Abstract
【解決手段】複列の円すいころ9が保持器7、8を介して転動自在に収容された背面合せタイプの複列の円すいころ軸受からなる車輪用軸受装置において、アウター側の軸受列が、円すいころ9を案内する大鍔4dが内輪5に形成されておらず、外方部材4における外輪転走面4aの大径側に一体に形成されていると共に、この軸受列の保持器7が内抱き型で、保持器7の内径が内輪5の内側転走面5aに僅かな径方向すきまを介して対峙していると共に、インナー側の軸受列の保持器8が外抱き型で、保持器8の外径が外側転走面4bに僅かな径方向すきまを介して対峙し、この保持器8の小径側に保持器7の小径側が一部内挿されているので、円すいころ9の小径側を延長させて長く設定しても保持器7、8同士の干渉はない。
