To provide a cushion member which facilitates mounting work thereof on a road support.

The cushion member 9 is for use in a fixing structure which functions to fix the road support 1 with a base portion 2 having fixing holes formed therein, to a predetermined location, and has rod-like fixing members 7 inserted into the fixing holes, each fixing member 7 having a fastening portion 8 for applying a fastening force to the base portion 2. The cushion member is inserted into each fixing member 7 when the fixing member 7 is inserted into the fixing hole, so as to be interposed between the fastening portion 8 and the base portion 2, and upon application of a load to the road support 1, it functions to cushion the load applied to the fixing member 7. The cushion member is formed of a cylindrical portion 91 into which the fixing member 7 is insertable, and a collar portion 92 formed on either one end or the other end of the cylindrical portion 91, and having an outer diameter 3 larger than the outer diameter 1 of the cylindrical portion 91. Further the cylindrical portion 91 and the collar portion 92 are connected together in one body.
