本発明は、速度計等のたわみ軸接続装匝におけるオイル
押え構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil holding structure in a flexible shaft connection fitting for a speedometer or the like.
自動車等の速度計たわみ軸は速度計を駆動するために速

７６号に記載されたものがある。The speedometer deflection shaft of automobiles, etc. is used to rotationally connect the speedometer to the transmission to drive the speedometer, or is used as a device to connect the deflection shaft to the transmission. 213
There is one described in No. 76.
このたわみ［１ｌｌＩｌｌ接続に直は、第１因に示すよ

インナーワイヤ２ｂに連結されている。The part 1a includes an outer wire 2a of the flexure shaft 2 with reference symbols 3a, 3b.
As shown in , the part 1c is held rotatably by being prevented from coming out by narrowing the rolling motion, and the pinion gear 4 that meshes with the drive wheel on the transmission side is held at the end of the part 1c by being prevented from coming out by a clip 5. , the central protruding portion 4a of this pinion gear 4 is connected to the inner wire 2b of the flexible shaft 2 through the opening 1d of the component 1c.

がある。Since such a connection case l is exposed to the lubricating oil of the transmission, it adheres to the inner wire 2b of the sliding shaft 2, and is then moved along the inner wire due to the high speed rotation of this inner wire. This may cause the polypropylene forming the outer coating layer of the outer wire to swell, and the lubricating oil may flow eastwards and into the gap between the outer wire 2a and the inner wire +b.
This has the disadvantage of penetrating the inner workings of the meter and adversely affecting its operation.

止めをおこなっている。Therefore, as similarly shown in FIG. 1, an oil presser 6 made of, for example, nylon with excellent oil resistance is provided, and this oil presser 6 is a portion that surrounds and connects the end of the outer wire 2a of the flexible shaft 2. 6a and a portion 6b surrounding the outer wire side portion of the inner wire 2b further extending from the outer wire. The portion 6a is fitted into the enlarged portion le of the connecting portion 1a, and the portion 6b has internal teeth 6c and is fitted into the inner wire 2bK of the flexible shaft 2 to seal this portion. Further, a stopper member 8 interposed together with a gasket 7 engages with a stepped portion 6d formed between portions 6a and 6b of the oil presser 6 to prevent the oil presser 6 from coming off.

悪影響を及はすなどの不都合は除去される。By disposing such an oil retainer 6 in the connecting member 1, the gap between the outer wire 2a and the inner wire 2b having a deflection of 1lli12 is sealed, so that even if the sliding surface oil of the transmission is The inner wire 2b penetrates into the connecting component IC through the hole 1d.
Even if it flows along the inner wire due to the high speed rotation of this inner wire, it is blocked by the oil retainer 6 and does not enter the gap between the outer wire and the inner wire of the deflection shaft. Inconveniences such as swelling of the outer coating layer (polypropylene) of the wire or lubricating oil of the transmission penetrating into the inner parts of the speedometer etc. and adversely affecting its operation are eliminated.

かかるなどの問題もある。However, even if such an oil presser 6 is provided,
Since the inner wire 2b of the flexible shaft 2 rotates too fast, it is difficult to completely block out the feed oil, and there is a problem in that it is not possible to completely prevent oil from entering the gap between the outer wire 2a and the inner wire 2b. be. Further, according to this oil presser 6, it is necessary to machine internal teeth 6c on the portion 6b, but since this tooth processing is performed after the oil presser itself is molded, it takes time and effort to assemble the oil presser. There are also other problems.
本発明は、このような問題を解消するためになされたも

る。According to the present invention, a first oil presser having a spiral oil push-back outer periphery in a direction opposite to the remaining direction of the inner wire of the deflection shaft is inserted and fixed to the inner wire, and the first oil presser is deflected. Insert it inside the cylindrical extension of the second oil holder, which is hidden between the outer wire of the shaft and the connection case that rotatably holds this outer wire, and remove the TFIK sliding oil inside this second oil holder. Even if the lubricant gets in, the first oil retainer rotates at a high speed together with the inner wire of the deflection shaft, and the spiral groove on the outer periphery pushes the intruding oil back in the direction in which it came in, thereby separating the outer wire and the inner wire. This completely prevents oil from entering the gap between the

Insert the first oil holder 11 that has a spiral oil push-back outer circumference StO in the direction opposite to the direction in which the wire is warped, and insert the pinion gear 4 (see Fig. 1) at the end of the first oil holder 11. Inserted metal collar 12
The first oil presser 11 is fixed to the inner wire 2b by compressing the outer wire 2a of the flexible shaft 2 and the connecting case 1 that rotatably holds the outer wire.

る。Therefore, if the first and second oils are like this,
and 13, if = a nu enters through the hole 1d of the component 1c of the connection case 1 and attaches to the inner wire 2b of the deflection shaft 2, the rotation of this inner wire at speed h causes a Even if it flows and enters between the first and second oil presses 11 and 13 through the gap C between the collar 12 and the second oil presser 13 (see Figure 3), it will flow together with the inner wire 2b. The first rotating at high speed
The outer circumferential spiral groove 10 of the oil presser 11 pushes the invading anti-lubricating oil back in the direction of intrusion, and removes the oil from the outer wire 2a.
This completely prevents oil from entering the gap between the wire and the inner wire 2b. Further, both the oil pressers 11 and 13 can be made of oil-resistant nylon, and in this case, both of these oil pressers are the same as the oil presser 6 shown in FIG.
Since the structure does not include the inner peripheral mill 6c (see FIG. 1), there is no need for post-processing (it also has the advantage of being easy to manufacture).

にすることは勿論である。In addition, in the above-mentioned embodiment, the inner wire is in the right-handed thread direction! Because the screws are screwed together, the direction of force used for one rotation is the left-handed screw direction. Therefore, the spiral groove 10 formed on the outer periphery of the first oil presser 11 has a left-handed thread direction. However, when using an inner wire threaded in the left-hand thread direction, it is not possible to form the first oil retainer in a spiral shape in the right-hand thread direction to obtain the same effect as above. Of course.
