PROBLEM TO BE SOLVED: To provide a bush bearing for slidingly supporting a shaft member such as a rack shaft with prescribed rigidity in the radial direction and with low frictional resistance in the shaft direction, and reducing a performance change in a heat history. SOLUTION: This bush bearing 1 has a cylindrical inner peripheral surface 3 for allowing the rack shaft 2 to slidingly contact in the shaft direction A, and has a slit 6 extending up to the other end surface 5 from one end surface 4 of the shaft direction A so that the inner peripheral surface 3 freely diametrally contracts, and has a bush body 10 having an annular circumferential directional groove 8 on a cylindrical outer peripheral surface 7 and an endless annular elastic member 11 installed in the circumferential directional groove 8 of the bush body 10 and having an outer diameter D2 larger than a diameter D1 of the outer peripheral surface 7 of the bush body 10.
