Description

本発明は、例えば自動車を代表とする車両に搭載される指針式計器に関し、特に指針の仮想回転中心を含む中央領域に表示装置などを備えた指針式計器に関する。 The present invention relates to a pointer-type instrument mounted on a vehicle represented by, for example, an automobile, and more particularly to a pointer-type instrument provided with a display device or the like in a central region including a virtual rotation center of a pointer.

従来、指針式計器は、指針の仮想回転中心を含む中央領域に表示装置などを備え、この表示装置を取り囲むように環状の指標板を備えている。この環状の指標板の背後に、外周にギヤ列が設けられたリング形の移動部材（合成樹脂製）を設け、この移動部材に指針を設けると共にギヤ列に噛み合う回転歯車を連結し、この回転歯車をモータ等の駆動装置を通じて回転させることにより前記移動部材を回転駆動して前記指針による前記指標部の指示を行わせる構成を採用している。前記移動部材の支持は、前記移動部材の外周を支持するよう回転方向に間隔を空けて配置される支持部材によって行われる。この支持部材は位置が変化しない不動の固定支持部材（位置不動ローラ）と、前記移動部材に追従して位置が変化する押圧支持部材（位置移動ローラ）とからなり、この押圧支持部材が前記移動部材（前記移動部材の形状変化）に追従して前記移動部材を押圧するように構成することで、前記指針と前記指標板との位置関係を正確に保つようにしている（例えば、下記特許文献１参照）。
特開２００４−３６１１８２号公報（図５） Conventionally, the pointer-type instrument is provided with a display device or the like in a central region including the virtual rotation center of the pointer, and an annular indicator plate so as to surround the display device. A ring-shaped moving member (made of synthetic resin) with a gear train provided on the outer periphery is provided behind the annular indicator plate, a pointer is provided on the moving member, and a rotating gear that meshes with the gear train is connected to the rotating member. A configuration is adopted in which the moving member is rotated by rotating a gear through a driving device such as a motor so that the indicator portion is instructed by the pointer. The moving member is supported by supporting members that are spaced apart in the rotational direction so as to support the outer periphery of the moving member. The support member includes an immovable fixed support member (position immovable roller) whose position does not change, and a pressure support member (position movement roller) whose position changes following the moving member. By following the member (change in shape of the moving member) and pressing the moving member, the positional relationship between the pointer and the indicator plate is accurately maintained (for example, the following patent document) 1).
Japanese Patent Laying-Open No. 2004-361182 (FIG. 5)

しかしながら、従来の指針式計器では、前記リング形の移動部材は、部品加工の精度によって完全な真円を得ることは難しく、また、前記固定支持部材も同様に完全な真円に配置することは困難であるため、前記移動部材と前記固定支持部材との間に間隙が発生することを、前記移動部材に追従して位置が変化する前記押圧支持部材を設けることによって防止していた。 However, in the conventional pointer-type measuring instrument, it is difficult to obtain a complete perfect circle for the ring-shaped moving member due to the accuracy of parts processing, and it is also impossible to arrange the fixed support member in a perfect perfect circle as well. Since it is difficult, the generation of a gap between the moving member and the fixed support member is prevented by providing the pressing support member whose position changes following the moving member.

しかし、前記押圧支持部材を設けても、前記移動部材を前記駆動装置によって回転させることによって前記移動部材の円形が変形し、前記移動部材と前記固定支持部材との接触する圧力が低下することは防ぐことができず、この移動部材と固定支持部材との接触する圧力の低下によって、前記固定支持部材を構成するローラを押さえつけていた圧力が低下する。この圧力の低下によって、前記ローラが振動し、この振動が振動音などの発生の原因となる虞があった。 However, even if the pressing support member is provided, by rotating the moving member by the driving device, the circular shape of the moving member is deformed, and the pressure of contact between the moving member and the fixed support member is reduced. It cannot be prevented, and the pressure which pressed the roller which comprises the said fixed support member falls by the fall of the pressure which this moving member and a fixed support member contact. Due to the decrease in pressure, the roller vibrates, and this vibration may cause generation of vibration noise.

特に、前記ローラを備えた前記固定支持部材と、前記駆動装置とを共通のケースなどに設けてある場合は、前記駆動装置の振動が前記固定支持部材の前記ローラに伝わり、振動音を発生する虞があった。 In particular, when the fixed support member provided with the roller and the drive device are provided in a common case or the like, vibration of the drive device is transmitted to the roller of the fixed support member to generate vibration sound. There was a fear.

そこで本発明は、前述の課題に対して対処するため、振動音の発生を抑制することが可能な指針式計器を提供することを目的とするものである。 Accordingly, an object of the present invention is to provide a pointer-type instrument capable of suppressing the generation of vibration noise in order to cope with the above-described problems.

以下、図面に基づいて本発明による指針式計器の実施例について説明する。 Embodiments of a pointer-type instrument according to the present invention will be described below with reference to the drawings.

指針式計器は、図１、図２に示すように、指標板１と、この指標板１の背後に配置される環状移動部材２と、この環状移動部材２に装着される指針３と、環状移動部材２の背後に配置されるフレーム部材４と、環状移動部材２を回転移動させる駆動装置５と、観察者に所定情報を表示する表示装置６とを備えている。 As shown in FIGS. 1 and 2, the pointer-type instrument includes an indicator plate 1, an annular moving member 2 disposed behind the indicator plate 1, an indicator 3 attached to the annular moving member 2, an annular shape A frame member 4 disposed behind the moving member 2, a driving device 5 that rotates and moves the annular moving member 2, and a display device 6 that displays predetermined information to an observer.

指標板１は、略中央領域に左右の２辺が円弧の変形四角形の貫通孔からなる透視部１１を有し、この透視部１１の外周には、指針３の移動経路に沿って円弧状に配列された文字や目盛等の指標部１２を備えている。これら指標部１２は、指標板１を構成する合成樹脂板からなる基材上にスクリーン印刷等の手段により形成されている。 The indicator plate 1 has a see-through portion 11 formed of a deformed quadrilateral through-hole having two arcuate arcs in the left and right sides in a substantially central region, and the outer periphery of the see-through portion 11 has an arc shape along the movement path of the pointer 3 An indicator portion 12 such as arranged characters and scales is provided. These indicator portions 12 are formed on a substrate made of a synthetic resin plate constituting the indicator plate 1 by means such as screen printing.

