（３） 前記支持リブは、前記径方向に沿う幅寸法が、前記天板部から前記リフレクタ部の底部に向かって次第に大きくされている、
ことを特徴とする上記（１）または（２）に記載のメータ装置。 (3) The width dimension of the support rib along the radial direction is gradually increased from the top plate portion toward the bottom portion of the reflector portion.

（４） 前記天板部には、前記文字板を係止する係止爪が形成されている、
ことを特徴とする上記（１）から（３）のいずれかに記載のメータ装置。 (4) A locking claw for locking the dial is formed on the top plate.
The meter device according to any one of (1) to (3) above.

上記（１）の構成のメータ装置によれば、リフレクタ部の中央に文字板を支持する文字板支持部を有するので、円形状の凹部からなるリフレクタ部を塞ぐように装着される文字板を、リフレクタ部の中央で良好に支持させることができる。これにより、リフレクタ部の中央で文字板を凹ませてしまうことなく、ケースへ文字板を円滑に装着させることができ、文字板の装着作業性を向上させることができる。
また、文字板支持部は、文字板が当接される円板状の天板部を、指針の基部を中心として径方向に沿って放射状に配置された複数の支持リブで支持している。これにより、指針の基部から照射される光を支持リブによって極力遮らずにリフレクタ部に導くことができ、リフレクタ部で反射した光によって輝度ムラを抑えつつ文字板を照らすことができる。また、文字板の裏面に沿って導光板を配置して複数の光源で導光板を光らせて文字板を照明させる構造と比較し、部品点数を削減してコストを抑えつつ文字板を輝度ムラなく照明することができる。 According to the meter device having the configuration of (1) above, since the dial supporting portion for supporting the dial is provided in the center of the reflector portion, the dial mounted so as to close the reflector portion formed of the circular recess is provided. It can be well supported at the center of the reflector portion. As a result, the dial can be smoothly mounted on the case without denting the dial at the center of the reflector portion, and the mounting workability of the dial can be improved.
Further, the dial support portion supports the disc-shaped top plate portion to which the dial is in contact with a plurality of support ribs radially arranged along the radial direction with the base of the pointer as the center. As a result, the light emitted from the base of the pointer can be guided to the reflector portion without being blocked by the support rib as much as possible, and the light reflected by the reflector portion can illuminate the dial while suppressing the uneven brightness. In addition, compared to a structure in which a light guide plate is placed along the back surface of the dial and the light guide plate is illuminated by multiple light sources to illuminate the dial, the number of parts is reduced to reduce costs and the dial is evenly brightened. Can be illuminated.

上記（２）の構成のメータ装置によれば、指針の基部から照射される光を、文字板と平行な環状溝部の底面と、この底面に対して垂直な周壁部とで反射させることにより、径方向の輝度ムラを抑えてさらに良好に文字板を照らすことができる。特に、環状溝部の底面に垂直な周壁部で反射して径方向内方へ向かう光によって、支持リブによって形成される影をぼかすことができる。 According to the meter device having the configuration of (2) above, the light emitted from the base of the pointer is reflected by the bottom surface of the annular groove portion parallel to the dial and the peripheral wall portion perpendicular to the bottom surface. It is possible to suppress uneven brightness in the radial direction and illuminate the dial even better. In particular, the shadow formed by the support ribs can be blurred by the light reflected inward in the radial direction by the peripheral wall portion perpendicular to the bottom surface of the annular groove portion.

上記（３）の構成のメータ装置によれば、支持リブの径方向に沿う幅寸法が、天板部からリフレクタ部の底部に向かって次第に大きくされている。これにより、支持リブの厚みを薄くして光の遮りを極力抑えつつ、支持リブの強度を高めて天板部を確実に支持させることができる。 According to the meter device having the configuration of (3) above, the width dimension along the radial direction of the support rib is gradually increased from the top plate portion to the bottom portion of the reflector portion. As a result, the thickness of the support rib can be reduced to suppress light blocking as much as possible, and the strength of the support rib can be increased to reliably support the top plate portion.

