PROBLEM TO BE SOLVED: To provide a spherical bearing to eliminate a caulking process and improve the tensile strength of an outer ring. SOLUTION: A spherical bearing comprises an inner ring provided on an outer surface with a spherical trajectory surface, an outer ring provided on an inner surface with a spherical trajectory surface rotatably fitted in corresponding to the spherical trajectory surface of the inner ring; and a bolt radially extending such that an axis situated in one spot on the outer peripheral surface of the outer ring passes through a position above the outer ring axis. In this spherical bearing, an inner ring-contained groove 4 positioned on the axis of a bolt and in the opposite load direction of the inner ring is formed in the inner peripheral part on one side of the outer ring 2.
