Abstract

　内周面に軸方向に延びる三本のトラック溝１２が形成され、各トラック溝１２の両側でそれぞれ軸方向に延びるローラ案内面１４を有する外輪１０と、半径方向に突出した三本の脚軸２４を有するトリポード部材２０と、トリポード部材２０の脚軸２４に回転自在に支持されると共に外輪１０のトラック溝１２に転動自在に挿入されてローラ案内面１４に沿って案内されるローラ３０と、脚軸２４とローラ３０との間に配設された複数の針状ころ４０とを備え、脚軸２４の外周面に、針状ころ４０を収容して底面２３ａが針状ころ４０の転動面となる凹溝部２３を周方向に形成し、凹溝部２３の半径方向基端側に内側鍔部２５を設けると共に半径方向先端側に外側鍔部２７を設け、内側鍔部２５および外側鍔部２７と凹溝部２３の底面２３ａとの間に形成された鍔面２５ａ，２７ａをテーパ状とし、そのテーパ角度を凹溝部２３の底面２３ａからの開き角で９０°より大きく、かつ、１４０°以下とする。