上記（４）の構成のメータ装置によれば、天板部に形成された係止爪を文字板に係止させることにより、リフレクタ部の中央において文字板を容易に天板部に保持させることができる。 According to the meter device having the configuration of (4) above, the dial is easily held by the top plate at the center of the reflector by locking the locking claws formed on the top plate to the dial. Can be done.

本発明によれば、構造の複雑化を抑えつつメータ周りの全域を３６０°に亘り輝度ムラなく均一に照明することが可能なメータ装置を提供できる。 According to the present invention, it is possible to provide a meter device capable of uniformly illuminating the entire area around the meter over 360 ° without uneven brightness while suppressing the complexity of the structure.

図５及び図６に示すように、リフレクタ部４１は、ケース２３の前面板部４２から後方へ凹む正面視円形状の凹部からなるもので、底壁部４４と、周壁部４５とを有している。底壁部４４の中央には、円形状の開口部４６が形成されている。 As shown in FIGS. 5 and 6, the reflector portion 41 is composed of a front view circular recess that is recessed rearward from the front plate portion 42 of the case 23, and has a bottom wall portion 44 and a peripheral wall portion 45. ing. A circular opening 46 is formed in the center of the bottom wall portion 44.

リフレクタ部４１には、その中央に、文字板支持部５１が設けられている。文字板支持部５１は、天板部５２と、天板部５２を支持する複数の支持リブ５３とを有している。天板部５２は、円板状に形成されており、底壁部４４に形成された開口部４６を臨む位置に配置されている。天板部５２には、その中央に指針３４の基部３５を通す挿通孔５５が形成されており、この挿通孔５５の縁部には、係止爪５６が形成されている。 The reflector portion 41 is provided with a dial support portion 51 in the center thereof. The dial support portion 51 has a top plate portion 52 and a plurality of support ribs 53 that support the top plate portion 52. The top plate portion 52 is formed in a disk shape, and is arranged at a position facing the opening 46 formed in the bottom wall portion 44. An insertion hole 55 through which the base portion 35 of the pointer 34 is passed is formed in the center of the top plate portion 52, and a locking claw 56 is formed at the edge of the insertion hole 55.

複数の支持リブ５３は、底壁部４４と天板部５２との間に設けられており、天板部５２は、支持リブ５３によって底壁部４４に支持されている。そして、これらの支持リブ５３によって底壁部４４に支持された天板部５２は、その表面がケース２３の前面板部４２と面一に配置されている。本例では、５つの支持リブ５３を有しており、これらの支持リブ５３が、底壁部４４の開口部４６に沿って周方向へ等間隔に配置されている。 A plurality of support ribs 53 are provided between the bottom wall portion 44 and the top plate portion 52, and the top plate portion 52 is supported by the bottom wall portion 44 by the support ribs 53. The surface of the top plate portion 52 supported by the bottom wall portion 44 by these support ribs 53 is arranged flush with the front plate portion 42 of the case 23. In this example, it has five support ribs 53, and these support ribs 53 are arranged at equal intervals in the circumferential direction along the opening 46 of the bottom wall portion 44.

支持リブ５３は、板状に形成されており、リフレクタ部４１の中心から放射状に沿って配置されている。支持リブ５３は、底壁部４４から立設されており、その上部が天板部５２に連結されている。天板部５２は、その周面に支持リブ５３の上部が連設されている。そして、これらの支持リブ５３は、側面視において天板部５２に連結された一端から底壁部４４に連結された他端へ向かって次第に幅寸法が広くなっている。これにより、支持リブ５３は、天板部５２に連結された一端から底壁部４４に連結された他端へ向かって次第に断面積が増加されている。 The support rib 53 is formed in a plate shape and is arranged radially from the center of the reflector portion 41. The support rib 53 is erected from the bottom wall portion 44, and the upper portion thereof is connected to the top plate portion 52. The upper portion of the support rib 53 is continuously provided on the peripheral surface of the top plate portion 52. The width of these support ribs 53 gradually increases from one end connected to the top plate 52 to the other end connected to the bottom wall 44 in a side view. As a result, the cross-sectional area of the support rib 53 is gradually increased from one end connected to the top plate portion 52 to the other end connected to the bottom wall portion 44.

