Description
車両用ハブユニットにおいて、外輪部材と内輪部材との間に形成される転動体配置空間の車両アウタ側を封止する車両アウタ側摺動シール機構が、外輪部材の内周面に嵌合する筒状嵌着部と、該筒状嵌着部の車両アウタ側端縁からラジアル方向内向きに延出する環状のシール支持部とからなる金属スリンガと、該金属スリンガのシール支持部の車両アウタ側主表面に一体化されるとともに、内輪部材の外周面に摺接する弾性材料からなるシール部とを有し、さらに、
シール支持部を覆う該シール部のラジアル方向外周縁には、筒状嵌着部の外周面をアキシャル方向に覆う延長被覆部が弾性材料により一体形成され、金属スリンガの筒状嵌着部が当該延長被覆部により覆われた状態で外輪部材の内周面に圧入されるとともに、外輪部材の内周面には、圧入される該延長被覆部の一部を弾性復帰させつつ迎え入れる凹部が形成されるとともに、
凹部は、外輪部材の内周面において、延長被覆部の圧入方向に向けて連続的に縮径する溝底面を有したくさび断面形状を有する溝状に形成されていることを特徴とする。
