Description

  The present invention relates to a display device provided with wrinkles and a method for manufacturing the display device.

  Conventionally, a display device mounted on a vehicle or the like is known. For example, the display device described in Patent Document 1 includes a dial plate provided with respect to a pointer and a ring-shaped member provided so as to surround the outer periphery of the dial plate. The ring-shaped member has an inclined wall that curves and extends forward from the back side of the dial. In this case, a step is formed between the inclined wall and the dial, and the three-dimensional effect is emphasized by this step to enhance the appearance of the display device.

JP 2005-134303 A

  However, merely forming a step between the ring-shaped member and the dial plate has a limit in improving the appearance of the display device.

  In view of this, a configuration is conceivable in which the appearance of the display device is enhanced by providing a textured surface with a large number of textures on the ring-shaped member. Here, chemical processing such as etching can be given as a method for imparting the textured surface to the ring-shaped member, but due to the use of the chemical corrosive action in chemical processing, the textured surface is not intended. There is concern about becoming. In this case, the appearance of the display device is impaired by giving the texture.

  The present invention has been made in view of the above problems, and an object of the present invention is to enhance the appearance of a display device with a texture.

  The technical means of the invention for achieving the object will be described below. The reference numerals in parentheses described in the scope of claims and this column disclosing technical means of the invention indicate the correspondence with the specific means described in the embodiment described in detail later. It is not intended to limit the technical scope of the invention.

The side surface of the embossing faces forward or extends along the display direction of the display unit.

  According to the present invention, since the texture is arranged on each of the plurality of plate surfaces, the appearance of the display device can be enhanced by a combination of the plurality of plate surfaces and the installation manner of the texture. Moreover, since the shape of each embossment has regularity, these embossments can be formed by die processing. In the die processing, the embossing mode can be set finely by properly arranging the depressions such as dimples at the desired positions with respect to the die. For this reason, it can avoid that the appearance of a display apparatus is impaired by the state which the installation aspect of a wrinkle becomes in an unintended state.

  Moreover, since each texture has a shape that does not hinder the removal of the mold from the partition member, there is no need to perform so-called forced removal. For this reason, it is possible to suppress that the texture is deformed or a part of the texture is shaved when the mold is removed and the texture of the partition member due to the texture is not intended.

The color filter substrate has a red filter, a green filter, and a blue filter, and each filter is arranged for each pixel (each electrode). In addition, a thin film transistor (TFT) (not shown) that turns on and off each pixel is provided. The polarizing film is a filter that transmits light that vibrates in a predetermined direction and restricts the vibration direction of the light to a predetermined direction. The pair of polarizing films are arranged so that the vibration direction is shifted by 90 degrees. This TFT liquid crystal panel has a known structure.

  The protection plate 16 has translucency and is overlaid on the display surface of the liquid crystal panel 15. In this case, a user such as a driver can visually recognize the image on the liquid crystal panel 15 via the protective plate 16. The light shielding plate 17 has a light shielding property and restricts light from leaking rearward or sideward from the liquid crystal panel 15.

  The vehicle display device 10 includes a case 21 that covers the meters 11 and 12 and the intermediate display unit 13 from the rear, a turning member 22 provided on the front side of the case 21, a cover 23 that covers the turning member 22 from the front, And a circuit board 24 accommodated in the case 21. The facing member 22 surrounds the front space of the meters 11 and 12 and the intermediate display unit 13, and corresponds to a partition member that partitions the front space. Both the case 21 and the facing member 22 are made of a synthetic resin material and have a light-impermeable property. The cover 23 is made of a synthetic resin material, has transparency, and is attached to the front end portion of the turning member 22. The circuit board 24 is disposed behind the meters 11 and 12 and the intermediate display unit 13.

