この考案は油圧緩衝器におけるピストンロツド
又は内筒外周とガイドブツシユとの間に生ずるク
リアランスを調整する装置に関する。[Detailed Description of the Invention] This invention relates to a device for adjusting the clearance generated between a piston rod or the outer circumference of an inner cylinder and a guide bush in a hydraulic shock absorber.

が難かしくコストが高かつた。 It is known that the smaller the clearance created between the piston rod or the outer circumference of the inner cylinder and the guide bush, the better the performance, as long as it does not affect its operation. In other words, if the clearance is large, this will cause backlash and deteriorate operability, and partial sliding of the guide bushing will increase surface pressure and impair durability. However, the dimensions of the piston rod or inner cylinder that determine the clearance and the dimensional accuracy of the guide bushing require extremely high accuracy (approximately 0.08 mm in diameter due to stacking tolerances), making manufacturing difficult and expensive.

グが縮径される構成となしたことを要旨とする。 In view of the above points, this invention proposes a device whose purpose is to make the clearance easily adjustable.A guide bush housing is fitted onto the guide bush, and a tapered portion is formed on the outer periphery of the guide bush housing. At the same time, a tightening bolt is internally fitted into the upper end of the cylinder or outer cylinder, and the inner periphery of the tightening bolt is shaped to match the tapered portion of the outer periphery of the guide bushing housing, and is slidably fitted. The main feature is that the diameter of the guide bushing housing is reduced when the tightening bolt is rotated and lowered.

勿論である。 A method for adjusting the clearance of the guide bushing in the device having the above configuration will be described. First, the lock nut 14 is loosened, and the tightening bolt 7 is turned and lowered. Due to the screw force of this tightening bolt 7, a force is applied downward as shown by the arrow.
Tapered portion 5 of guide bush housing 4
A force acts perpendicularly to the surfaces of a and 5b. This force generates a force that acts on the outer periphery of the guide bush 3 in the radial direction, that is, a component force. FIG. 2 is a cross-sectional view showing the main parts of the guide bush housing 4 and the guide bush 3.
are provided with notches a and b to facilitate diameter reduction, and each of the notches a and b are provided to ensure sealing performance.
The position of b has been shifted (180 degrees in Figure 2). Therefore, due to the component force acting in the direction of the arrow,
The guide bush housing 4 and the guide bush 3 are successively reduced in diameter, and the clearance c generated between the guide bush 3 and the fork pipe 1 is reduced to the limit that does not impair operability. . Once the clearance has been properly adjusted as described above, the lock nut 4 is tightened and fixed. Note that the cross-sectional shape of the guide bush housing is not limited to that shown in the embodiment, but may be the cross-sectional shape shown in FIG. 3, etc. Also, the piece 6 and the bottom case 2
There is no problem even if they are integrally molded. Although this embodiment has been described with respect to a front fork, it goes without saying that this invention can be applied to a simple type hydraulic shock absorber.

容易となりコストは低下する。 According to this invention, as described above, the diameter of the guide bushing is reduced within the elastic limit by the simple operation of rotating and lowering the tightening bolt.
Since the clearance with the piston rod or inner cylinder can be adjusted to a small value, there is no need to require extremely high dimensional accuracy of the piston rod or inner cylinder and the guide bush. Therefore, manufacturing and processing becomes easier and costs are reduced.
