To obtain a spherical joint which can simplify an oil drain structure of oil which has lubricated the spherical joint.SOLUTION: A spherical joint comprises an inner ring having a shaft, and an outer ring having an annular slide part encapsulating the inner ring and sliding with the inner ring, and formed with an opening part which is penetrated with the shaft of the inner ring. A high-pressure lubricant is supplied to the annular slide part. The opening part is covered with a cover, the outside and the inside of the opening part are blocked, an annular oil drain sump is formed between the cover and the inner ring, a circular oil drain sump is formed between the outer ring and the inner ring at an opposite side with the annular oil drain sump and the inner ring sandwiched therebetween, a communication oil passage for making the annular oil drain sump and the circular oil drain sump communicate with each other is formed at the inner ring, and an oil drain outlet is formed at either of the circular oil drain sump or the annular oil drain sump.SELECTED DRAWING: Figure 1 【課題】球面継手を潤滑した後の油の排油構造を簡素化できる球面継手を得る。【解決手段】球面継手は、軸を備える内輪と、内輪を内包すると共に内輪と摺動する円環状摺動部を有し且つ内輪の軸が貫通する開口部を形成している外輪と、を備え、前記円環状摺動部に高圧の潤滑油が供給される。前記開口部は、カバーで覆われて外部と内部が遮断され、カバーと内輪との間に円環状排油溜りが形成され、前記円環状排油溜りと内輪を挟んで反対側には前記外輪と前記内輪との間に円形排油溜りが形成され、前記円環状排油溜りと円形排油溜りとを連通する通油路が前記内輪に形成され、前記円形排油溜り或いは円環状排油溜りの何れかに排油出口が設けられている。【選択図】図１