環状移動部材２は合成樹脂からなり、閉じられたリング形状に形成されている。その内周には駆動装置５を通じて駆動される後述する回転部材に噛み合うギヤ列（第１のギヤ列）２１と、後述する支持部材に接触する接触部２２とがそれぞれ形成されており（図３も参照）、本例の場合、ギヤ列２１は接触部２２よりも背後（フレーム部材４）側で内側に突出するように設けられている。 The annular moving member 2 is made of synthetic resin and is formed in a closed ring shape. A gear train (first gear train) 21 that meshes with a rotating member (described later) driven through the driving device 5 and a contact portion 22 that contacts a supporting member (described later) are formed on the inner periphery (FIG. 3). In the case of this example, the gear train 21 is provided so as to protrude inward on the back side (frame member 4) side of the contact portion 22.

指針３は合成樹脂からなり、線状に形成されている。そして、その先端が環状移動部材２の回転中心側を向くように環状移動部材２に装着固定され、環状移動部材２と共に回動して指標部１２を指示する。 The pointer 3 is made of a synthetic resin and is formed in a linear shape. And it mounts and is fixed to the annular moving member 2 so that the tip thereof faces the rotation center side of the annular moving member 2, and rotates together with the annular moving member 2 to indicate the indicator portion 12.

フレーム部材４は金属からなり、例えば指標板１の透視部１１及び表示装置６に対応する貫通部４１を有する概略環状の形状である。このフレーム部材４の周辺部には、環状移動部材２の底部を点接触にて受ける突起状のスラスト受部４２（図３、図４も参照）が設けられている。スラスト受部４２は合成樹脂からなり、例えばアウトサートまたはインサート成形によって、フレーム部材４に形成されている。また、フレーム部材４は、支持部材を備えており、この支持部材は、環状移動部材２の内周に接して支持するよう回転方向に間隔を空けて配置されてある。支持部材は、第１の支持部材４３と第２の支持部材４４の２種類からなる。本実施例では、後述する回転部材と第１の支持部材４３との間に、第２の支持部材４４を配置している。また、第１の支持部材４３を隣り合うように２つ設けてある。よって、本実施例においては、後述する一つの回転部材と、二つの第１の支持部材４３及び二つの第２の支持部材４４の合計５つの部材によって、環状移動部材２を支持している。各部材間の間隔は、７２度ずつであり、各部材間の間隔が均等になるように設けられている。 The frame member 4 is made of metal and has, for example, a substantially annular shape having a see-through portion 11 of the indicator plate 1 and a through portion 41 corresponding to the display device 6. On the periphery of the frame member 4, a protruding thrust receiving portion 42 (see also FIGS. 3 and 4) that receives the bottom portion of the annular moving member 2 by point contact is provided. The thrust receiving portion 42 is made of a synthetic resin and is formed on the frame member 4 by, for example, outsert or insert molding. Further, the frame member 4 includes a support member, and the support members are arranged at intervals in the rotation direction so as to be in contact with and support the inner periphery of the annular moving member 2. The support member consists of two types, a first support member 43 and a second support member 44. In the present embodiment, a second support member 44 is disposed between the rotating member described later and the first support member 43. In addition, two first support members 43 are provided adjacent to each other. Therefore, in the present embodiment, the annular moving member 2 is supported by a total of five members including one rotating member, which will be described later, and two first support members 43 and two second support members 44. The interval between each member is 72 degrees, and the interval between each member is provided to be equal.

第１の支持部材４３は、図２、図３にも示すように、軸部材４３１と、この軸部材４３１を軸として回動可能に設けられる支持体４３２と、この支持体４３２に設けた軸４３３に回転可能に設けられる回転体４３４と、この回転体４３４を環状移動部材２側に押圧するように支持体４３２を付勢するコイルバネなどの付勢部材４３５とからなる。なお、支持体４３２の可動範囲は、環状移動部材２の正規の位置よりも回転中心から外側（外周）方向に移動可能であるとともに、環状移動部材２の正規の位置よりも回転中心側（内周）方向に移動可能であり、第１の支持部材４３は、環状移動部材２との接触部材、本実施例においては、回転体４３４が環状移動部材２の内周外周両方向に移動可能である（図２の矢印を参照）。 As shown in FIGS. 2 and 3, the first support member 43 includes a shaft member 431, a support body 432 that can be rotated about the shaft member 431, and a shaft provided on the support body 432. Rotating body 434 provided rotatably on 433, and a biasing member 435 such as a coil spring that biases support body 432 so as to press this rotating body 434 toward the annular moving member 2 side. The movable range of the support 432 is movable from the rotation center to the outer side (outer circumference) direction from the normal position of the annular moving member 2, and at the rotation center side (inner side) from the normal position of the annular movement member 2. The first support member 43 is a contact member with the annular moving member 2. In this embodiment, the rotating body 434 is movable in both directions of the inner and outer circumferences of the annular moving member 2. (See arrow in FIG. 2).

なお、軸部材４３１は金属材料からなり、フレーム部材４に固定されている。また、回転体４３４は、その外周面が環状移動部材２の接触部２２に接触し、環状移動部材２の移動に伴って回転するものである。図３にて詳しく示すように、回転体４３４の外周面は曲面に、接触部２２は傾斜面に設定され、両者が点接触するように構成されている。 The shaft member 431 is made of a metal material and is fixed to the frame member 4. Further, the outer peripheral surface of the rotating body 434 comes into contact with the contact portion 22 of the annular moving member 2 and rotates as the annular moving member 2 moves. As shown in detail in FIG. 3, the outer peripheral surface of the rotating body 434 is set to a curved surface, and the contact portion 22 is set to an inclined surface, and both are configured to be in point contact.

