A spherical slide bearing has an outer ring and an inner ring slidably held in the inner ring. In the inner ring is inserted a pin so as to be slidable in the circumferential direction of the inner ring, the pin having a grease supply flow path that passes the inside of the ring to open in the outer peripheral surface of the ring. Further provided in the inner ring is a communication flow path for allowing the gap between the inner ring and the pin and the gap between the inner ring and the outer ring to communicate with each other. The entrance of the communication path is provided at a position into which grease, flowing out from the exit of the grease supply flow path, enters after flowing through the gap between the pin and the inner ring, along substantially the entire length in the axial direction of the pin.