  The meters 11 and 12 include a display board 31 provided with a display surface facing the seat side, an index 32 such as a scale or letters, and a pointer 33 indicating the index 32. The display board 31 has a circular shape, and a plurality of indicators 32 are arranged at predetermined intervals along the peripheral edge of the display board 31. Here, the display board 31 has the display base material which formed the front surface, and the printing layer superimposed on the rear surface of the display base material, and the parameter | index 32 is the non-installation part of the printing layer in the display board 31. It is formed by. The display substrate is formed in a plate shape from polycarbonate resin or the like, and the printing layer is formed from a colorant, a vehicle, and an additive. While the display substrate has translucency, the printed layer has light shielding properties, and in the display panel 31, the transmissivity of the indicator 32 is larger than the transmissivity of other portions. It has become.

  The vehicle display device 10 includes a light emitting unit 41 as a light source provided behind the display plate 31 and a light guide plate 42 that emits light of the light emitting unit 41 toward the display plate 31. The light emitting unit 41 includes a plurality of LEDs having different emission colors as a light emitter, and is mounted on the front surface of the circuit board 24. The circuit board 24 has a light emitting circuit capable of causing the light emitting unit 41 to emit light, and the light emitting unit 41 emits light in a predetermined color according to a command signal for the light emitting circuit.

  The light guide plate 42 is overlaid on almost the entire display plate 31 from the rear, and the light emitting unit 41 is disposed at a position spaced rearward from the light guide plate 42. Here, when the light of the light emitting unit 41 is incident from the rear surface of the light guide plate 42, the light travels through the light guide plate 42, so that the entire front surface of the light guide plate 42 emits light with substantially the same brightness. In this case, almost the entire display panel 31 is uniformly illuminated from behind by the light of the light emitting unit 41.

  The display plate 31 and the light guide plate 42 are both formed in a flat plate shape. A part of the display plate 31 is disposed in front of the liquid crystal panel 15 and the protection plate 16, and in this portion, the light guide plate 42 enters between the display plate 31 and the protection plate 16. Yes. For this reason, in the liquid crystal panel 15 and the protection plate 16, a part of each is hidden behind the display plate 31 and is disposed at an intermediate position between the first meter 11 and the second meter 12. The portion forms the intermediate display portion 13.

  The pointer 33 is disposed on the front side of the display plate 31, and the rotation axis of the pointer 33 overlaps a center line O passing through the center of the display plate 31. Here, the vehicle display device 10 includes a drive unit 43 for rotating the pointer 33 and a pointer shaft unit 44 that connects the drive unit 43 to the pointer 33. The drive unit 43 is attached to the circuit board 24 and penetrates both the display plate 31 and the light guide plate 42.

  The facing member 22 includes a facing outer peripheral portion 51 that extends along the peripheral portion of the cover 23 and a facing ring portion 52 that extends along the peripheral portions of the meters 11 and 12. The facing outer peripheral part 51 is an elliptical cylindrical part opened front and rear, and the opened part is closed from the front and rear by the cover 23 and the case 21. The facing ring part 52 is a perfect circular cylindrical part opened forward and backward, and extends along the peripheral edge of the display plate 31 in each of the meters 11 and 12. The facing ring portions 52 are arranged so as to be spaced apart from each other, and are in a state of straddling the peripheral edge portion of the display plate 31 inward and outward in the respective radial directions.

  Further, the facing member 22 includes facing connection portions 53 and 54 in which two facing ring portions 52 are connected. The upper facing connection portion 53 and the lower facing connection portion 54 are arranged vertically with the intermediate display portion 13 in between.

  The facing ring portion 52 and the facing connection portions 53 and 54 are all disposed on the inner peripheral side of the facing outer peripheral portion 51, and a part of each is connected to the facing outer peripheral portion 51.

  The counter ring part 52 has a shape in which the intermediate part is bent at an acute angle toward the front in the radial direction. Specifically, the facing ring portion 52 includes an inner peripheral ring 56 that forms an inner peripheral end thereof and an outer peripheral ring 57 that forms an outer peripheral end thereof. 57 is connected to the inner peripheral end. The inner peripheral ring 56 is a plate portion linearly extending obliquely forward from the front position of the display plate 31 toward the outer peripheral side, and the outer peripheral ring 57 is directed from the front end portion of the inner peripheral ring 56 toward the outer peripheral side. It is a plate part that extends obliquely rearward in a straight line. In this case, at the front position of the liquid crystal panel 15, the rear end face of the outer peripheral ring 57 is superimposed on the front surface of the protection plate 16, and at the side position of the liquid crystal panel 15, the rear end face of the outer peripheral ring 57 is turned back. It is connected to the outer peripheral part 51 and the look-back connection parts 53 and 54.

