A low friction spherical bearing (21) capable of lowering the maximum value of a force necessary for moving the shaft (33) of a spherical bearing, comprising a housing (23), a storage body (43), and the shaft (33) having a spherical part (35), wherein the outer diameter or inner diameter of a seat (43) in a direction perpendicular to the operating direction of the shaft is reduced, and a pressure produced through the seat (43) between the spherical part (35) and the storage part (24) of the housing is reduced.
