Claims

[Scope of Claim for Utility Model Registration] (1) A point heater that heats the rail section on which points are installed to prevent snow from accumulating or freezing at the points, which extends over a certain length along the rail installation direction. a housing that is supported by the base of the side of the rail on which the point is installed, has an opening/closing lid on the top surface, and has an opening on the side of the rail; A point heater comprising: a heating element that emits a plurality of flames along the rail arrangement direction and heats a side surface of the rail from an opening with each flame. (2) The opening/closing lid of the above-mentioned casing is opened/closed with the rotation center on the side of the rail while being supported by the rail, and furthermore, the opening/closing lid is rotated from the outside of the rail to the side of the rail in the closed state. The point heater according to claim 1, which is formed to be inclined upwardly toward the utility model. (3) The point heater according to claim 2, wherein the side surface of the rail of the opening/closing lid approaches and protrudes upward from the side surface of the rail when the lid is closed.
