PURPOSE: A bearing bush is provided to reduce a friction contact section by supporting a normal force and a twist load applied to a rotary shaft in rotating a rotary body. CONSTITUTION: A bearing bush(20) includes a body, a plurality of inner planar parts(35), and one inner curved part(37). The body has a ring shape. A through hole(32) is formed inside the body. One end of a rotary shaft(11) of a rotary body is inserted to the through hole. The inner planar parts are formed in one side of an inner circumference of the body, are adjacently arranged each other, and are arranged in a region in which a load of the rotary body is operated. The inner curved part is formed in the other side of the inner circumference of the body, and is connected to the inner planar parts. A distance from each inner planar part to the inner curved part is larger than a diameter of the rotary shaft.