支持リブ５３によって天板部５２が支持された文字板支持部５１では、底壁部４４と天板部５２との間に、支持リブ５３によって周方向に分割された複数の透光窓部５７が設けられている。 In the dial support portion 51 in which the top plate portion 52 is supported by the support rib 53, a plurality of translucent window portions 57 divided in the circumferential direction between the bottom wall portion 44 and the top plate portion 52 by the support rib 53. Is provided.

リフレクタ部４１の底壁部４４には、環状溝部６１が形成されている。この環状溝部６１は、周壁部４５と文字板支持部５１との間において環状に形成されている。この環状溝部６１は、その底面６２が平面になっており、径方向にわたって、前面板部４２に装着される文字板２４に対して平行になっている。これにより、この環状溝部６１は、その深さ寸法が径方向にわたって同一になっている。また、リフレクタ部４１の周壁部４５は、底壁部４４に形成された環状溝部６１の底面６２に対して垂直に形成されている。 An annular groove 61 is formed in the bottom wall 44 of the reflector 41. The annular groove portion 61 is formed in an annular shape between the peripheral wall portion 45 and the dial support portion 51. The bottom surface 62 of the annular groove portion 61 is flat, and is parallel to the dial 24 mounted on the front plate portion 42 in the radial direction. As a result, the annular groove portion 61 has the same depth dimension in the radial direction. Further, the peripheral wall portion 45 of the reflector portion 41 is formed perpendicular to the bottom surface 62 of the annular groove portion 61 formed in the bottom wall portion 44.

図１及び図２に示すように、ケース２３には、前面板部４２にシート状の文字板２４が重ね合わされて装着される。これにより、ケース２３は、リフレクタ部４１を含む前面の略全体が文字板２４によって覆われる。この文字板２４は、リフレクタ部４１の中央位置において、文字板支持部５１の天板部５２に当接されて支持される。また、文字板２４は、天板部５２に形成された係止爪５６によって天板部５２に当接された部分が係止される。 As shown in FIGS. 1 and 2, the case 23 is fitted with a sheet-shaped dial 24 superimposed on the front plate portion 42. As a result, substantially the entire front surface of the case 23 including the reflector portion 41 is covered with the dial 24. The dial 24 is supported by being abutted against the top plate portion 52 of the dial plate support portion 51 at the central position of the reflector portion 41. Further, the dial 24 is locked at a portion that is in contact with the top plate portion 52 by a locking claw 56 formed on the top plate portion 52.

文字板２４には、ケース２３のリフレクタ部４１を覆う位置に、車両速度やエンジン回転数を示す数字Ｎ及び目盛Ｍが設けられており、これらの数字Ｎ及び目盛Ｍでは、裏面からの光が透光可能となっている。目盛Ｍは、周方向にわたって繋がる環状に形成されている。文字板２４は、例えば、導光性を有する樹脂シートに対して、数字Ｎ及び目盛Ｍとなる部分等を除いて不透光性の遮光層を印刷して形成することにより得られる。 The dial 24 is provided with a number N and a scale M indicating the vehicle speed and the engine speed at a position covering the reflector portion 41 of the case 23. In these numbers N and the scale M, light from the back surface is emitted. It is translucent. The scale M is formed in an annular shape connecting in the circumferential direction. The dial 24 is obtained, for example, by printing a light-transmitting light-shielding layer on a resin sheet having a light-guiding property, except for a portion having a number N and a scale M.

図２に示すように、上記構造のメータ装置１０では、回転軸３３を介して指針３４内に導かれる光源３１からの光は、その一部の光Ｌ１が基部３５の反射面３８で反射し、針部３６側へ導かれ、これにより、針部３６が発光照明される。 As shown in FIG. 2, in the meter device 10 having the above structure, a part of the light L1 of the light L1 guided into the pointer 34 via the rotating shaft 33 is reflected by the reflecting surface 38 of the base 35. , The needle portion 36 is guided to the side of the needle portion 36, whereby the needle portion 36 is illuminated by light emission.

