Abstract: PURPOSE: A journal foil bearing with a noncorrugated bump foil and a motor with the same are provided to form the bump foil with the small difference of out-of-roundness using the noncorrugated bump foil. CONSTITUTION: A journal foil bearing comprises a holding member(110), a top foil(120), and a bump foil(130). The holding member comprises a cylindrical opening part(101) for receiving a shaft and is extended in one direction. The top foil is received in the cylindrical opening part and is formed along the inner circumference of the holding member. The bump foil without corrugation is arranged between the top foil and the holding member to surround the top foil.