第２の支持部材４４は、支持体４４２の可動範囲以外は、第１の支持部材４３と同一構造である。第２の支持部材４４も、軸部材４４１、支持体４４２、軸４４３、回転体４４４及び図示しないバネなどの付勢部材とからなる。第２の支持部材４４の前記付勢部材の付勢する力は、第１の支持部材４３の付勢部材４３５の付勢する力より小さく設定されている。第２の支持部材４４の可動範囲は、環状移動部材２の正規の位置よりも回転中心から外側（外周）方向にのみ移動可能であるが、環状移動部材２の正規の位置よりも回転中心側（内周）方向に移動不可能である。第２の支持部材４４は、環状移動部材２との接触部材、本実施例においては、回転体４４４が環状移動部材２の外周方向にのみ移動可能である（図２の矢印を参照）。 The second support member 44 has the same structure as the first support member 43 except for the movable range of the support body 442. The second support member 44 also includes a shaft member 441, a support body 442, a shaft 443, a rotating body 444, and a biasing member such as a spring (not shown). The biasing force of the biasing member of the second support member 44 is set smaller than the biasing force of the biasing member 435 of the first support member 43. The movable range of the second support member 44 is movable only in the outer (outer peripheral) direction from the rotation center than the normal position of the annular moving member 2, but the rotation center side of the normal position of the annular movement member 2. It cannot move in the (inner circumference) direction. The second support member 44 is a contact member with the annular moving member 2, and in this embodiment, the rotating body 444 is movable only in the outer peripheral direction of the annular moving member 2 (see the arrow in FIG. 2).

駆動装置５は、例えばステッピングモータからなり、駆動軸５１がフレーム部材４を通して前方に延びており、回転部材５２を備えている。 The drive device 5 is formed of a stepping motor, for example, and a drive shaft 51 extends forward through the frame member 4 and includes a rotation member 52.

回転部材５２は合成樹脂からなり、その外周に環状移動部材２のギヤ列２１に噛み合うギヤ列（第２のギヤ列）５３を有し、駆動軸５１と共に回転するよう固定されている。規制手段５４は、回転部材５２に一体設けられ、ギヤ列５３形成部分の外径よりも大きく形成され、環状移動部材２の接触部２２に接触し、各ギヤ列２１，５３の噛み合い深さを規制することで、各ギヤ列２１，５３の噛み合い深さが深くなり過ぎ、駆動装置５に過大な負荷がかかったり、各ギヤ列２１，５３がロックすることを防止することができる。なお規制手段５４の形状（断面形状）は、接触部２２と線接触するようの曲面に設定されている。なお、本実施例では、回転部材５２と、規制手段５４とを同一部品としたが、別部品としてもよい。 The rotating member 52 is made of synthetic resin, and has a gear train (second gear train) 53 that meshes with the gear train 21 of the annular moving member 2 on the outer periphery thereof, and is fixed so as to rotate together with the drive shaft 51. The restricting means 54 is provided integrally with the rotating member 52, is formed larger than the outer diameter of the gear train 53 forming portion, contacts the contact portion 22 of the annular moving member 2, and sets the meshing depth of the gear trains 21, 53. By restricting, it is possible to prevent the meshing depth of the gear trains 21 and 53 from becoming excessively deep, so that an excessive load is applied to the drive device 5 and the gear trains 21 and 53 are locked. The shape (cross-sectional shape) of the regulating means 54 is set to a curved surface so as to be in line contact with the contact portion 22. In the present embodiment, the rotating member 52 and the regulating means 54 are the same part, but they may be separate parts.

表示装置６は、例えば液晶表示装置からなり、指標板１の透視部１１に臨むように設けられており、例えば走行距離データや外気温データからなる計測情報やナビゲーション情報等を表示する。 The display device 6 is composed of, for example, a liquid crystal display device and is provided so as to face the see-through portion 11 of the indicator plate 1 and displays measurement information, navigation information, and the like composed of travel distance data and outside air temperature data, for example.

このように構成された本実施例の指針式計器は、駆動装置５の駆動軸５１が計測量に応じて回転するよう設定されており、駆動軸５１の回転によって回転部材５２が回転すると、回転部材５２のギヤ列５３に噛み合うギヤ列２１を有する環状移動部材２が回転移動し、環状移動部材２に設けた指針３が、表示装置６が臨む透視部１１の外周で指標部１２を指示する。 The pointer type instrument of the present embodiment configured as described above is set so that the drive shaft 51 of the drive device 5 rotates according to the measurement amount, and the rotation of the rotation member 52 by the rotation of the drive shaft 51 causes the rotation. The annular moving member 2 having the gear train 21 that meshes with the gear train 53 of the member 52 rotates, and the pointer 3 provided on the annular moving member 2 indicates the indicator portion 12 on the outer periphery of the fluoroscopic portion 11 that the display device 6 faces. .

次に、本実施例の指針式計器の環状移動部材２の取付方法について説明する。 Next, a method for attaching the annular moving member 2 of the pointer-type meter according to this embodiment will be described.

本実施例の環状移動部材２は、すり鉢状の接触部２２のフレーム部材４側（下側）に第１のギヤ列２１を備えているので、環状移動部材２をフレーム部材４に取り付ける場合、第１のギヤ列２１が第１、第２の支持部材４３、４４の各回転体４３４、４４４を乗り越える必要がある。しかし、環状移動部材２をフレーム部材４の板面垂直方向からフレーム部材４に取り付ける場合は、第２の支持部材４３が環状移動部材２の内周方向には移動しないので、第１のギヤ列２１が第２の支持部材４４の回転体４４４を乗り越えることができないので取り付けることができない。 Since the annular moving member 2 of the present embodiment includes the first gear train 21 on the frame member 4 side (lower side) of the mortar-shaped contact portion 22, when attaching the annular moving member 2 to the frame member 4, It is necessary for the first gear train 21 to get over the rotating bodies 434 and 444 of the first and second support members 43 and 44. However, when the annular moving member 2 is attached to the frame member 4 from the direction perpendicular to the plate surface of the frame member 4, the second support member 43 does not move in the inner circumferential direction of the annular moving member 2. Since 21 cannot get over the rotating body 444 of the second support member 44, it cannot be attached.

