Abstract
A spherical slide bearing has an outer ring and an inner ring slidably retained within the outer ring. A pin having a grease supply flow path extending through an interior thereof to open in an outer peripheral surface thereof is inserted into the inner ring so that the pin is circumferentially slidable, with the inner ring being equipped with a communication flow path establishing communication between a gap defined between the inner ring and the pin and a gap defined between the inner ring and the outer ring. The inlet port of the communication flow path is provided at a position where grease having flown out of an outlet port of the grease supply flow path flows after having flown through the gap between the pin and the inner ring substantially through the entire length in the axial direction of the pin.
