIG. 4) between the upper and lower edges of the inner side wall 31i is smaller than the distance Hb (FIG. 3) between both ends in the circumferential direction of the flange surface 21c of the shielding portion 20c. Therefore, when the barrel 20 is fitted into the opening of the instrument panel 30 from the vehicle interior side, it is possible to prevent the flange surface 21c of the shielding portion 20c from interfering with the inner side wall 31i.

When the register 1 attached to the instrument panel 30 is viewed from the vehicle interior side, the flange surface 21c of the shielding portion 20c in the barrel 20 and the curved plate constituting the connecting pieces 30 _{L and} 30 _R of the instrument panel 30 are substantially present. It is preferable that they are flush with each other. This is because it is possible to eliminate a step at the boundary between the register 1 and the instrument panel 30.

[Assembly procedure]
The above register 1 is assembled as follows.
(1) The retainer 10 is fixed to the back side of the instrument panel 30. By this fixing, the barrel support portions 11 _L and 11 _R of the retainer 10 are arranged inside the connecting pieces 30 _{L and} 30 _R (semi-circular plate) of the instrument panel.

(2) The barrel 20 is fitted into the opening of the instrument panel 30 from the front side (vehicle interior side). Both end faces 20 _{L and} 20 _R of the barrel 20 are arranged between both side faces 10 _{L and} 10 _R of the retainer 10 fixed to the instrument panel 30.

(3) Further push the barrel 20 toward the back side, and fit the barrel 20 into the retainer 10. At that time, the folded surface 22c of the shielding portion 20c is fitted into the groove portion 30g of the semicircular plate of the instrument panel 30. That is, as shown in FIG. 5, between the end faces 20 _{L and} 20 _R of the barrel 20 and the folded surface 22c of the shielding portion 20c, the barrel support portions 11 _L and 11 _R of the retainer 10 and the connecting pieces 30 _{L and} 30 _R The inner side wall 31i is interposed. At the same time, the rotating shaft 20a of the barrel 20 is fitted into the support holes 10h formed in the barrel support portions 11 _L and 11 _R of the retainer 10.

[Action effect]
The above register 1 has the following effects.
(1) It is possible to suppress air leakage from the gap G formed between both end faces 20 _{L and} 20 _{R of the} barrel 20 and both side surfaces 10 _{L and} 10 _R of the retainer 10. This is because the shielding portion 20c covers the gap G from the vehicle interior side.

(2) It is also possible to reduce the ventilation noise of the air passing through the gap G described above. The air passing through the gap G abuts on the shielding portion 20c on the outlet side of the retainer 10. At that time, the wind speed of the air passing through the gap G is reduced.

(3) A shielding portion 20c is provided on the front side of the barrel 20, and the shielding portion 20c has a flange surface 21c that overlaps the gap G so that the rotation shaft 20a of the barrel 20 cannot be seen from the front side of the register 1. Can be. When the side surfaces 10L and 10R of the retainer 10 have guide grooves for guiding the rotation shaft 20a of the barrel 20, the end of the guide groove that opens to the front side of the register 1 can also be hidden by the flange surface 21c of the shielding portion 20c. .. Therefore, the appearance of the register 1 from the front side can be improved.

(4) Additional components other than the barrel 20 in order to shield the gap G formed between both end faces of the barrel 20 and both side surfaces of the retainer 10 by integrating the shielding portion 20c with the barrel 20. There is no need to use. For example, when a filler such as felt is attached to both end faces of the barrel 20 in order to fill the gap G, the filler is required and the work of attaching the filler to both end surfaces 20 _{L and} 20 _R of the barrel 20 is also performed. You will need it. The register 1 of this example does not require an additional component such as a filler, and the assembly work is easy.

(5) By providing the shielding portion 20c on the front side of the barrel 20, it is sufficient to change the size of the register 1 or the size of the duct 40 connected to the retainer 10 by adding the shielding portion 20c to the existing barrel 20. There is no need to change. When a shielding portion is provided on the back side of the register 1, for example, the back side on the side surfaces 10 _{L and} 10 _R of the retainer 10 is bypassed by the rear end edge on each end face 20 _{L and} 20 _R of the barrel 20 and the front side. It is conceivable that the configuration will be folded back to. In that case, a part of the side surfaces 10 _{L and} 10 _R of the retainer 10 wraps around inside the barrel 20. Therefore, it is allowed that the cross section of the air flow path becomes smaller and the pressure loss increases, or the size of the register 1 itself, particularly the distance between the side surfaces 10 _{L and} 10 _{R of the} retainer 10 and the end faces 20 _{L and} 20 of the barrel 20. _It is necessary to widen the distance between _Rs . On the other hand, in the register 1 of this example, it is not necessary to narrow the cross section of the flow path or change the size of the register 1 and the duct 40.

