Claims

[Claims for Utility Model Registration] 1. A pair of substantially half-ring-shaped inner supports is provided with a joint at one end thereof, and the joints of each inner support are connected to each other by a ring on both of the inner supports. An inner support device for a tire chain, characterized in that it is connected to a joint shaft so as to be openable and closable via a resilient means that applies resilient force to the closing side and a joint shaft. 2 A crimping protrusion is provided on the surface between the mounting piece at the proximal end of each fitting and the joint plate at the distal end, while a protrusion for crimping is provided on the surface between the mounting piece at the proximal end of each fitting and the coupling plate at the longitudinal center. 2. The inner side support device for a tire chain according to claim 1, further comprising a pressure protrusion provided on the surface between the stop hole and the stop hole.
