To closely fit a non-slip member to a tire and improve the traveling stability of a vehicle by providing an irregular part continued with corrugated sectional form on the inside surface and outside surface capable of being fitted to both side surfaces of the tire of a vehicle non-slip member.

A non-slip member 1 has an inside form having a required width preliminarily bent and formed so as to be capable of being fitted to the circumferential surface and both side surfaces of a tire by use of an elastic body such as rubber or a synthetic resin, and it has an irregular part 5 continued to both inside surfaces 2 with a corrugated sectional form, an irregular part 6 continued to both outside surfaces 3 with a corrugated sectional form, and horizontal slippage preventing projections 7 on both side end parts of a grounding surface part 4. Since both the inside surfaces 2 and both the outside surfaces 3 of the non-slip member 1 have the irregular parts 5, 6 continued thereto with the corrugated sectional forms, respectively, both the inside surfaces 2 of the non-slip member 1 can be easily bent along the angle part extending from both side terminal part of the circumferential surface of the tire to both the side surface and both the side surfaces, and installed to the tire in closely fitted state.
