PROBLEM TO BE SOLVED: To provide a bearing body mounting structure for a chair in which work for mounting a bearing body to a supporting frame of a chair body is facilitated and further, in the state where the bearing body is mounted to the supporting frame, a burden in a fastening portion between the supporting frame and the bearing body with deformation of the supporting body caused by a load can be reduced without impairing flexibility of the bearing body formed from an elastic member such as a synthetic resin.SOLUTION: As a bearing body formed from an elastic member, a seat plate 12 is slid in one direction, one front side of the seat plate 12 is fixed and held to a seat frame by fastening a bolt or the like through a mounting hole 17, and remaining three right, left and rear sides are held so as to hold an engage member of the seat frame with L-shaped and outwardly opening four lock pieces 12a, 12b protruding downwards from a rear side of the seat plate 12. Therefore, the seat plate 12 is mounted to the seat frame, and the lock pieces 12a, 12b are moved downwards and towards the center of the seat plate 12 by a load in seating. |
