Claims

1. a plurality of anti-slip members arranged on a floor plate member interposed between an automobile tire and a road surface, each of the anti-slip members protruding from the front and back sides of the floor plate member, each of the anti-slip members having anti-slip irregularities formed on both the front and back end surfaces thereof; a fixing mechanism for fixing each of the anti-slip members to the floor plate member, wherein the fixing mechanism comprises: the anti-slip members formed in a planar cross shape, the floor plate member having a cross groove portion into which the planar cross-shaped anti-slip members can be inserted, a rotating operation member for fixing the anti-slip members to the floor plate member is rotatably provided, and a bridge member for restricting the rotation of the rotating operation member is provided.

2. 2. An automobile tire extractor according to claim 1, wherein the anti-slip member is made up of two members, a first member and a second member, and slit grooves that can be fitted into each other are formed on the opposing end surfaces of the first member and the second member, and the anti-slip member is formed into a planar cross shape by fitting the slit grooves of the first member and the second member together.

3. Fitting grooves are formed on both outer end surfaces of the one member and the other member of the anti-slip member, fitting holes that can be rotatably fitted into the fitting grooves are formed in the turning operation member, insertion protrusions that can be inserted into the cross grooves of the floor plate member are formed on the front sides of the fitting grooves of the one member and the other member of the anti-slip member, and blocking protrusions that cannot be inserted into the cross grooves of the floor plate member are formed on the back sides of the fitting grooves of the one member and the other member of the anti-slip member, and the inner peripheral surfaces of the fitting holes of the turning operation member are formed on the inner peripheral surfaces of the fitting holes of the one member and the other member of the anti-slip member.

3. An automobile tire escape tool according to claim 2, characterized in that a groove portion into which the insertion convex portion of the front side portion can be inserted is formed to match the position of the cross groove portion, and by rotating the rotating operation member forward or backward, a selection operation can be performed to allow insertion of each insertion convex portion of the anti-slip member into each concave groove portion of the rotating operation member, or to prevent insertion of each insertion convex portion into each concave groove portion of the rotating operation member, and that the selection operation to prevent insertion prevents removal of the anti-slip member from the floor plate member.

4. 4. An automobile tire escape tool according to claim 3, characterized in that the piece member comprises a fitting base portion that can be fitted into the groove portion of the rotation operation member when the rotation operation member is selected to be unable to be inserted, and a fitting end portion that can be fitted into the V-shaped gap between the adjacent opposing surfaces of the front side portions of the one member and the other member of the anti-slip member.

5. 2. An automobile tire extractor according to claim 1, wherein said base plate member, said anti-slip member and said rotation operation member are made of paperboard.

6. 2. The automobile tire extractor according to claim 1, wherein the rotation operation member is formed in a laminated state from a paperboard material having the same thickness as the floor plate member.

7. 2. An automobile tire extractor according to claim 1, wherein the flat cross-shaped anti-slip member is disposed on the floor plate member at a position where a V-shaped corner of the anti-slip member faces the outer peripheral surface of the tire.

8. 2. An automobile tire extractor according to claim 1, wherein a plurality of anti-slip members are arranged in a scattered manner on said floor plate member.

9. 2. An automobile tire extractor according to claim 1, wherein said floor plate member is formed with a bent portion that enables said floor plate member to be bent.
