ワツシヤである請求項１記載の合成枕木。[Scope of Claim for Utility Model Registration] (1) The main body of the sleeper is composed of columns of hard resin foam reinforced with long fibers buried in the longitudinal direction, and the mounting bolts fitted into the main body of the sleeper are attached to the ground. In synthetic sleepers that are attached to side supports and are used by fastening the rails to the rail fastening parts provided on the surface of the sleeper body, the rails are attached between the rail fastening parts and the mounting bolt fitting parts on the surface of the sleeper main body. A synthetic sleeper characterized in that a signal current interrupting member is provided to interrupt leakage of the transmitted signal current to the mounting bolt side. (2) The signal current interrupting member is made of an electrically insulating paint having a coefficient of friction smaller than that of the surface of the sleeper body, which is applied between at least the rail fastening portion and the mounting bolt fitting portion on the surface of the sleeper body. The synthetic sleeper according to claim 1, which is a coating film. (3) A claim in which the signal current interrupting member is an obstacle made of an electrically insulating material installed in a convex shape between the rail fastening part and the mounting bolt fitting part on the surface of the sleeper body so as to separate the two. Synthetic sleeper according to item 1. (4) The synthetic sleeper according to claim 1, wherein the signal current interrupting member is an electrically insulating washer provided on the surface of the sleeper body for the mounting bolt.
