振動吸収装置に関する。[Detailed description of the invention] The present invention is a bushing cable that is used for remote control mechanisms of mechanical devices such as vehicles, and is composed of a flexible outer tube and an inner cable that is slidably inserted into the outer tube. It relates to a vibration absorption device.

突出している。In a conventional push-pull cable, as illustrated in FIG. 1, a hub b is fixed to the end of a flexible outer tube a, and a sleeve d is attached to the tip of the hub b through a bending joint C. A rod f is fixed to the end of the inner cable e which is connected to the outer tube a and is slidably fitted into the outer tube a, and the end of the rod f protrudes from the sleeve d.

され、水分、塵埃などの侵入を防止している。A bellows-shaped dustproof boot i made of an elastic material such as synthetic rubber is attached around the casing and the bending joint C, and a seal j made of an elastic material such as synthetic rubber is fitted to the tip of the sleeve d. It prevents the intrusion of moisture, dust, etc.

運転者に不快感を与えるばかりでなく、騒音を生じたり
、ナラ）ｇｎｈが緩んだり、さらには屈曲継手Ｃの接触
部が摩耗する等の不具合が生ずる。However, when this push-pull cable is used, for example, in a remote control mechanism for a vehicle transmission, engine vibrations are transmitted to the rod f via the operating piece m, causing the sleeve d and the inner cable e to vibrate. However, the shift lever connected to the other end of the inner cable e vibrates finely, which not only causes discomfort to the driver, but also causes noise, loosens the hinge, and even damages the contact part of the bending joint C. This may cause problems such as wear.
しかるに、スリーブｄはシールｊを介してロッドｆに対
して半径方向には強固に結合されているため、ロッドｆ
が半径方向に振動すると、スリーブｄは屈曲継手Ｃを中
心として首振り振動を生ずる。However, since the sleeve d is firmly connected to the rod f in the radial direction via the seal j, the rod f
When the sleeve d vibrates in the radial direction, the sleeve d vibrates around the bending joint C.
そこで、屈曲継手Ｃの屈曲性を損なわないようにして、
スリーブｄの振動を吸収するようにすれば、ロッドｆの
振動が抑制され、インナケープルｅに伝わる振動も減少
するのである。Therefore, in order not to impair the flexibility of the bending joint C,
By absorbing the vibrations of the sleeve d, the vibrations of the rod f are suppressed and the vibrations transmitted to the inner cable e are also reduced.