また、指針３４内に導かれた他の光Ｌ２は、基部３５の円錐反射面３９で反射し、回転軸３３の軸心を中心とした周囲に放射状に照射される。この放射状に照射される光Ｌ２は、透光窓部５７からケース２３のリフレクタ部４１内へ導かれる。リフレクタ部４１に導かれる光Ｌ２は、リフレクタ部４１の環状溝部６１の底面６２及びリフレクタ部４１の周壁部４５に反射して文字板２４に照射される。なお、リフレクタ部４１へ導かれた光Ｌ２には、リフレクタ部４１の環状溝部６１の底面６２で反射して文字板２４に照射される光、及び文字板２４を直接照射する光もある。 Further, the other light L2 guided in the pointer 34 is reflected by the conical reflecting surface 39 of the base 35, and is radiated around the axis of the rotating shaft 33. The light L2 emitted radially is guided from the translucent window portion 57 into the reflector portion 41 of the case 23. The light L2 guided to the reflector portion 41 is reflected by the bottom surface 62 of the annular groove portion 61 of the reflector portion 41 and the peripheral wall portion 45 of the reflector portion 41, and is irradiated to the dial 24. The light L2 guided to the reflector portion 41 includes light that is reflected by the bottom surface 62 of the annular groove portion 61 of the reflector portion 41 and is irradiated to the dial 24, and light that directly irradiates the dial 24.

ここで、指針３４の基部３５の周囲には、複数の支持リブ５３が設けられている。しかし、これらの支持リブ５３は、指針３４の基部３５を中心として径方向に沿って放射状に配置されている。したがって、指針３４の基部３５から照射される光Ｌ２は、支持リブ５３によって極力遮られずにリフレクタ部４１へ全周にわたって導かれることとなる。 Here, a plurality of support ribs 53 are provided around the base 35 of the pointer 34. However, these support ribs 53 are arranged radially along the radial direction about the base 35 of the pointer 34. Therefore, the light L2 emitted from the base 35 of the pointer 34 is guided to the reflector portion 41 over the entire circumference without being blocked by the support rib 53 as much as possible.

以上、説明したように、本実施形態に係るメータ装置１０によれば、リフレクタ部４１の中央に文字板２４を支持する文字板支持部５１を有するので、円形状の凹部からなるリフレクタ部４１を塞ぐように装着される文字板２４を、リフレクタ部４１の中央で良好に支持させることができる。これにより、リフレクタ部４１の中央で文字板２４を凹ませてしまうことなく、ケース２３へ文字板２４を円滑に装着させることができ、文字板２４の装着作業性を向上させることができる。 As described above, according to the meter device 10 according to the present embodiment, since the dial support portion 51 that supports the dial 24 is provided in the center of the reflector portion 41, the reflector portion 41 formed of a circular recess is provided. The dial 24, which is mounted so as to be closed, can be satisfactorily supported at the center of the reflector portion 41. As a result, the dial 24 can be smoothly mounted on the case 23 without denting the dial 24 at the center of the reflector portion 41, and the mounting workability of the dial 24 can be improved.

また、文字板支持部５１は、文字板２４が当接される円板状の天板部５２を、指針３４の基部３５を中心として径方向に沿って放射状に配置された複数の支持リブ５３で支持している。これにより、指針３４の基部３５から照射される光Ｌ２を支持リブ５３によって極力遮らずにリフレクタ部４１に導くことができ、リフレクタ部４１で反射した光Ｌ２によって輝度ムラを抑えつつ文字板２４を照らすことができる。また、文字板の裏面に沿って導光板を配置して複数の光源で導光板を光らせて文字板を照明させる構造と比較し、部品点数を削減してコストを抑えつつ文字板をムーブメント３２の回転軸３３に対し３６０°輝度ムラなく照明することができる。 Further, the dial support portion 51 has a plurality of support ribs 53 in which the disk-shaped top plate portion 52 with which the dial 24 is in contact is radially arranged along the radial direction with the base portion 35 of the pointer 34 as the center. It is supported by. As a result, the light L2 emitted from the base 35 of the pointer 34 can be guided to the reflector portion 41 without being blocked by the support rib 53 as much as possible, and the dial 24 is suppressed by the light L2 reflected by the reflector portion 41 while suppressing the uneven brightness. Can illuminate. Further, as compared with the structure in which the light guide plate is arranged along the back surface of the dial and the light guide plate is illuminated by a plurality of light sources to illuminate the dial, the number of parts is reduced and the cost is reduced while the dial is moved to the movement 32. It is possible to illuminate the rotating shaft 33 at 360 ° without uneven brightness.

