うになつている。(Prior Art) Conventionally, for example, a speed display device for a continuously variable transmission device,
As shown in FIGS. 3 and 4, a pointer 5' fixed to a nut 3' screwed onto a speed change screw 2' disposed inside a transmission case 1' filled with lubricating oil is connected to a speed change screw 2'. The position of the pointer 5' can be seen through a transparent cover 10' made of synthetic resin, etc., which is fixed to the case 1', and the position of the pointer 5' can be seen from the scale carved on the transparent cover 10'. The gear ratio is detected by comparison.

完全に防止することはできなかつた。(Problem to be Solved by the Invention) In the conventional speed display device of a continuously variable transmission, oil in the case 1' may leak to the upper surface of the pointer 5' or the transparent cover 10'.
If the inner circumferential surface of the nut 3' becomes dirty, the transparency becomes low and the position of the pointer 5' cannot be detected accurately, so a gasket 12 for an oil seal is provided between the pointer 5' and the nut 3'. Although the lubricating oil filled in the case 1' is prevented from entering the pointer 5' side, it is essential that the nut 3' slides along the speed change screw 2'. It is difficult to reliably seal the sliding surfaces, and it has not been possible to completely prevent lubricating oil from adhering to the pointer 5' and the transparent cover 10'.

確に検知することを可能にしたものである。(Means for Solving the Problems) This invention provides a pointer display device installed in a place where the speed pointer of a transmission or an oil level gauge is immersed in oil or where oil is splashed and attached.
An elastic body such as a coil spring is interposed between the movable pointer holder and the pointer, and the pointer is always in sliding contact with the transparent cover made of synthetic resin, etc., so that the pointer can be placed on the inner surface of the transparent cover. By pressing and sliding, oil and other deposits adhering to the inner surface of the transparent cover when the pointer slides are scraped off, and the transparency of the transparent cover is always maintained at a high level, so that the position of the pointer can be accurately detected. This is what made it possible.
（実施例）
以下、この考案を無段変速機の速度表示装置に
実施した実施例に沿い説明する。(Example) Hereinafter, a description will be given of an example in which this invention is implemented in a speed display device for a continuously variable transmission.
第１図及び第２図を参照して、
１はケース、２は該ケース１内に配設した変速
ネジで、該ネジ２には自転を拘束されたナツト３
が螺合されている。 Referring to FIGS. 1 and 2, 1 is a case, 2 is a speed change screw disposed inside the case 1, and the screw 2 has a nut 3 whose rotation is restrained.
are screwed together.
そして、該ナツト３には図示しない変速デイス
クが連設されており、変速ナツト３の移動により
変速デイスクとコーンとの相対接触半径を変える
ことにより無段階に変速可能となつている。 A speed change disk (not shown) is connected to the nut 3, and by changing the relative contact radius between the speed change disk and the cone by moving the speed change nut 3, the speed can be changed steplessly.
４は前記ナツト３にケース１の内面（後述する
透明カバー側）に向つて突出するように固定され
た指針ホルダーで、該ホルダー４には指針５が摺
動可能に嵌入されると共に、前記ホルダー４と指
針５との間にはコイルバネ６等の弾性体が介装さ
れている。 Reference numeral 4 denotes a pointer holder fixed to the nut 3 so as to protrude toward the inner surface of the case 1 (transparent cover side to be described later).A pointer 5 is slidably fitted into the holder 4, and the pointer 5 4 and the pointer 5, an elastic body such as a coil spring 6 is interposed.
従つて、指針５は常にケース１の内面側に突出
可弾性力が付勢されている。 Therefore, the pointer 5 is always biased toward the inner surface of the case 1 by an elastic force.
７はアルミニウム製等の固定枠で、前記ケース
１にボルト８によつて固定されると共に、前記ナ
ツト３の移動方向に沿つて細長い切欠き穴９が設
けられている。 Reference numeral 7 denotes a fixing frame made of aluminum or the like, which is fixed to the case 1 with bolts 8 and is provided with an elongated notch 9 along the moving direction of the nut 3.
１０は合成樹脂製等の透明カバーで、前記ケー
ス１と固定枠７との間に挾持されており、かつケ
ース１と固定枠７とに挾まれた周面（シール面）
にはケース１内に充填された潤滑油の漏洩を防止
するためのパツキン１１が設けられている。 Reference numeral 10 denotes a transparent cover made of synthetic resin or the like, which is sandwiched between the case 1 and the fixed frame 7, and has a peripheral surface (sealing surface) sandwiched between the case 1 and the fixed frame 7.
A gasket 11 is provided to prevent the lubricating oil filled in the case 1 from leaking.
従つて、変速ネジ２を回転することにより前記
指針５は透明カバー１０の内面に押圧されながら
固定枠７に設けた切欠き穴９に沿つて摺動するの
で、透明カバー１０の内面は摺動する指針５によ
つて磨かれるので、透明カバー１０に直接目盛を
刻むか、或いは目盛シールを貼着しておくことに
より、指針５の位置を常に正確に検知することが
できる。 Therefore, by rotating the speed change screw 2, the pointer 5 slides along the notch hole 9 provided in the fixed frame 7 while being pressed against the inner surface of the transparent cover 10, so that the inner surface of the transparent cover 10 does not slide. The position of the pointer 5 can always be accurately detected by carving a scale directly on the transparent cover 10 or by pasting a scale sticker on the transparent cover 10.
なお、本実施例は左右方向に摺動するナツト３
に指針５を装着した速度表示装置について例示し
たが、オイルレベルゲージ等、油面の高さに応じ
て昇降するフロートをガイドバー等で一定方向に
上下するようにガイドし、該フロートに前記実施
例に示した如き指針を装着して油面レベルを検知
するオイルレベルゲージ等にも応用できることは
いうまでもない。 Note that this embodiment uses a nut 3 that slides in the left and right direction.
Although a speed display device equipped with a pointer 5 is illustrated in FIG. Needless to say, the present invention can also be applied to an oil level gauge, etc., which detects the oil level by attaching a pointer as shown in the example.
