PURPOSE: A spherical bearing is provided to easily separate an upper plate by forming a structure for bolt coupling in a part protruded on one side of the upper plate. CONSTITUTION: A spherical bearing includes a lower plate(22), an upper plate(23), and a side block(38). The lower plate is fixed to an upper surface of a bridge post and includes a pair of fixed blocks(37) protruded upwardly from a side. The upper plate is mounted on the lower plate and comprises one or more protrusions(43), a main body, a pair of first hooking units(41) for limiting the right/left displacement of the upper plate, and the second hooking units for limiting the up/down displacement of the upper plate. |