  The facing member 22 is provided with a printing layer by applying silver printing on the front surface, and the entire printed color in each of the facing outer peripheral portion 51, the facing ring portion 52 and the facing connection portions 53 and 54. The density of the is uniform. In particular, the front surfaces 53a and 54a of the facing connection portions 53 and 54, the front surface 56a of the inner peripheral ring 56, and the front surface 57a of the outer peripheral ring 57 are embossed surfaces having a number of embossments 61 (see FIG. 4). The surface is printed.

  In the turning outer peripheral portion 51, the inner peripheral surface is a front surface 51a, and the front surface 51a is not provided with a texture. On the front surface 51a, black printing for suppressing light reflection is performed, and then silver printing is performed on the printed layer. On the other hand, in the textured surfaces such as the front surfaces 53a, 54a, 56a, and 57a, the effect of suppressing the reflection of light without performing black printing due to the fact that the light is difficult to reflect in one direction. Can get to.

  The facing connection portions 53 and 54, the inner peripheral ring 56 and the outer peripheral ring 57 are plate portions. The front surfaces 53a and 54a of the facing connection portions 53 and 54, the front surface 56a of the inner peripheral ring 56 and the front surface 57a of the outer peripheral ring 57. Corresponds to a plurality of section screens extending in directions crossing each other. In particular, the front surface 57a of the outer ring 57 corresponds to a specific section screen.

  As shown in FIG. 3, on the front surface 53 a of the upper facing connection portion 53 and the front surface 56 a of the inner peripheral ring 56, the wrinkle density, which is the number of the wrinkles 61 per unit area, is made uniform. Is not granted. However, the wrinkle density N1 of the upper facing connection portion 53 is larger than the wrinkle density N2 of the inner ring 56.

  On the other hand, the wrinkle density is not made uniform on the front surface 54a of the lower facing connection portion 54 and the front surface 57a of the outer peripheral ring 57. The wrinkle density of the lower side connection portion 54 is highest at the end portion on the intermediate display portion 13 side, and gradually decreases as the distance from the intermediate display portion 13 increases. The largest texture density N3 in the lower facing connection portion 54 is smaller than the texture density N1 of the upper facing connection portion 53, and the smallest texture density N4 is larger than the texture density N2 of the inner peripheral ring 56. .

  The wrinkle density of the outer peripheral ring 57 is the largest at the rear end, and gradually decreases as it approaches the front end. The largest wrinkle density in the outer peripheral ring 57 is set to be the same as the wrinkle density N1 of the upper facing connection portion 53, and the smallest wrinkle density N5 is larger than the wrinkle density N2 of the inner peripheral ring 56. In addition, the smallest wrinkle density in the outer peripheral ring 57 is a value between the largest wrinkle density N3 and the smallest wrinkle density N4 in the lower turning connection portion 54.

  In the turning member 22, the light reflectance is lower as the grain density is higher, the light reflectance is higher as the grain density is lower, and the part where the light reflectance is higher appears brighter. Specifically, when light is applied to the turning member 22, the upper turning connection portion 53 looks darkest, and the outer peripheral ring 57 looks brighter as it approaches the front end. In this case, in the outer ring 57, a sense of depth that protrudes to the near side more than the protruding dimension from the upper facing connection portion 53 is created.

  The inner ring 56 looks brighter than the outer ring 57 due to its high light reflectivity, and has an effect of enhancing the appearance in relation to the sense of depth of the outer ring 57. Further, the lower turn-back connecting portion 54 can create a feeling of depth such that the lower end protrudes toward the front as compared with the upper end.

