Abstract

　円周方向のガタの抑制を図ることができ、しかも、ハブ輪と等速自在継手の外側継手部材との連結作業性に優れるとともに、ハブ輪と等速自在継手の外側継手部材との嵌合が安定して強度的にも優れた車輪用軸受装置及びこのような車輪用軸受装置を用いたアクスルモジュールを提供する。 　外側継手部材の軸部の外径面とハブ輪の孔部の内径面とのどちらか一方に軸方向に延びる凸部を設ける。凸部を軸方向に沿って他方に圧入し、この圧入によって他方に凹部を形成する。これによって、凸部と凹部との嵌合接触部位全域が密着する凹凸嵌合構造を構成する。凸部の少なくとも圧入開始端部の硬度を凹部形成部位の硬度よりも高くする。硬度差をＨＲＣで２０以上とする。
