The pointer 3 and the indicator 11 are light transmissive and emit light upon receiving light from a light source (not shown).

ベース部材４は、金属と合成樹脂との複合体からなり、図示しないスペーサ等を通じて回路基板７上に設置されている。このベース部材４は、金属製円板からなる母材部（金属部）４１と、この母材部４２の一部（複数箇所）を部分的に被覆するようにアウトサート成形（母材部４１となる金属材を金型内にセットした後、金属材の必要箇所に樹脂を射出成形し、合成樹脂部を形成する）により形成された合成樹脂部４２とを備える。 The base member 4 is made of a composite of metal and synthetic resin, and is installed on the circuit board 7 through a spacer (not shown). The base member 4 includes a base material portion (metal portion) 41 made of a metal disk and an outsert molding (base material portion 41) so as to partially cover a part (a plurality of locations) of the base material portion 42. And a synthetic resin portion 42 formed by injection molding a resin at a necessary portion of the metal material to form a synthetic resin portion.

母材部４１は、図３，図４にも示すように、指標板１の透視部１１及び表示装置６に対応する貫通部４３と、移動部材２と駆動部材５との連結を可能にするために駆動装置５を露出させる露出部４４とを有すると共に、外周部が略９０度背後側に折り曲げられることにより補強部４５が形成されている。なお孔状の貫通部４３及び露出部４４と折曲部状の補強部４５は、プレス成形により形成されている。 As shown in FIGS. 3 and 4, the base material portion 41 enables connection between the see-through portion 11 of the indicator plate 1 and the penetration portion 43 corresponding to the display device 6, the moving member 2, and the driving member 5. Therefore, the reinforcing portion 45 is formed by having the exposed portion 44 exposing the driving device 5 and bending the outer peripheral portion approximately 90 degrees to the rear side. The hole-shaped through portion 43 and the exposed portion 44 and the bent portion-shaped reinforcing portion 45 are formed by press molding.

合成樹脂部４２は、移動部材２を接触支持する支持箇所及び当該支持箇所を支承する支承箇所となるもので、移動部材２と直接接触し、これを支持する支持部４２ａを形成すると共に、移動部材２と直接接触してこれを支持するための支持部材８ａ，８ｂを支承する支承部４２ｂと、支持部４２ａや支承部４２ｂを繋ぐ連結部４２ｃ（図４参照）と形成している。 The synthetic resin portion 42 is a support location for supporting and supporting the moving member 2 and a support location for supporting the support location. The synthetic resin portion 42 is in direct contact with the moving member 2 and forms a support portion 42a for supporting the moving member 2 and moves. A support part 42b for supporting the support members 8a and 8b for directly contacting and supporting the member 2 and a connecting part 42c (see FIG. 4) for connecting the support part 42a and the support part 42b are formed.

すなわち支持部４２ａは、図５，図７に詳しく示すように、移動部材２の底面に点接触するスラスト方向支持部を構成する。 That is, the support portion 42a constitutes a thrust direction support portion that makes point contact with the bottom surface of the moving member 2, as shown in detail in FIGS.

また支承部４２ｂは、図５に詳しく示すように、柔軟性合成ゴムまたは合成樹脂からなり、移動部材２の接触部２２に接触して移動部材２のラジアル方向支持部を構成するガイドローラ８１と、このガイドローラ８１を回転可能に軸支する例えば金属製の軸部８２とで構成される支持部材８ａのうち、軸部８２を直接固定支持し、ガイドローラ８１を間接的に支持することにより、支持部材８ａを支承する。 Further, as shown in detail in FIG. 5, the support portion 42 b is made of a flexible synthetic rubber or synthetic resin, and contacts with the contact portion 22 of the moving member 2 to form a radial direction support portion of the moving member 2.

また連結部４２ｃ（図４参照）は、アウトサート成形により支持部４２ａや支承部４２ｂを形成する際に合成樹脂の通り道となる（なった）箇所であり、このように連結部４２ｃを設定することにより、金型に形成するゲートの数を削減でき、金型自体の構成を簡素化できると共に、成形作業の容易化も達成できるものである。 Further, the connecting portion 42c (see FIG. 4) is a place that becomes a passage for the synthetic resin when the support portion 42a and the support portion 42b are formed by outsert molding. Thus, the connecting portion 42c is set. As a result, the number of gates formed in the mold can be reduced, the structure of the mold itself can be simplified, and the molding operation can be facilitated.

駆動装置５は、例えばステッピングモータからなり、図７に詳しく示すように、回路基板７上に接続固定されている。駆動装置５の駆動軸５１は、前方に延びており、回転部材５２と、規制手段５３とが設けられている。 The drive device 5 is formed of, for example, a stepping motor, and is connected and fixed on the circuit board 7 as shown in detail in FIG.

The moving member 2 having the gear train 21 meshing with the gear train 54 of the member 52 rotates, and the pointer 3 provided on the moving member 2 indicates the indicator portion 12 on the outer periphery of the fluoroscopic portion 11 facing the display device 6.

ここでベース部材４に注目すると、ベース部材４は、金属製板材からなる母材部４１と、この母材部４１を部分的に被覆する合成樹脂部４２とを有する異質材料の複合体からなり、母材部４１を金属とすることで部材自体の強度、剛性の維持または向上を図りながら薄型化を達成し、しかも母材部４１に合成樹脂部４２を部分形成することで移動部材２の支持性または支持部材８ａ，８ｂの支承性を確保または向上させている。 Here, paying attention to the base member 4, the base member 4 is composed of a composite of heterogeneous materials having a base material part 41 made of a metal plate material and a synthetic resin part 42 partially covering the base material part 41. The base material portion 41 is made of metal to achieve a reduction in thickness while maintaining or improving the strength and rigidity of the member itself, and the synthetic resin portion 42 is partially formed on the base material portion 41 so that the moving member 2 Supportability or supportability of the support members 8a and 8b is ensured or improved.