  The embossments 61 arranged in the facing ring portion 52 and the facing connection portions 53 and 54 are protrusions having the same size and shape. The embossing 61 of this embodiment is a pyramid, and the width dimension and the protrusion dimension are very small size of about 0.05 to 0.3 mm. Here, the embossing 61 arranged in the facing ring portion 52 will be described with reference to FIG.

  As shown in FIG. 4, the grain 61 extends in a direction orthogonal to the front surfaces 56 a and 57 a in each of the inner peripheral ring 56 and the outer peripheral ring 57. In this case, due to the front surfaces 56a and 57a intersecting each other, the extending direction L1 of the embossing 61 in the inner ring 56 and the extending direction L2 of the embossing 61 in the outer ring 57 intersect each other. Yes.

  In the vehicular display device 10, when the direction in which the display surface of the display plate 31 faces is referred to as a display direction L3, the opening angle A1 of the front surface 56a of the inner peripheral ring 56 with respect to the display direction L3, and the front surface 57a of the outer peripheral ring 57. The opening angle A2 with respect to is the same value. The display direction L3 is a direction orthogonal to the display plate 31.

  The grain 61 spans the bottom 62 extending along the front surfaces 56a and 57a of the rings 56 and 57, the top 63 spaced from the bottom 62 in the extending directions L1 and L2, and the peripheral edge and the top 63 of the bottom 62. And four side surfaces 64 formed. The grain 61 is a straight cone in which the extending directions L1 and L2 are orthogonal to the bottom 62, and the opening angle of the side surface 64 with respect to the extending directions L1 and L2 is the same on any of the four side surfaces 64. . Further, the opening angle B1 of the embossment 61 of the inner ring 56 and the opening angle B2 of the embossing 61 of the outer ring 57 are the same.

  The rising angle C1 of the side surface 64 of the embossing 61 with respect to the front surface 56a of the inner peripheral ring 56 and the rising angle C2 of the side surface 64 of the embossing 61 with respect to the front surface 57a of the outer peripheral ring 57 in the direction in which the rings 56 and 57 extend linearly. Are the same value. The rising angles C1 and C2 have the same values as the opening angles A1 and A2 of the front surfaces 56a and 57a of the rings 56 and 57 with respect to the display direction L3. Here, the texture 61 has four oblique sides which are boundaries between adjacent side surfaces 64, and among these oblique sides, the oblique sides extending backward from the top 63 extend in parallel with the display direction L3. .

  Here, a manufacturing method of the facing member 22 will be described. As shown in FIG. 5, first, in the step of forming the embossing 61, mold processing such as press processing or punch processing is performed using the mold 71. By performing this die machining, a large number of embossments 61 are applied to the facing member 22. Thereafter, a step of removing the mold 71 from the facing member 22 is performed. The mold 71 has a first mold 71a that is removed forward from the facing member 22 after the turning member 22 is processed, a second mold 71b that is removed rearward, and a third mold 71c that is removed laterally. doing.

  As shown in FIG. 6, the first mold 71 a has a large number of dimples 72. For this reason, when mold processing is performed using the mold 71, the resin material forming the turn-back member 22 enters each dimple 72, so that a large number of embossments 61 are formed. For this reason, the outer shape of the texture 61 is the same as the inner shape of the dimple 72. The first mold 71 a has a ring forming surface 73 that forms the return ring portion 52, and the dimple 72 is a recess that is recessed from the ring forming surface 73 toward the inside of the mold. In this case, the rising angles C <b> 1 and C <b> 2 of the side surface 64 of the texture 61 are the same as the recess angle D of the inner peripheral surface of the dimple 72 with respect to the ring forming surface 73.