そこで、以下の取付方法にて、環状移動部材２を取り付ける。まず第１に、第１のギヤ列２１が２つの第１の支持部材４３の回転体４３４を乗り越えて、接触部２２を２つの回転体４３４に接触させる。続いて第２に、環状移動部材２を図２中上方向に移動させる。この時、第１の支持部材４３の回転体４３４は環状移動部材２の接触部２２に接触しつつ、環状移動部材２の内周方向に移動する。環状移動部材２の移動は、２つの第２の支持部材４４の回転体４４４間の距離に対して、環状移動部材２のギヤ列２１の内周の距離が同等以上となるまで行う。続いて第３に、２つの第２の支持部材４４の回転体４４４間の距離に対して、環状移動部材２のギヤ列２１の内周の距離が同等以上となったところで、環状移動部材２のギヤ列２１が、第２の支持部材４４の回転体４４４を乗り越えさせるとともに、第１のギヤ列２１と回転部材５２の第２のギヤ列５３とを噛み合わせる。以上の取付方法によって、環状移動部材２をフレーム部材４に取り付けが完了する。 Therefore, the annular moving member 2 is attached by the following attachment method. First, the first gear train 21 gets over the rotating bodies 434 of the two first support members 43 to bring the contact portion 22 into contact with the two rotating bodies 434. Subsequently, secondly, the annular moving member 2 is moved upward in FIG. At this time, the rotating body 434 of the first support member 43 moves in the inner circumferential direction of the annular moving member 2 while being in contact with the contact portion 22 of the annular moving member 2. The movement of the annular moving member 2 is performed until the distance of the inner circumference of the gear train 21 of the annular moving member 2 becomes equal to or greater than the distance between the rotating bodies 444 of the two second support members 44. Subsequently, thirdly, when the distance of the inner circumference of the gear train 21 of the annular moving member 2 becomes equal to or greater than the distance between the rotating bodies 444 of the two second support members 44, the annular moving member 2 is used. The first gear train 21 and the second gear train 53 of the rotating member 52 mesh with each other while the second gear train 21 gets over the rotating body 444 of the second support member 44. The attachment of the annular moving member 2 to the frame member 4 is completed by the above attachment method.

次に、本実施例の指針式計器の動作について図５を用いて説明する。 Next, the operation of the pointer-type meter according to this embodiment will be described with reference to FIG.

図５の（ａ）は、環状移動部材２が反時計回り方向（図中の矢印方向）に回転する場合を示している。なお、回転体４３４、４４４は、左右で区別するために、それぞれ回転体４３４ａ、４３４ｂ、４４４ａ、４４４ｂとする。 FIG. 5A shows a case where the annular moving member 2 rotates in the counterclockwise direction (the arrow direction in the drawing). The rotating bodies 434 and 444 are referred to as rotating bodies 434a, 434b, 444a, and 444b, respectively, in order to distinguish them from left and right.

環状移動部材２が反時計回り方向に回転する場合、駆動装置５が環状移動部材２を反時計回りに移動させることとなる。この時、環状移動部材２は、回転部材５２と、第１の支持部材４３の回転体４３４ａ及び第２の支持部材４４の回転体４４４ｂの少なくとも３点によって支持される。 When the annular moving member 2 rotates counterclockwise, the drive device 5 moves the annular moving member 2 counterclockwise. At this time, the annular moving member 2 is supported by at least three points of the rotating member 52, the rotating body 434 a of the first supporting member 43, and the rotating body 444 b of the second supporting member 44.

この３点の内、回転部材５２の位置は不動であり、回転体４４４ｂの位置は環状移動部材２の外周方向へは変位するが内周方向へは変位しない。そして、回転体４３４ａは、第１の支持部材４３の付勢部材４３５によって、第２の支持部材４４の図示しない付勢部材に打ち勝って、環状移動部材２を外周方向に押しつけている。特に、第２の支持部材４４の回転体４４４ｂは、第２の支持部材４４の図示しない付勢部材によって、環状移動部材２を外周方向に押しつけているが、第１の支持部材４３の付勢部材４３５は、第２の支持部材４４の図示しない付勢部材よりも強い力で、環状移動部材２を外周方向に押しつけることによって、第２の支持部材４４の回転体４４４ｂの位置が内周方向へ変位できない位置とすることで、回転体４４４ｂの位置が環状移動部材２の回転中心が変位することのない正しい位置となる。そして、回転部材５２、回転体４４４ｂおよび回転体４３４ａの力の方向、特に、回転部材５２は不動であるので、回転体４４４ｂと回転体４３４ａとの力の方向が均衡し、駆動装置５によって回転されても、環状移動部材２の回転中心が変位することなく正しい位置に位置することができる。 Of these three points, the position of the rotating member 52 is stationary, and the position of the rotating body 444b is displaced in the outer peripheral direction of the annular moving member 2, but not in the inner peripheral direction. The rotating body 434a overcomes the biasing member ( not shown) of the second support member 44 by the biasing member 435 of the first support member 43 and presses the annular moving member 2 in the outer peripheral direction. In particular, the rotation body 444b of the second support member 44, by a biasing member (not shown) of the second support member 44, although pressed against the annular movable member 2 in the outer peripheral direction, biases the first support member 43 The member 435 presses the annular moving member 2 in the outer peripheral direction with a stronger force than the urging member ( not shown) of the second support member 44, so that the position of the rotating body 444b of the second support member 44 is in the inner peripheral direction. By making the position incapable of being displaced, the position of the rotating body 444b becomes a correct position in which the center of rotation of the annular moving member 2 is not displaced. The direction of the force of the rotating member 52, the rotating body 444b, and the rotating body 434a, in particular, the rotating member 52 is stationary, so that the direction of the force of the rotating body 444b and the rotating body 434a is balanced and rotated by the drive device 5. Even if this is done, the center of rotation of the annular moving member 2 can be positioned in the correct position without being displaced.

また、駆動装置５の回転部材５２の回転によって、図５の（ａ）中の環状移動部材２の左上側部分が外側に変形するが、第２の支持部材４４の回転体４４４ａが環状移動部材２の外周側に移動可能で、また、前記付勢部材によって、環状移動部材２の接触部２２に押しつけられているので、環状移動部材２と第２の支持部材４４の回転体４４４ａとの接触する圧力が低下することを防止し、接触する圧力の低下による回転体４４４ａの振動と、この振動に伴う振動音の発生を抑制することができる。 Further, the rotation of the rotating member 52 of the driving device 5 causes the upper left portion of the annular moving member 2 in FIG. 5A to be deformed outward, but the rotating body 444a of the second support member 44 is an annular moving member. 2 and can be moved to the outer peripheral side of the annular moving member 2 and is pressed against the contact portion 22 of the annular moving member 2 by the urging member, so that the annular moving member 2 and the rotating body 444a of the second support member 44 contact each other. The pressure of the rotating body 444a can be prevented from decreasing, and the vibration of the rotating body 444a due to the decrease of the contacting pressure and the generation of vibration noise accompanying this vibration can be suppressed.

図５の（ｂ）は、環状移動部材２が時計回り方向（図中の矢印方向）に回転する場合を示している。 FIG. 5B shows a case where the annular moving member 2 rotates in the clockwise direction (the arrow direction in the figure).

