Description
本例では、以上のように、循環部品5の円周方向両側の端部に備えられた固定部19ごとに、1対の係合凸部26を1対の係合凹部16にそれぞれ係合させることで、ナット3に対する循環部品5の径方向(外側及び内側)及び軸方向のそれぞれの変位を不能とし、循環部品5をナット3に固定している。このため、ナット3に対する循環部品5の径方向及び軸方向のそれぞれの位置決めが図られる。また、循環部品5ごとに4つの係合凸部26が4つの係合凹部16に係合するため、循環部品5が本体部18の中心軸回りに回転することが防止される。
In this example, as described above, the pair of
本発明を実施する場合に、循環部品を合成樹脂製とすることもできる。この場合には、合成樹脂として、たとえばポリアミド66樹脂に、グラスファイバーを適宜加えた繊維強化ポリアミド樹脂材料を使用することができる。また、必要に応じて、ポリアミド樹脂に、非晶性芳香族ポリアミド樹脂(変性ポリアミド6T/6I)、低吸水脂肪族ポリアミド樹脂(ポリアミド11樹脂、ポリアミド12樹脂、ポリアミド610樹脂、ポリアミド612樹脂)を適宜加えることで、より耐水性を向上させることもできる。循環部品を合成樹脂製とする場合には、固定部に備える係合凸部を、ナットの取付凹溝に備えられた係合凹部に対して、スナップフィット式に係合させることができる。 When carrying out the present invention, the circulation part can also be made of synthetic resin. In this case, as the synthetic resin, for example, a fiber-reinforced polyamide resin material obtained by appropriately adding glass fiber to polyamide 66 resin can be used. In addition, if necessary, the polyamide resin, amorphous aromatic polyamide resin (modified polyamide 6T / 6I), low water absorption aliphatic polyamide resin (polyamide 11 resin, polyamide 12 resin, polyamide 610 resin, polyamide 612 resin) Water resistance can be further improved by adding it appropriately. When the circulation component is made of synthetic resin, the engaging projection provided on the fixing portion can be engaged with the engaging recess provided in the mounting groove of the nut in a snap-fit manner.