  If the portion of the dimple 72 having the largest recess dimension, that is, the portion corresponding to the top portion 63 of the embossing 61 is referred to as a recess bottom portion 72a, the recess bottom portion 72a is exposed to the open side of the dimple 72 in the display direction L3. It will be. For this reason, when the removal direction of the first mold 71a coincides with the display direction L3 when the first mold 71a is removed from the turn ring portion 52, the top 63 of the embossing 61 is dimpled in the removal direction. 72 is not caught in the recess bottom 72a. Accordingly, it is possible to remove the first mold 71a from the counter ring part 52 without forcibly removing the first mold 71a. In this case, in the removal direction of the first mold 71a, the top 63 of the embossing 61 does not protrude beyond the bottom 62, and the embossing 61 has a shape that allows the first mold 71a to be removed. I can say that.

  In the present embodiment, the opening angles of the front surfaces 53a and 54a of the turning connection portions 53 and 54 with respect to the display direction L3 are larger than the opening angles A1 and A2 of the rings 56 and 57. In other words, in the turn-back connecting portions 53 and 54, the rising angle of the side surface 64 of the embossed 61 is smaller than the opening angle of the front surfaces 53a and 54a with respect to the display direction L3. For this reason, the embossed portion 61 of the reverse connection portion 53, 54 is prevented from being caught by the dimple 72 of the first mold 71a.

  Further, since the front surface 51a of the facing outer peripheral portion 51 is not provided with the texture 61, the front surface 51a of the facing outer peripheral portion 51 is caught by the first mold 71a regardless of the opening angle of the front surface 51a with respect to the display direction L3. It will not be.

  On the inner peripheral surface of the first mold 71a, the entire front surface 53a as a textured surface is matted by uniformly polishing the portion forming the front surface 53a of the upper facing connection portion 53. It is considered as a surface. On the other hand, the front surface 54a and the front surface 54a and the front surface 54a of the lower ring connection portion 54 and the front surface 57a of the outer peripheral ring 57 are gradually polished so that the front surfaces 54a and 57a as the embossed surfaces are matted. The gradation surface gradually shifts from the surface to the surface having gloss. In particular, on the front surface 57a of the outer peripheral ring 57, the matte effect by polishing the mold is gradually reduced as it approaches the front end surface. Further, the matting effect is uniformly reduced by lightly polishing the front surface 56a of the inner peripheral ring 56.

  Note that, on the inner peripheral surface of the first mold 71a, the mold polishing is not performed on the portion forming the front surface 51a of the facing outer peripheral portion 51. This is because black printing is performed on the front surface 51a.

  The operational effects of the first embodiment described so far will be described below.

  According to the first embodiment, a large number of embossments 61 are provided on the turning connection portions 53 and 54 and the rings 56 and 57 of the turning member 22. For this reason, the appearance of the display apparatus 10 for vehicles can be improved by combining the relative angle of each front surface 53a, 54a, 56a, 57a and the installation mode of the embossed 61. In addition, since a large number of embossments 61 are formed using the first mold 71a, the installation mode of the embossments 61 can be set finely. In this case, it can suppress that the installation aspect of the grain 61 becomes the state which is not intended, As a result, it can avoid that the appearance of the vehicle display apparatus 10 is impaired by the grain 61.

  In addition, since the crimp 61 has a shape that allows removal of the facing member 22 from the first mold 71a, it is not necessary to forcibly remove the first mold 71a. For this reason, when removing the first mold 71 a, it is possible to prevent the texture 61 from being caught by the dimple 72 and causing the top 63 and the side surface 64 of the texture 61 to be deformed or scraped. That is, it is possible to prevent the texture of the look-back member 22 from being unintended due to the irregular shape of the large number of embossments 61.

  According to the first embodiment, since the grain 61 is a cone, the grain 61 is less likely to be caught in the dimple 72 of the first mold 71a. For this reason, it is possible to suitably realize a configuration in which the embossment 61 has a shape that allows removal of the turning member 22 from the first mold 71a.

  According to the first embodiment, when the removal direction of the first mold 71a coincides with the display direction L3, the top 63 of the texture 61 does not protrude beyond the bottom 62. It is possible to realize a configuration that is difficult to catch on the dimple 72 of the mold 71a.