ここで、リフレクタ部４１の環状溝部６１を外周にいくほど浅くすると、外周部分で輝度を高めることができるが、支持リブ５３の影が出やすくなる。逆にリフレクタ部４１の環状溝部６１を外周にいくほど深くすると、外周部分の輝度が低下する。 Here, if the annular groove portion 61 of the reflector portion 41 is made shallower toward the outer circumference, the brightness can be increased at the outer peripheral portion, but the shadow of the support rib 53 is likely to appear. On the contrary, when the annular groove portion 61 of the reflector portion 41 is deepened toward the outer circumference, the brightness of the outer peripheral portion is lowered.

本実施形態に係るメータ装置１０では、リフレクタ部４１の底部における文字板支持部５１の周囲に、文字板２４と平行な底面６２を有する環状溝部６１が形成されている。したがって、メータ装置１０によれば、指針３４の基部３５から照射される光Ｌ２を、文字板２４と平行な環状溝部６１の底面６２と、この底面６２に対して垂直な周壁部４５とで反射させることにより、径方向の輝度ムラを抑えてさらに良好に文字板２４を照らすことができる。 In the meter device 10 according to the present embodiment, an annular groove portion 61 having a bottom surface 62 parallel to the dial 24 is formed around the dial plate support portion 51 at the bottom portion of the reflector portion 41. Therefore, according to the meter device 10, the light L2 emitted from the base 35 of the pointer 34 is reflected by the bottom surface 62 of the annular groove 61 parallel to the dial 24 and the peripheral wall 45 perpendicular to the bottom surface 62. By doing so, it is possible to suppress the uneven brightness in the radial direction and illuminate the dial 24 more satisfactorily.

また、リフレクタ部４１は、環状溝部６１の底面６２に対して垂直な周壁部４５を有しているので、この環状溝部６１の底面６２に垂直な周壁部４５で反射して径方向内方へ向かう光Ｌ２によって、支持リブ５３によって形成される影をぼかすことができる。 Further, since the reflector portion 41 has a peripheral wall portion 45 perpendicular to the bottom surface 62 of the annular groove portion 61, the reflector portion 41 is reflected by the peripheral wall portion 45 perpendicular to the bottom surface 62 of the annular groove portion 61 and is reflected inward in the radial direction. The directed light L2 can blur the shadow formed by the support rib 53.

また、本実施形態に係るメータ装置１０によれば、支持リブ５３は、指針３４の基部３５を中心として径方向に沿う幅寸法が、天板部５２からリフレクタ部４１の底部に向かって次第に大きくされているので、支持リブ５３の厚みを薄くして光Ｌ２の遮りを極力抑えつつ、支持リブ５３の強度を高めて天板部５２を確実に支持させることができる。 Further, according to the meter device 10 according to the present embodiment, the width dimension of the support rib 53 along the radial direction about the base 35 of the pointer 34 gradually increases from the top plate portion 52 toward the bottom portion of the reflector portion 41. Therefore, the thickness of the support rib 53 can be reduced to suppress the obstruction of the light L2 as much as possible, and the strength of the support rib 53 can be increased to reliably support the top plate portion 52.

しかも、天板部５２に形成された係止爪５６を文字板２４に係止させることにより、リフレクタ部４１の中央において文字板２４を容易に天板部５２に保持させることができる。 Moreover, by locking the locking claw 56 formed on the top plate portion 52 to the dial portion 24, the dial plate 24 can be easily held by the top plate portion 52 at the center of the reflector portion 41.