環状移動部材２が時計回り方向に回転する場合、環状移動部材２は、回転部材５２と、第１の支持部材４３の回転体４３４ｂ及び第２の支持部材４４の回転体４４４ａの少なくとも３点によって支持される。 When the annular moving member 2 rotates in the clockwise direction, the annular moving member 2 is constituted by at least three points of the rotating member 52, the rotating body 434b of the first support member 43, and the rotating body 444a of the second support member 44. Supported.

また、駆動装置５の回転部材５２の回転によって、図５の（ｂ）中の環状移動部材２の右上側部分が外側に変形するが、第２の支持部材４４の回転体４４４ｂが環状移動部材２の外周側に移動可能で、また、前記付勢部材によって、環状移動部材２の接触部２２に押しつけられているので、前記反時計回り方向の場合と同様に、環状移動部材２と第２の支持部材４４の回転体４４４ｂとの接触する圧力が低下することを防止し、接触する圧力の低下による回転体４４４ｂの振動と、この振動に伴う振動音の発生を抑制することができる。 Further, the rotation of the rotating member 52 of the driving device 5 causes the upper right side portion of the annular moving member 2 in FIG. 5B to be deformed outward, but the rotating body 444b of the second support member 44 is an annular moving member. 2 and can be moved to the outer peripheral side of the annular moving member 2 and is pressed against the contact portion 22 of the annular moving member 2 by the urging member. It is possible to prevent the contact pressure of the support member 44 with the rotating body 444b from being lowered, and to suppress the vibration of the rotating body 444b due to the decrease of the contacting pressure and the generation of vibration noise associated with this vibration.

なお、前記第１実施例では、回転部材５２と第１の支持部材４３及び第２の支持部材４４とは、環状移動部材２の内周に接していたが、前記実施例に限定されるものではなく、例えば、図６に示す本発明の第２実施例のように、環状移動部材１０２の外周に接するものであってもよい。 In the first embodiment, the rotating member 52, the first support member 43, and the second support member 44 are in contact with the inner periphery of the annular moving member 2, but are not limited to the above embodiment. Instead, for example, it may be in contact with the outer periphery of the annular moving member 102 as in the second embodiment of the present invention shown in FIG.

これから第２実施例について説明するが、第１実施例と同一及び相当個所には同一符号を付してその詳細な説明は省略する。 The second embodiment will be described below. The same reference numerals are used for the same and corresponding parts as in the first embodiment, and the detailed description thereof is omitted.

本実施例においては、環状移動部材１０２は外周に図示しない第１のギヤ列を備えている。また、第１の支持部材の回転体１４３４ａ、１４３４ｂは環状移動部材１０２の内周外周両方向に移動可能であり、第２の支持部材の回転体１４４４ａ、１４４４ｂは環状移動部材１０２の内周方向にのみ移動可能である。 In the present embodiment, the annular moving member 102 includes a first gear train (not shown) on the outer periphery. Further, the first support member rotators 1434a and 1434b are movable in both directions on the inner periphery and outer periphery of the annular moving member 102, and the second support member rotators 1444a and 1444b are disposed in the inner periphery direction of the annular movable member 102. Is only movable.

次に、本実施例の指針式計器の環状移動部材１０２の取付方法について説明する。まず第１に、環状移動部材１０２の前記第１のギヤ列が２つの第１の支持部材の回転体１４３４ａ、１４３４ｂを乗り越えて、環状移動部材１０２の接触部を２つの回転体１４３４ａ、１４３４ｂに接触させる。第２に、環状移動部材１０２を図６（ａ）中下方向に移動させる。この時、第１の支持部材の回転体１４３４ａ、１４３４ｂは環状移動部材２の接触部２２に接触しつつ、環状移動部材２の外周方向に移動する。環状移動部材１０２の移動は、２つの第２の支持部材の回転体１４４４ａ、１４４４ｂ間の距離に対して、環状移動部材１０２の前記ギヤ列の外周の距離が同等以下となるまで行う。続いて第３に、２つの第２の支持部材の回転体１４４４ａ、１４４４ｂ間の距離に対して、環状移動部材１０２の前記ギヤ列の外周の距離が同等以下となったところで、環状移動部材１０２の前記ギヤ列が、第２の支持部材の回転体１４４４ａ、１４４４ｂを乗り越えさせるとともに、環状移動部材１０２の前記第１のギヤ列と回転部材５２の第２のギヤ列５３とを噛み合わせる。以上の取付方法によって、環状移動部材１０２をフレーム部材４に取り付けが完了する。 Next, a method for attaching the annular moving member 102 of the pointer-type meter according to this embodiment will be described. First, the rotating body 1434a of the first of the first gear train is two support members of the annular movable member 102, rides over the 1434B, the contact portion of the annular movable member 102 two rotating bodies 1434a, the 1434B Make contact. Second, the annular moving member 102 is moved downward in FIG. At this time, the rotating bodies 1434a and 1434b of the first support member move in the outer circumferential direction of the annular moving member 2 while being in contact with the contact portion 22 of the annular moving member 2. The movement of the annular moving member 102 is performed until the distance of the outer periphery of the gear train of the annular moving member 102 becomes equal to or less than the distance between the rotating bodies 1444a and 1444b of the two second support members. Subsequently, thirdly, when the distance of the outer periphery of the gear train of the annular moving member 102 becomes equal to or less than the distance between the rotating bodies 1444a and 1444b of the two second supporting members, the annular moving member 102 The first gear train of the annular moving member 102 and the second gear train 53 of the rotary member 52 are engaged with each other, while the second gear train passes over the rotating bodies 1444a and 1444b of the second support member. With the above attachment method, the attachment of the annular moving member 102 to the frame member 4 is completed.

環状移動部材１０２が反時計回り方向に回転する場合、駆動装置５の回転部材５２が環状移動部材２を反時計回りに移動させることとなる。この時、環状移動部材１０２は、回転部材５２と、第１の支持部材の回転体１４３４ａ及び第２の支持部材の回転体１４４４ａの少なくとも３点によって支持される。 When the annular moving member 102 rotates in the counterclockwise direction, the rotating member 52 of the driving device 5 moves the annular moving member 2 in the counterclockwise direction. At this time, the annular moving member 102 is supported by at least three points of the rotating member 52, the first supporting member rotating body 1434a, and the second supporting member rotating body 1444a.

