本考案は、車両用ボールジヨイントのダストブ
ーツの取付構造に関する。[Detailed Description of the Invention] The present invention relates to a mounting structure for a dust boot of a ball joint for a vehicle.
一般に自動車のボールジヨイントのダストブー
ツは、ボールジヨイントのロツド部分に固着され
た略つば状のリテーナに嵌着支持されている。と
ころがこのリテーナは、鉄板のプレス打ち抜きに
より製作され、周囲がシヤープエツジとなつてい
るため、ダストブーツと干渉してブーツを損傷さ
せる恐れがあつた。 Generally, a dust boot for a ball joint of an automobile is fitted and supported by a generally brim-shaped retainer fixed to a rod portion of the ball joint. However, since this retainer is manufactured by press punching an iron plate and has a sharp edge around its periphery, there is a risk of interference with the dust boot and damage to the boot.
特に、融雪期のサスペンシヨンのロアーアーム

れがあつた。このような不具合を防止するために
従来では、リテーナのプレス打ち抜き形状を変え
たり、シヤープエツジを機械加工したりする方法
があつたが、加工工程の増加、コストアツプ等を
招くという欠点があつた。 In particular, if the dust boot is pushed inward and dented due to ice buildup on the lower arm of the suspension during the snow melting season, the inner surface of the boot will interfere with the shear edge on the outer edge of the retainer, and vibrations during driving will also cause wear. In addition, there was a fear that cracks and damage would develop. In order to prevent such problems, conventional methods include changing the press punched shape of the retainer or machining the sharp edges, but these methods have the disadvantage of increasing the number of processing steps and increasing costs.
本考案の目的は、特にリテーナに機械加工を追
加することなく、前述のようなリテーナとの干渉
によるダストブーツの損傷を防止できるダストブ
ーツ取付構造を提供することにある。 An object of the present invention is to provide a dust boot mounting structure that can prevent damage to the dust boot due to interference with the retainer as described above, without particularly requiring additional machining of the retainer.
本考案は、車両用ボールジヨイントのロツド部
分に、外縁に丸みを形成した樹脂製のつば状部を
有するリテーナを固着し、該リテーナにボールジ
ヨイントを保護するダストブーツを嵌着支持して
成るものである。 In the present invention, a retainer having a resin collar with a rounded outer edge is fixed to the rod part of a ball joint for a vehicle, and a dust boot that protects the ball joint is fitted and supported on the retainer. It is what it is.
このような構成により、ダストブーツがリテー

との接触部分の機械加工を必要としない製造が容
易なリテーナを提供できるものである。 With this structure, even if the dust boot interferes with the retainer, the outer edge of the retainer is formed by a rounded resin, so damage to the dust boot can be prevented, and at least the flange-like part of the retainer that contacts the dust boot can be prevented. By making the retainer made of resin, it is possible to provide a retainer that is easy to manufacture and does not require machining of the contact portion of the retainer with the dust boot unlike in the case of an iron plate.

たリテーナ８に嵌着支持される。 The present invention will be described below based on an embodiment shown in the drawings. FIG. 1 shows a portion of an automobile suspension, particularly including a ball joint, and shows a lower arm 1 pivotally connected to a vehicle body (not shown), and a wheel (not shown). It consists of component parts such as a knuckle arm 2 that holds the body (not shown) and a ball joint 3 that connects these two parts. The dust boot 4 that protects the ball joint has its lower end attached to the lower arm 1.
The housing 5 of the ball joint is supported by, for example, a ring 6, and its upper end is fitted and supported by a retainer 8 which is fixed to the rod portion 7 of the ball joint by press fitting or the like.

ーツ嵌着部のシール性を低下させないようにした
ものである。 In this embodiment, the retainer 8 is itself integrally or integrally formed of resin, and has a collar 9, as shown in particular in FIG. A roundness 10 is provided. Next, another embodiment shown in FIG.
Only the collar portion 9 including the annular roundness 10 is made of resin,
The part 11 fixed to the rod part 7 is made of iron plate,
Both are integrally formed by means such as welding, so that the sealing performance of the dust boot fitting portion is not deteriorated.
このような構成において、第２図に示すよう

となく容易に丸み１０を形成することができる。 In such a configuration, as shown in FIG. 2, even if the dust boot 4 is dented due to icing 12 or the like on the lower arm 1 and its inner surface interferes with the collar 9 of the retainer, at least the collar is made of resin. Since the boot is made of aluminum and has an annular radius 10 formed on the outer edge, damage to the boot can be prevented. Further, since the brim portion is made of resin, the roundness 10 can be easily formed without any special machining.
