Description of the Related Art A shock absorber equipped with a manual vehicle height adjustment device is known as one type of shock absorber that is incorporated into the suspension of a vehicle such as an automobile. A manual vehicle height adjustment device generally includes a nut that is screwed into a male thread formed on the outer periphery of the outer shell of the shock absorber body and abuts the spring lower seat at its upper end, and rotates the nut relative to the shock absorber body. By moving the spring lower seat up and down, the spring lower seat is moved up and down.

ることができなくなることがある。 However, in such a conventional manual vehicle height adjustment device, the shock absorber is easily exposed to muddy water and dust, and muddy water and the like can easily enter the screw engagement part between the shock absorber body and the nut, so the nut cannot be rotated. It may become difficult to rotate the nut, or the nut may rust on the shock absorber body, making it impossible to rotate the nut.
本考案は、従来の手動式車高調整装置に於ける
上述の如き不具合に鑑み、かかる不具合を生じる
ことがないよう改良されたシヨツクアブソーバの
手動式車高調整装置を提供することを目的として
いる。 In view of the above-mentioned problems with conventional manual vehicle height adjustment devices, the object of the present invention is to provide a manual vehicle height adjustment device for a shock absorber that is improved so that such problems do not occur. .

セクタギヤを前記回動軸線の周りの任意の回動位
置に固定する手段とを有するシヨツクアブソーバ
の手動式車高調整装置によつて達成される。 This object is achieved, according to the present invention, by a manual height adjustment device for a shock absorber which comprises: a spring seat supported around a shock absorber body so as to be movable back and forth along its axis; a sector gear supported on the shock absorber body so as to be rotatable about a rotation axis substantially perpendicular to said axis and having teeth arranged along an arc line around the rotation axis; a cam which is integral with the sector gear and engages with the spring seat; a pinion which meshes with the teeth of the sector gear; and means for fixing the sector gear at any rotational position around the rotation axis.
かかる構成によれば、スプリングシートを上下

回動させるピニオンと歯車係合しており、従来の
手動式車高調整装置の如き目の細かいねじ係合に

ヨツクアブソーバに泥水などがかかつた場合にも
セクタギヤがその回動軸線の周りに回転できなく
なることはなく、従つてシヨツクアブソーバの車
高調整を確実に実施することができる。 According to this configuration, the sector gear that integrally has a cam that moves the spring seat up and down is engaged with a pinion that rotates the sector gear, and is not suitable for fine screw engagement as in conventional manual vehicle height adjustment devices. In comparison, it has a greater tolerance for muddy water, etc., so even if the shock absorber gets wet with muddy water, the sector gear will not become unable to rotate around its rotational axis, and therefore the vehicle height of the shock absorber can be adjusted reliably. can be implemented.

いる。 FIG. 1 is a front view showing one embodiment of a manual vehicle height adjustment device according to the present invention, and FIG. 2 is an enlarged partial sectional view taken along the line - in FIG. 1. In these figures, 1 indicates the shock absorber body. A lower seat 3 supporting the lower end of a suspension spring 2 is supported by the shock absorber body 1 so as to be movable back and forth along an axis 4. Further, a shaft 5 having a male thread at one end is fixed to the shock absorber body 1 at its base portion 6 by welding. The axis 7 of the shaft 5 extends perpendicularly to the axis 4 of the shock absorber body 1.

せられることが好ましい。 A sector gear 8 is rotatably supported on the shaft 5 around an axis 7. The sector gear 8 has a plurality of teeth 9 provided along an arc line around the axis 7, and is connected to the base portion 6 via a spring washer 11 by a nut 10 that is screwed into a male thread provided on the shaft 5. By being pressed against it, it can be fixed at any rotational position around the axis 7. Although not shown in the figure, in order to prevent muddy water from entering between the male thread of the shaft 5 and the nut 10, a rubber cap or the like is provided at the end of the shaft 5 or the nut 10 to cover them. Preferably, it is covered.

得るようになつている。 A cam 12 is integrally provided on the sector gear 8, and a cam surface 13 of the cam 12 engages with a lower end 14 of the lower seat 3. The cam surface 13 has an outer shape that allows the lower seat 3 to move up and down along the axis 4 when the sector gear 8 is rotated about the axis 7 . A pinion 15 meshes with the teeth 9 of the sector gear 8. The pinion 15 is press-fitted into a square section 19 of a shaft 18 that is rotatably supported around an axis 17 by a bearing member 16 that is fixed to the shock absorber body 1 by welding. It is designed to be able to rotate around 17.