この３点の内、回転部材５２の位置は不動であり、回転体１４４４ａの位置は環状移動部材２の内周方向へは変位するが外周方向へは変位しない。そして、回転体１４３４ａは、第１の支持部材４３の付勢部材４３５によって、第２の支持部材４４の図示しない付勢部材に打ち勝って、環状移動部材２を内周方向に押しつけている。特に、第２の支持部材４４の回転体１４４４ａは、第２の支持部材４４の図示しない付勢部材によって、環状移動部材２を内周方向に押しつけているが、第１の支持部材４３の付勢部材４３５は、第２の支持部材４４の図示しない付勢部材よりも強い力で、環状移動部材２を内周方向に押しつけることによって、第２の支持部材４４の回転体１４４４ａの位置が外周方向へ変位できない位置とすることで、回転体１４４４ａの位置が環状移動部材２の回転中心が変位することのない正しい位置となる。そして、回転部材５２、回転体１４４４ａおよび回転体１４３４ａの力の方向、特に、回転部材５２は不動であるので、回転体１４４４ａと回転体１４３４ａとの力の方向が均衡し、駆動装置５によって回転されても、環状移動部材２の回転中心が変位することなく正しい位置に位置することができる。 Of these three points, the position of the rotating member 52 is stationary, and the position of the rotating body 1444a is displaced in the inner circumferential direction of the annular moving member 2 but not in the outer circumferential direction. The rotating body 1434a overcomes the biasing member ( not shown) of the second support member 44 by the biasing member 435 of the first support member 43, and presses the annular moving member 2 in the inner circumferential direction. In particular, rotation member 1444a of the second support member 44, by a biasing member (not shown) of the second support member 44, although pressed against the annular movable member 2 in the inner circumferential direction, with the first support member 43 The biasing member 435 presses the annular moving member 2 in the inner circumferential direction with a stronger force than the biasing member ( not shown) of the second support member 44, so that the position of the rotating body 1444 a of the second support member 44 is changed to the outer circumference. By setting the position so that it cannot be displaced in the direction, the position of the rotating body 1444a becomes the correct position where the center of rotation of the annular moving member 2 is not displaced. The direction of the force of the rotating member 52, the rotating body 1444a, and the rotating body 1434a, in particular, the rotating member 52 is stationary, so that the direction of the force between the rotating body 1444a and the rotating body 1434a is balanced and rotated by the drive device 5. Even if this is done, the center of rotation of the annular moving member 2 can be positioned in the correct position without being displaced.

また、駆動装置５の回転部材５２の回転によって、図６の（ａ）中の環状移動部材１０２の右上側部分が内側に変形するが、第２の支持部材の回転体１４４４ｂが環状移動部材２の内周側に移動可能で、また、前記付勢部材によって、環状移動部材１０２の接触部を押しつけているので、環状移動部材１０２と第２の支持部材の回転体１４４４ｂとの接触する圧力が低下することを防止し、接触する圧力の低下による回転体１４４４ｂの振動と、この振動に伴う振動音の発生を抑制することができる。 Further, the upper right side portion of the annular moving member 102 in FIG. 6A is deformed inward by the rotation of the rotating member 52 of the driving device 5 , but the rotating body 1444 b of the second support member is the annular moving member 2. Further, the contact portion of the annular moving member 102 is pressed by the biasing member, so that the pressure at which the annular moving member 102 and the rotating body 1444b of the second support member come into contact with each other is increased. It is possible to prevent the decrease, and to suppress the vibration of the rotating body 1444b due to the decrease in the contact pressure and the generation of the vibration sound accompanying this vibration.

図６の（ｂ）は、環状移動部材１０２が時計回り方向（図中の矢印方向）に回転する場合を示している。 FIG. 6B shows a case where the annular moving member 102 rotates in the clockwise direction (the arrow direction in the figure).

環状移動部材１０２が時計回り方向に回転する場合、環状移動部材１０２は、回転部材５２と、第１の支持部材の回転体１４３４ｂ及び第２の支持部材の回転体１４４４ｂの少なくとも３点によって支持される。 When the annular moving member 102 rotates in the clockwise direction, the annular moving member 102 is supported by at least three points of the rotating member 52, the first supporting member rotating body 1434b, and the second supporting member rotating body 1444b. The

また、回転部材５２の回転によって、図６の（ｂ）中の環状移動部材２の左上側部分が内側に変形するが、第２の支持部材の回転体１４４４ａが環状移動部材１０２の内周側に移動可能で、また、前記付勢部材によって、環状移動部材１０２の接触部２２に押しつけられているので、前記反時計回り方向の場合と同様に、環状移動部材１０２と第２の支持部材の回転体１４４４ａとの接触する圧力が低下することを防止し、接触する圧力の低下による回転体１４４４ａの振動と、この振動に伴う振動音の発生を抑制することができる。 6B, the upper left portion of the annular moving member 2 in FIG. 6B is deformed inward, but the rotating member 1444a of the second support member is the inner peripheral side of the annular moving member 102. Since the biasing member is pressed against the contact portion 22 of the annular moving member 102, the annular moving member 102 and the second supporting member are It is possible to prevent a decrease in the pressure in contact with the rotating body 1444a, and to suppress the vibration of the rotating body 1444a due to the decrease in the contacting pressure and the generation of vibration sound associated with the vibration.

なお、前記各実施例では、第１の支持部材４３を隣り合うように２つ設けていたが、前記各実施例に限定されるものではなく、第１の支持部材４３を１つだけ設け、回転部材５２と第１の支持部材４３との間に第２の支持部材４４を設けるようにしてもよい。 In each of the above embodiments, two first support members 43 are provided so as to be adjacent to each other. However, the present invention is not limited to each of the above embodiments, and only one first support member 43 is provided. The second support member 44 may be provided between the rotating member 52 and the first support member 43.

例えば、図７に示すように、環状移動部材２の内周に接する場合を本発明の第３実施例として説明する。なお、前記各実施例と同一及び相当個所には同一符号を付してその詳細な説明は省略する。 For example, as shown in FIG. 7, described with the third embodiment of the present invention when in contact with the inner circumference of the annular movable member 2. In addition, the same code | symbol is attached | subjected to the same and equivalent part as the said each Example, and the detailed description is abbreviate | omitted.