  According to the first embodiment, the rising angles C1, C2 of the embossments 61 of the inner ring 56 and the outer ring 57 are the same as the opening angles A1, A2 of the rings 56, 57 with respect to the removal direction of the first mold 71a. ing. For this reason, it is possible to realize a configuration in which the texture 61 is not caught in the dimple 72.

  According to the first embodiment, in the outer ring 57, the wrinkle density gradually decreases as it approaches the front end, so that the gradation effect due to the density of the installation manner of the wrinkles 61 can be imparted to the outer ring 57. it can. Here, since the light reflectance increases as the wrinkle density decreases, the light from the light emitting unit 41 through the indicator 32 of the display plate 31 or the light from the liquid crystal panel 15 through the protective plate 16 is transmitted to the outer peripheral ring 57. By hitting, the portion closer to the front end portion looks brighter. For this reason, in addition to the gradation effect obtained by visually recognizing a large number of the textures 61, the gradation effect due to the reflection of light by the texture 61 can provide a sense of depth and perspective of the outer ring 57. In addition, since a large number of embossments 61 are formed by mold processing, it is possible to suppress the gradation effect caused by these embossments 61 from being partially damaged unintentionally.

(Second embodiment)
As shown in FIG. 7, in the vehicle display device 10 of the second embodiment, the turn ring portion 52 is bent forward as in the vehicle display device 10 of the first embodiment. Instead, the return ring portion 52 is curved forward. In this case, a curved surface 52 a is included in the front surface of the facing ring portion 52, and the curved surface 52 a is a textured surface having a plurality of textured 61.

  The grain 61 is not a pyramid but a truncated pyramid. In the texture 61, the top 63 is an upper surface extending along the bottom 62. In this case, in the dimple 72 of the first mold 71 a, the hollow bottom portion 72 a is also a bottom surface corresponding to the top portion 63.

  In the texture 61 of the turning ring portion 52, the rising angle C <b> 3 of the side surface 64 is an angle between the tangent line L <b> 4 of the curved surface 52 a and the side surface 64 at the rising portion of the side surface 64. The rising angle C3 is smaller than the opening angle A3 of the tangent line L with respect to the display direction L3 when the removal direction of the first mold 71a coincides with the display direction L3. In this case, as in the first embodiment, the dimple bottom 72a of the dimple 72 is exposed on the open side of the dimple 72 in the display direction L3, so that the top 63 of the embossed 61 is caught inside the dimple 72. Don't be. Thus, even if the embossing 61 is provided on the curved surface 52a, it can be said that the embossing 61 has a shape that allows removal of the first mold 71a.

  According to the second embodiment, since a large number of embossments 61 are provided on the curved surface 52a of the facing ring portion 52, combining the curved surface 52a and the embedding mode of the embossed 61 allows the vehicle display device 10 to be It can enhance the appearance. In addition, since a large number of embossments 61 are formed using the first mold 71 a having a large number of dimples 72, the installation mode of the embossments 61 can be set finely. For this reason, it can avoid that the appearance of the display apparatus 10 for vehicles is impaired by the state which the installation aspect of the texture 61 becomes in an unintended state.

  According to the second embodiment, in the configuration in which the curved surface 52a is a textured surface, the opening angle A3 of the tangent line L4 of the curved surface 52a at the rising portion of the textured surface 61 is smaller than the textured rising angle C3. For example, the removal of the first mold 71 a is allowed by the embossing 61. For this reason, with respect to the curved surface 52a, by setting the rising angle C3 of the embossing 61 according to the portion where the opening angle of the tangent with respect to the removal direction is the largest, it is possible to realize a configuration in which the embossing 61 is not easily caught inside the dimple 72.

  According to the second embodiment, since the texture 61 is a truncated pyramid, the dimple 72 of the first mold 71a has a shape in which the resin material can easily enter. In this case, since the resin material does not properly enter the dimple 72 and the shape of the texture 61 is prevented from being uneven, a large number of texture 61 can be formed appropriately.

