PROBLEM TO BE SOLVED: To easily suppress abrasion at a contact portion of a boot and a shaft by simple means.SOLUTION: A constant velocity universal joint includes an outside joint member 12, and an inside joint member 13 configured to transmit rotational torque with angular displacement allowed via a ball 14 between itself and the outside joint member 12, wherein between an opening part 11 of the outside joint member 12 and a shaft 17 extending from the inside joint member 13, a boot 23 is mounted. On a surface of a contact portion of an outer peripheral surface 30 of the shaft 17 and an inner peripheral surface 29 of the boot 23, a flock part 31 is formed, where many fibers are flocked.SELECTED DRAWING: Figure 1 【課題】 簡便な手段によりブーツとシャフトとの接触部位での摩耗を容易に抑制する。【解決手段】 外側継手部材１２と、その外側継手部材１２との間でボール１４を介して角度変位を許容しながら回転トルクを伝達する内側継手部材１３とを備え、外側継手部材１２の開口部１１と内側継手部材１３から延びるシャフト１７との間にブーツ２３を装着した等速自在継手であって、シャフト１７の外周面３０とブーツ２３の内周面２９との接触部位の表面に、多数の繊維が植設された植毛部３１を形成する。【選択図】 図１