環状移動部材２が反時計回り方向に回転する場合、駆動装置５が環状移動部材２を反時計回りに移動させることとなる。この時、環状移動部材２は、回転部材５２と、第１の支持部材４３の回転体４３４及び第２の支持部材４４の回転体４４４ｂの少なくとも３点によって支持される。 When the annular moving member 2 rotates counterclockwise, the drive device 5 moves the annular moving member 2 counterclockwise. At this time, the annular moving member 2 is supported by at least three points of the rotating member 52, the rotating body 434 of the first supporting member 43, and the rotating body 444 b of the second supporting member 44.

この３点の内、回転部材５２の位置は不動であり、回転体４４４ｂの位置は環状移動部材２の外周方向へは変位するが内周方向へは変位しない。そして、回転体４３４は、第１の支持部材４３の付勢部材４３５によって、第２の支持部材４４の図示しない付勢部材に打ち勝って、環状移動部材２を外周方向に押しつけている。特に、第２の支持部材４４の回転体４４４ｂは、第２の支持部材４４の図示しない付勢部材によって、環状移動部材２を外周方向に押しつけているが、第１の支持部材４３の付勢部材４３５は、第２の支持部材４４の図示しない付勢部材よりも強い力で、環状移動部材２を外周方向に押しつけることによって、第２の支持部材４４の回転体４４４ｂの位置が内周方向へ変位できない位置とすることで、回転体４４４ｂの位置が環状移動部材２の回転中心が変位することのない正しい位置となる。そして、回転部材５２、回転体４４４ｂおよび回転体４３４の力の方向、特に、回転部材５２は不動であるので、回転体４４４ｂと回転体４３４との力の方向が均衡し、駆動装置５によって回転されても、環状移動部材２の回転中心が変位することなく正しい位置に位置することができる。 Of these three points, the position of the rotating member 52 is stationary, and the position of the rotating body 444b is displaced in the outer peripheral direction of the annular moving member 2, but not in the inner peripheral direction. The rotating body 434 overcomes the biasing member ( not shown) of the second support member 44 by the biasing member 435 of the first support member 43 and presses the annular moving member 2 in the outer peripheral direction. In particular, the rotation body 444b of the second support member 44, by a biasing member (not shown) of the second support member 44, although pressed against the annular movable member 2 in the outer peripheral direction, biases the first support member 43 The member 435 presses the annular moving member 2 in the outer peripheral direction with a stronger force than the urging member ( not shown) of the second support member 44, so that the position of the rotating body 444b of the second support member 44 is in the inner peripheral direction. By making the position incapable of being displaced, the position of the rotating body 444b becomes a correct position in which the center of rotation of the annular moving member 2 is not displaced. The direction of the force of the rotating member 52, the rotating body 444b, and the rotating body 434, in particular, the rotating member 52 is stationary, so that the direction of the force of the rotating body 444b and the rotating body 434 is balanced and rotated by the drive device 5. Even if this is done, the center of rotation of the annular moving member 2 can be positioned in the correct position without being displaced.

また、駆動装置５の回転部材５２の回転によって、図７の（ａ）中の環状移動部材２の左側部分が外側に変形するが、第２の支持部材４４の回転体４４４ａが環状移動部材２の外周側に移動可能で、また、前記付勢部材によって、環状移動部材２の接触部２２に押しつけられているので、環状移動部材２と第２の支持部材４４の回転体４４４ａとの接触する圧力が低下することを防止し、接触する圧力の低下による回転体４４４ａの振動と、この振動に伴う振動音の発生を抑制することができる。 Further, the rotation of the rotating member 52 of the driving device 5 causes the left side portion of the annular moving member 2 in FIG. Since the pressing member is pressed against the contact portion 22 of the annular moving member 2 by the biasing member, the annular moving member 2 comes into contact with the rotating body 444a of the second support member 44. It is possible to prevent the pressure from being lowered, and to suppress the vibration of the rotating body 444a due to the reduction in the contacting pressure and the generation of the vibration sound accompanying this vibration.

図７の（ｂ）は、環状移動部材２が時計回り方向（図中の矢印方向）に回転する場合を示している。 FIG. 7B shows a case where the annular moving member 2 rotates in the clockwise direction (the arrow direction in the drawing).

環状移動部材２が時計回り方向に回転する場合、環状移動部材２は、回転部材５２と、第１の支持部材４３の回転体４３４及び第２の支持部材４４の回転体４４４ａの少なくとも３点によって支持される。 When the annular moving member 2 rotates in the clockwise direction, the annular moving member 2 is constituted by at least three points of the rotating member 52, the rotating body 434 of the first support member 43, and the rotating body 444a of the second support member 44. Supported.

また、駆動装置５の回転部材５２の回転によって、図７の（ｂ）中の環状移動部材２の右側部分が外側に変形するが、第２の支持部材４４の回転体４４４ｂが環状移動部材２の外周側に移動可能で、また、前記付勢部材によって、環状移動部材２の接触部２２に押しつけられているので、前記反時計回り方向の場合と同様に、環状移動部材２と第２の支持部材４４の回転体４４４ｂとの接触する圧力が低下することを防止し、接触する圧力の低下による回転体４４４ｂの振動と、この振動に伴う振動音の発生を抑制することができる Further, the right side portion of the annular moving member 2 in FIG. 7B is deformed outward by the rotation of the rotating member 52 of the driving device 5, but the rotating body 444 b of the second support member 44 is the annular moving member 2. Since the urging member is pressed against the contact portion 22 of the annular moving member 2, the annular moving member 2 and the second moving member 2 can be moved in the same manner as in the counterclockwise direction. The pressure at which the support member 44 comes into contact with the rotating body 444b can be prevented from decreasing, and the vibration of the rotating body 444b due to the decrease in the contacting pressure and the generation of vibration noise associated with this vibration can be suppressed.

また、前記第３実施例では、回転部材５２と第１の支持部材４３及び第２の支持部材４４とは、環状移動部材２の内周に接していたが、図８に示す本発明の第４実施例のように、環状移動部材１０２の外周に接するものであってもよい。 In the third embodiment, the rotating member 52, the first support member 43, and the second support member 44 are in contact with the inner periphery of the annular moving member 2, but the present invention shown in FIG. It may be in contact with the outer periphery of the annular moving member 102 as in the fourth embodiment.

本実施例においても、前記各実施例と同一及び相当個所には同一符号を付してその詳細な説明は省略する。 Also in the present embodiment, the same reference numerals are assigned to the same and corresponding portions as those in the above-described embodiments, and the detailed description thereof is omitted.

