<P>PROBLEM TO BE SOLVED: To provide a tire anti-skid device which does not require work of adjusting the internal width of anti-skid bodies to be inlaid into a vehicle tire. <P>SOLUTION: There is provided the tire anti-skid device in which the anti-skid bodies each having a U-shaped cross-section are inlaid into a vehicle tire and several anti-skid bodies are evenly spaced in the peripheral direction of the tire and connected to each other in a circular manner, and each of the anti-skid bodies has a contact member 6 that comes in contact with the tire outside surface and that is disposed in the outside section of the anti-skid body and a contact member 6 that comes in contact with the tire inside surface and that is disposed in the inside section. A shaft 7 is attached to the outside section 2b or the inside section 2c of each of the anti-skid bodies, along the axial center direction of the tire T. The shaft is attached so as to be movable forward and backwards along the axial center direction of the tire. The contact members 6 are disposed on an inside ends of the shaft. Elastic members 9 providing forward propulsion are disposed on the shaft having contact members attached thereto. The contact members are pushed to the outside surface or the inside surface of the tire by the elastic force of the elastic members. When the outside surface or the inside surface of the tire with which the contact members have come in contact, moves to the side opposite from the contact members, the contact members move forward due to the elastic force of the elastic members. When the outside surface or the inside surface of the tire with which the contact members have come in contact, moves to the contact member side, the contact members move backward in resistance to the elastic force of the elastic members. <P>COPYRIGHT: (C)2013,JPO&INPIT |