(Other embodiments)
Although a plurality of embodiments of the present invention have been described above, the present invention is not construed as being limited to these embodiments, and various embodiments and combinations can be made without departing from the scope of the present invention. Can be applied.

  In the first modification, the texture 61 may not be a pyramid as in the first embodiment, but may be a cone or a triangular pyramid. In short, if the texture 61 is a cone, it is possible to realize a configuration in which the texture 61 has a shape that allows removal of the facing member 22 from the first mold 71a.

  In the second modification, the pyramid texture 61 may not be a straight cone as in the first embodiment, but may be an oblique cone. For example, in the grain 61, the opening angles B1 and B2 of the side surface 64 with respect to the extending directions L1 and L2 are different for each side surface 64. In this configuration, it is preferable to arrange the embossment 61 in such a direction that the opening angles B1 and B2 of the side surfaces 64 extending rearward from the top 63 of the side surfaces 64 are the largest.

  In the third modification, the texture 61 may be a truncated cone or a triangular truncated cone instead of the truncated pyramid as in the second embodiment. In short, if the texture 61 is a frustum, it is possible to realize a configuration in which the resin material forming the facing member 22 can easily enter the dimple 72 properly. In this case, it is possible to appropriately form the texture 61 having a shape that can be easily removed from the dimple 72.

  In the modified example 4, the texture 61 may be a shape having a curved surface such as a hemispherical shape instead of a shape having a flat surface such as a cone or a frustum. For example, in the first embodiment, the rising angle of the tangent to the front surface 57a of the outer peripheral ring 57 is equal to or smaller than the opening angle of the front surface 57a with respect to the removal direction of the first mold 71a. And In this configuration, the rising portion of the embossing 61 is not caught by the dimple 72 of the first mold 71a. Thereby, the shape in which the embossing 61 permits the removal of the facing member 22 from the first mold 71a can be realized.

  In the modified example 5, the rising angle C1 of the embossing 61 of the inner ring 56 and the rising angle C2 of the embossing 61 of the outer ring 57 are not the same value as in the first embodiment, but these rising angles C1. , C2 may be different. Moreover, in the modification 6, unlike the first embodiment, the removal direction of the first mold 71a may not coincide with the display direction L3. In any of these modifications 5 and 6, if the rising angles C1 and C2 of the embossing 61 are less than the opening angles A1 and A2 of the front surfaces 56a and 57a of the rings 56 and 57 with respect to the removal direction of the first mold 71a. The removal of the first mold 71a is permitted by the embossing 61.

  In the modified example 7, the unevenness density of the lower facing connection portion 54 and the outer peripheral ring 57 is not made uneven as in the first embodiment, but this unevenness density is used for the upper facing connection portion 53 and the inner peripheral ring. Similarly to 56, it may be uniform.

  In the modified example 8, the front surface 51a of the facing outer peripheral portion 51 is not a textured surface as in the first embodiment, but the front surface 51a is a textured surface so that the entire front surface of the facing member 22 is a textured surface. Good. In this structure, since the part which needs black printing does not exist in the turning member 22, the process of performing black printing for matting in the manufacturing process of the turning member 22 can be abolished. As a result, it is possible to manufacture the facing member 22 that is a low-priced plate by the amount not subjected to black painting or black printing.

  In the modification 9, the turning member 22 does not have to surround the front spaces of the meters 11 and 12 and the intermediate display unit 13. In short, the facing member 22 should just partition this front space. Moreover, in the modification 10, the facing ring part 52 does not need to be annular shape. In short, it is sufficient that the facing ring portion 52 has a partition plate portion that partitions the front space of the meters 11 and 12.

  In the modified example 11, the facing member 22 is not formed by performing press working or punching using the mold 71, but is formed by performing injection molding using the mold 71. Also good. Even in this case, when the synthetic resin such as a thermoplastic resin enters the dimple 72, a large number of embossments 61 are formed on the turning member 22.

  In the modified example 12, the display device is not mounted on the vehicle as the vehicle display device 10, but the display device may be mounted on an airplane or a ship. In short, the display device may be anything that can be mounted on a moving body.