次に、リフレクタ部の参考例について説明する。
図７は、参考例に係るリフレクタ部の斜視図である。
図７に示すように、参考例に係るリフレクタ部７１では、発光ダイオード等の表示灯が装着される複数の装着孔７２を有するインジケータ部７３が張り出している。そして、このインジケータ部７３に文字板を係止する係止爪７４が形成されている。また、このリフレクタ部７１では、底面７５が、径方向外方へ向かって次第に手前に傾斜されている。 Next, a reference example of the reflector unit will be described.
FIG. 7 is a perspective view of the reflector portion according to the reference example.
As shown in FIG. 7, in the reflector unit 71 according to the reference example, an indicator unit 73 having a plurality of mounting holes 72 for mounting indicator lights such as light emitting diodes is projected. A locking claw 74 for locking the dial is formed on the indicator portion 73. Further, in the reflector portion 71, the bottom surface 75 is gradually inclined toward the outside in the radial direction.

この参考例では、リフレクタ部７１にインジケータ部７３が張り出しているため、リフレクタ部７１における周方向全域に光を照射させることができない。このため、照明範囲が狭くなり、照明による効果が制限されてしまう。また、参考例では、リフレクタ部７１の底面７５が、径方向外方へ向かって次第に手前に傾斜されているので、文字板を照射する光が径方向に均一とならず、輝度ムラが生じてしまう。 In this reference example, since the indicator portion 73 projects from the reflector portion 71, it is not possible to irradiate the entire circumferential direction of the reflector portion 71 with light. Therefore, the illumination range is narrowed, and the effect of illumination is limited. Further, in the reference example, since the bottom surface 75 of the reflector portion 71 is gradually inclined toward the outside in the radial direction, the light irradiating the dial is not uniform in the radial direction, resulting in uneven brightness. It ends up.

尚、本発明は、上述した実施形態に限定されるものではなく、適宜、変形、改良、等が可能である。その他、上述した実施形態における各構成要素の材質、形状、寸法、数、配置箇所、等は本発明を達成できるものであれば任意であり、限定されない。 The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, and the like. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

例えば、上記実施形態では、５つの支持リブ５３を設けた場合を例示したが、支持リブ５３の数は複数であれば５つに限定されない。なお、支持リブ５３の数は５つが最適であり、５つの支持リブ５３を設けることにより、遮光を抑えつつ天板部５２を良好に支持することができる。 For example, in the above embodiment, the case where five support ribs 53 are provided is illustrated, but the number of support ribs 53 is not limited to five as long as it is plural. The optimum number of support ribs 53 is five, and by providing the five support ribs 53, the top plate portion 52 can be satisfactorily supported while suppressing light shielding.

また、上記実施形態では、天板部５２に設けた係止爪５６によって文字板２４を係止させる構造としたが、他の固定方法によって天板部５２へ文字板２４を固定してもよい。例えば、他の固定方法としては、天板部５２に対して接着材によって文字板２４を接着固定する方法などがある。 Further, in the above embodiment, the dial 24 is locked by the locking claw 56 provided on the top plate 52, but the dial 24 may be fixed to the top 52 by another fixing method. .. For example, as another fixing method, there is a method of adhesively fixing the dial 24 to the top plate portion 52 with an adhesive.

また、上記実施形態では、１枚の文字板２４によって２つのリフレクタ部４１を覆って２つのメータ部１１を構成したが、２枚の文字板２４によって２つのリフレクタ部４１をそれぞれ覆う構造としてもよい。なお、１枚の文字板２４によって２つのリフレクタ部４１を覆う構造であれば、文字板２４の数を削減して低コスト化できる。 Further, in the above embodiment, one dial 24 covers the two reflector portions 41 to form two meter portions 11, but the two dials 24 may cover the two reflector portions 41, respectively. Good. If the structure is such that one dial 24 covers the two reflectors 41, the number of dials 24 can be reduced and the cost can be reduced.
