A second reflecting surface (reflecting surface) 72 a that reflects light from the first reflecting surface 71 c on the side of the first pointer portion 71 toward the distal end side of the pointing portion 75 is provided. Note that the end surface of the second joint end portion 76 (the end surface facing the first joint end portion 74) is set to be substantially flat in order to suppress irregular reflection and diffuse reflection of light, similarly to the end surface of the first joint end portion 74. ing.

連結部材７３は、例えば白色からなる反射色を有する遮光性合成樹脂材料からなり、第１，第２の接合端部７４，７６の外周を取り巻くと共に各接合端部７４，７６の延長方向に沿って開口する筒状の接合部７３１と、第２の反射面７２ａの外側を覆い、光の抜けを防止する反射壁部７３２とを有している。   The connecting member 73 is made of, for example, a light-shielding synthetic resin material having a reflection color composed of white, surrounds the outer periphery of the first and second joint end portions 74 and 76 and extends in the extending direction of the joint end portions 74 and 76. A cylindrical joining portion 731 that opens and a reflecting wall portion 732 that covers the outside of the second reflecting surface 72a and prevents light from being lost.

ここで組み付け例を説明すると、まず第１の指針部７１を駆動軸に連結し、その前方に支持体２配置し、その前方に表示パネル１２、表示板１１の順で配置する。次に予め接合部７３１の上半分領域内に第２の接合端部７６を挿入して第２の指針部７２と連結しておいた接合部材７３の接合部７３１の下半分領域を、第１の指針部７１の第２の接合端部７４に挿入し、規制部７４ａに当接させることにより、各指針部７１，７２の接合が完了する。 Here, the assembly example will be described. First, the first pointer portion 71 is connected to the drive shaft, the support body 2 is arranged in front of it, and the display panel 12 and the display plate 11 are arranged in that order in that order. The lower half area of the junction 731 of the joint member 73 then that had been connected second and pointer part 7 2 by inserting the second connecting end 76 on the half region of the pre-joint 731, the 1 is inserted into the pointer unit 71 of the second connecting end 7 4, by contacting the restricting portion 74a, the junction of the hands 71, 72 is completed.

なお接合部７３１の上半分領域内に第２の接合端部７６を挿入する場合は、接合部７３１の上側を覆う反射壁部７３２を接合部７３１を構成する壁面と平行になる程度に弾性変形させた後に挿入するようにしており、挿入後、反射壁部７３２はその弾性力により元の位置（形状）に戻るものである。   In addition, when inserting the 2nd junction edge part 76 in the upper half area | region of the junction part 731, it elastically deforms so that the reflective wall part 732 which covers the upper side of the junction part 731 may become parallel to the wall surface which comprises the junction part 731. After the insertion, the reflection wall portion 732 returns to its original position (shape) by its elastic force.

ここで、第１，第２の接合端部７４，７６と、連結部材７３の接合部７３１の形状は、それぞれ断面多角形状（この場合四角形状）に設定され、第１，第２の指針部７１，７２が各接合端部７４，７６の延長方向を軸として回転するのを抑制している。すなわち、連結部材７３に対して各指針部７１，７２が回転不能に設定されている。なお各指針部７１，７２の回転を規制する手段としては、様々な形状設定が考えられ、例えば各指針部７１，７２の各接合端部７４，７６と接合部７３１の各形状を断面「Ｄ」字型に設定してもよいし、各接合端部７４，７６と接合部７３１の各外形状を断面正円形状とし、各接合端部７４，７６のうち、一方に断面多角形または「Ｄ」字型の孔部を形成し、他方にこの孔部に嵌合する角柱または断面「Ｄ」字柱を形成して回転規制を行ってもよく、回転規制可能であれば、任意の構成を採用することができる。   Here, the first and second joint end portions 74 and 76 and the shape of the joint portion 731 of the connecting member 73 are each set to have a polygonal cross section (in this case, a quadrangular shape), and the first and second pointer portions. 71 and 72 are prevented from rotating about the extension direction of each joint end part 74 and 76 as an axis. That is, the pointer portions 71 and 72 are set so as not to rotate with respect to the connecting member 73. As a means for restricting the rotation of the pointer parts 71 and 72, various shape settings are conceivable. The outer shape of each joint end portion 74, 76 and the joint portion 731 may be a circular shape in cross section, and one of the joint end portions 74, 76 may have a cross section polygon or “ D ”-shaped hole portion may be formed on the other side, and a rectangular column or a cross-sectional“ D ”-shaped column fitted into this hole portion may be formed on the other side to restrict rotation. Can be adopted.

隠蔽部材８は、例えば黒色の遮光性合成樹脂からなり、指針６と表示部材１の所要部を露出する開口部８１を有し、その他の領域（観察者に見せる必要のない不要部）は、隠蔽するものである。   The concealing member 8 is made of, for example, black light-shielding synthetic resin, has an opening 81 that exposes the pointer 6 and a required portion of the display member 1, and other regions (unnecessary portions that need not be shown to the observer) are: It is something to hide.

以上の通り、本実施形態では、表示部材１と、この表示部材１の背後に配置され駆動軸３を有する駆動装置４と、駆動軸３に連結され表示部材１に沿って軸周り回動する指針７と、この指針７を照明する光源５とを備えており、指針７が表示部材１の背後に位置し観察者から視認されない第１の指針部７１と表示部材１上に位置し観察者から視認される第２の指針部７２とに分割形成された光透過性材料からなり、第１の指針部７１と第２の指針部７２とが遮光性材料からなる連結部材７３を介して接合されることにより、第１の指針部７１と第２の指針部７２との接合面からの光漏れを抑制でき、これにより指針を分割形成する場合でも照明効率の低下を抑制することができる。また連結部材７３を用いて各指針部７１，７２どうしを接合する構造であるため、各接続端部７４，７６の接合面の形状を可能な限り単純化（この例では平滑平面化）して、光の乱反射や拡散を抑えることができる。この結果、照明効率の低下を抑制しながら、両指針部７１，７２どうしの接合強度を高めることができる。   As described above, in the present embodiment, the display member 1, the drive device 4 having the drive shaft 3 disposed behind the display member 1, and the shaft connected to the drive shaft 3 and rotating about the axis along the display member 1. A pointer 7 and a light source 5 that illuminates the pointer 7 are provided. The pointer 7 is located behind the display member 1 and is not visible to the observer, and is positioned on the display member 1 and the observer. It consists of the light-transmitting material dividedly formed in the 2nd pointer part 72 visually recognized from 1st, and the 1st pointer part 71 and the 2nd pointer part 72 are joined via the connection member 73 which consists of a light-shielding material. By doing so, it is possible to suppress light leakage from the joint surface between the first pointer portion 71 and the second pointer portion 72, thereby suppressing a decrease in illumination efficiency even when the pointer is dividedly formed. In addition, since the structure is such that the pointer parts 71 and 72 are joined together using the connecting member 73, the shape of the joint surface of each connection end part 74 and 76 is simplified as much as possible (in this example, the smooth flat surface). , Light reflection and diffusion can be suppressed. As a result, it is possible to increase the bonding strength between the pointer parts 71 and 72 while suppressing a decrease in illumination efficiency.
