A joint fixing structure of a joint device for a railway carriage is provided to prevent generation of a noise between a joint housing and a joint by having a plug to fix the joint to the joint housing and enhance production and assembly performance of related components. A joint fixing structure(1) of a joint device for a railway carriage comprises a spherical rubber joint(30), a joint housing(10), and a pair of circular plugs(40). The joint housing receives the spherical rubber joint and has a cylindrical hole. The circular plugs fix the spherical rubber joint by being coupled with both sides of the cylindrical hole of the joint housing. The circular plug has a ring unit(42) and an extension unit(43). The ring unit has a plurality of holes(41) at a predetermined width and is in contact with a side surface of the joint housing. The extension unit is in contact with a concave surface of the spherical rubber joint by being axially extended to an inside diameter of the ring unit and fixes the spherical rubber joint to the joint housing. |