(6) Since the shielding portion 20c includes not only the flange surface 21c but also the folded surface 22c, it is possible to guide the air passing through the gap G so as to be folded back to the back side. Therefore, it is possible to more effectively reduce the air leaking to the front side through the gap G as compared with the case where there is only the shielding portion 20c having only the flange surface 21c.

(7) By providing slits 10s corresponding to the rotation locus of the barrel 20 on the side surfaces 10 _{L and} 10 _R of the retainer 10, when the barrel 20 is rotated, the flange surface 21c of the shielding portion 20c becomes the side surface 10 of the retainer 10. It is possible to prevent interference with the extension portions 12 _L and 12 _R constituting _{L and} 10 _R.

(8) If the flange surface 21c of the shielding portion 20c in the barrel 20 and the curved plate constituting the connecting pieces 30 _{L and} 30 _R of the instrument panel 30 are substantially flush with each other, the appearance of the register 1 is improved. Can be done.

[Embodiment 2]
The second embodiment, which has a different configuration from the first embodiment, will be described with reference to FIG. In the first embodiment, the folded surface 22c of the shielding portion 20c is fitted into the groove 30g provided in the connecting pieces 30 _{L and} 30 _R of the instrument panel 30, but the folded surface 22c of the shielding portion 20c is fitted to the retainer 10. It may be configured to be fitted between the side surfaces 10 _{L and} 10 _R and the connecting pieces 30 _{L and} 30 _R of the instrument panel 30. The following description will be given mainly on the differences from the first embodiment, and the description of the common configuration will be omitted.

In the instrument panel 30 of this example, the connecting pieces 30 _{L and} 30 _R along the axis extending from the front side to the back side do not have the groove portion 30 g, but are substantially composed of a flat plate member. However, a step is provided in the vicinity of the opening of the instrument panel 30 of the connecting pieces 30 _{L and} 30 _R. On the other hand, the side surfaces 10 _{L and} 10 _R of the retainer 10 are extended to the front side of the first embodiment. Therefore, a gap G is formed between the stepped portion of the connecting pieces 30 _{L and} 30 _R and the side surfaces 10 _{L and} 10 _R of the retainer 10. The folded surface 22c of the shielding portion 20c is fitted into this gap G.

Even with the configuration of this example, the same effect as that of the first embodiment can be obtained.

It should be noted that the present invention is not limited to these examples, and is indicated by the scope of claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims. For example, at least one of the following modifications can be applied to each of the above embodiments.

(1) In both the first and second embodiments described above, the rotation shaft 20a of the barrel 20 extends in the vehicle width direction, but the rotation shaft 20a of the barrel 20 extends in the vertical direction of the vehicle. May be good. In that case, the barrel 20 is rotated in the retainer 10 in the left-right direction of the vehicle.

(2) The above-described first and second embodiments both include a shielding portion 20c having a flange surface 21c formed of a straight piece and having an L-shaped cross section and a folded surface 22c, but have different shapes. The shielding portion 20c may be used. For example, the folded surface 22c of the shielding portion 20c may have a curved surface instead of a straight piece, or the folded surface 22c of the shielding portion 20c may extend in a direction inclined with respect to both end surfaces 20 _{L and} 20 _R of the barrel 20. It can be shaped. Of course, the width of the folded surface 22c of the shielding portion 20c may be made longer.

(3) A frame-shaped bezel may be provided in the opening of the retainer 10 on the passenger compartment side.

(4) Each of the above-described first and second embodiments has a configuration in which the barrel 20 is provided with the shielding portion 20c. On the other hand, the shielding portion 20c may be provided on the vehicle mounting target (not shown). For example, when the vehicle is mounted on the instrument panel 30, the instrument panel 30 is formed with an opening in which the barrel 20 of the register 1 is exposed. The opening is configured by being surrounded by the upper piece 30 _U and the lower piece 30 _D, and the upper piece 30 _U connecting piece ₃₀ of the pair of connecting the lower piece 30 _D and L, 30 _R. In the instrument panel 30, the shielding portion 20c may be formed by folding back the portions facing both ends of the rotating shaft 20a of the barrel 20, that is _, the opening edges of the pair of connecting pieces 30 _{L and} 30 _R. For example, the folded shielding portion 20c is configured to cross the peripheral edge on the opening side of both end faces 20 _{L and} 20 _R of the barrel 20 from the outside to the inside of the barrel 20 and further bend to the back side. Even with this configuration, the gap G formed between both end faces 20 _{L and} 20 _{R of} the barrel 20 and the retainer 10 is covered by the shielding portion 20c from the vehicle interior side. Therefore, it is possible to prevent air from leaking from the gap G. Even in this case, the shielding portion 20c is not a folded structure, and may simply cross the peripheral edge on the opening side of both end faces 20 _{L and} 20 _R of the barrel 20 from the outside to the inside of the barrel 20.