第１の支持部材の回転体１４３４は環状移動部材１０２の内周外周両方向に移動可能であり、第２の支持部材の回転体１４４４ａ、１４４４ｂは環状移動部材１０２の内周方向にのみ移動可能である。 The first support member rotator 1434 is movable in both directions on the inner periphery and outer periphery of the annular moving member 102, and the second support member rotators 1444 a and 1444 b are movable only in the inner periphery direction of the annular moving member 102. is there.

環状移動部材１０２が反時計回り方向に回転する場合、駆動装置５の回転部材５２が環状移動部材２を反時計回りに移動させることとなる。この時、環状移動部材１０２は、回転部材５２と、第１の支持部材の回転体１４３４及び第２の支持部材の回転体１４４４ａの少なくとも３点によって支持される。 When the annular moving member 102 rotates in the counterclockwise direction, the rotating member 52 of the driving device 5 moves the annular moving member 2 in the counterclockwise direction. At this time, the annular moving member 102 is supported by at least three points of the rotating member 52, the rotating body 1434 of the first supporting member, and the rotating body 1444a of the second supporting member.

この３点の内、回転部材５２の位置は不動であり、回転体１４４４ａの位置は環状移動部材２の内周方向へは変位するが外周方向へは変位しない。そして、回転体１４３４は、第１の支持部材４３の付勢部材４３５によって、第２の支持部材４４の図示しない付勢部材に打ち勝って、環状移動部材２を内周方向に押しつけている。特に、第２の支持部材４４の回転体１４４４ａは、第２の支持部材４４の図示しない付勢部材によって、環状移動部材２を内周方向に押しつけているが、第１の支持部材４３の付勢部材４３５は、第２の支持部材４４の図示しない付勢部材よりも強い力で、環状移動部材２を内周方向に押しつけることによって、第２の支持部材４４の回転体１４４４ａの位置が外周方向へ変位できない位置とすることで、回転体１４４４ａの位置が環状移動部材２の回転中心が変位することのない正しい位置となる。そして、回転部材５２、回転体１４４４ａおよび回転体１４３４の力の方向、特に、回転部材５２は不動であるので、回転体１４４４ａと回転体１４３４との力の方向が均衡し、駆動装置５によって回転されても、環状移動部材２の回転中心が変位することなく正しい位置に位置することができる。 Of these three points, the position of the rotating member 52 is stationary, and the position of the rotating body 1444a is displaced in the inner circumferential direction of the annular moving member 2 but not in the outer circumferential direction. The rotating body 1434 overcomes the biasing member ( not shown) of the second support member 44 by the biasing member 435 of the first support member 43 and presses the annular moving member 2 in the inner circumferential direction. In particular, rotation member 1444a of the second support member 44, by a biasing member (not shown) of the second support member 44, although pressed against the annular movable member 2 in the inner circumferential direction, with the first support member 43 The biasing member 435 presses the annular moving member 2 in the inner circumferential direction with a stronger force than the biasing member ( not shown) of the second support member 44, so that the position of the rotating body 1444 a of the second support member 44 is changed to the outer circumference. By setting the position so that it cannot be displaced in the direction, the position of the rotating body 1444a becomes the correct position where the center of rotation of the annular moving member 2 is not displaced. The direction of the force of the rotating member 52, the rotating body 1444a, and the rotating body 1434, in particular, the rotating member 52 is stationary, so that the direction of the force of the rotating body 1444a and the rotating body 1434 is balanced and rotated by the driving device 5. Even if this is done, the center of rotation of the annular moving member 2 can be positioned in the correct position without being displaced.

また、駆動装置５の回転部材５２の回転によって、図８の（ａ）中の環状移動部材１０２の右側部分が内側に変形するが、第２の支持部材の回転体１４４４ｂが環状移動部材２の内周側に移動可能で、また、前記付勢部材によって、環状移動部材１０２の接触部を押しつけているので、環状移動部材１０２と第２の支持部材の回転体１４４４ｂとの接触する圧力が低下することを防止し、接触する圧力の低下による回転体１４４４ｂの振動と、この振動に伴う振動音の発生を抑制することができる。 Further, the right side portion of the annular moving member 102 in FIG. 8A is deformed inward by the rotation of the rotating member 52 of the driving device 5 , but the rotating body 1444 b of the second support member is The contact portion of the annular moving member 102 is pressed by the urging member, and the pressure at which the annular moving member 102 and the rotating body 1444b of the second support member contact decreases. It is possible to prevent the vibration of the rotating body 1444b due to a decrease in the contact pressure and the generation of vibration noise associated with this vibration.

図８の（ｂ）は、環状移動部材１０２が時計回り方向（図中の矢印方向）に回転する場合を示している。 FIG. 8B shows a case where the annular moving member 102 rotates in the clockwise direction (the arrow direction in the drawing).

環状移動部材１０２が時計回り方向に回転する場合、環状移動部材１０２は、回転部材５２と、第１の支持部材の回転体１４３４及び第２の支持部材の回転体１４４４ｂの少なくとも３点によって支持される。 When the annular moving member 102 rotates clockwise, the annular moving member 102 is supported by at least three points of the rotating member 52, the first supporting member rotating body 1434, and the second supporting member rotating body 1444b. The

また、回転部材５２の回転によって、図８の（ｂ）中の環状移動部材２の左側部分が内側に変形するが、第２の支持部材の回転体１４４４ａが環状移動部材１０２の内周側に移動可能で、また、前記付勢部材によって、環状移動部材１０２の接触部２２を押しつけられているので、前記反時計回り方向の場合と同様に、環状移動部材１０２と第２の支持部材の回転体１４４４ａとの接触する圧力が低下することを防止し、接触する圧力の低下による回転体１４４４ａの振動と、この振動に伴う振動音の発生を抑制することができる。 Further, the rotation of the rotating member 52 causes the left side portion of the annular moving member 2 in FIG. 8B to be deformed inward, but the rotating body 1444a of the second support member is located on the inner peripheral side of the annular moving member 102. Since the movable member is movable and the contact portion 22 of the annular moving member 102 is pressed by the biasing member, the rotation of the annular moving member 102 and the second support member is the same as in the counterclockwise direction. It is possible to prevent the contact pressure with the body 1444a from decreasing, and to suppress the vibration of the rotating body 1444a due to the decrease in the contact pressure and the generation of vibration sound associated with this vibration.
