PROBLEM TO BE SOLVED: To provide a fastening device between a rail and a sleeper, the device that is structured to receive a live load to the rail received from a wheel by the bottom of the rail and to sandwich the rail with a left and a right claws in the traveling of a railway vehicle, is provided with both of the reduction effect of deviation of a rail gauge and the effect of creeping stopper (anti-slip), and in which, conventionally, when the rail is fixed to the sleeper by using a spring-type fastening device, the rail is fixed while being pressed down to the sleeper by a steel spring, and therefore, the deviation may gradually be caused in the rail gauge when the railway vehicle passes the rail frequently every hour and every day.SOLUTION: A fastening device of the present invention is structured to directly receive a load of a rail, even if the rail is fixed to the sleeper like a conventional fastening device. Accordingly, a live load or a wheel load of the vehicle via the rail is directly transmitted from a wheel to the rail, from the rail to the fastening device, and also, from the fastening device to the sleeper, and the device is structured to conversely use the friction generated in each place. Consequently, the friction of the ground plane of each place is used as a supporting force, and the pitching and rolling motion caused by the passage of the vehicle is moderated and transmitted, and thereby the device can be provided and used as services for reducing and preventing the deviation of the gauge.
【課題】従来は、バネ式の締結装置を使用してレールを枕木に固定したとき、レールをスチールバネで枕木に押さえる状態で固定をするため、毎時、毎日頻繁にレールを鉄道車両が通過することで徐々にレールの軌間に狂いが生じることがあった。【解決手段】 これまでの締結装置のようにレールを枕木に固定をしても、レールの荷重を締結装置が直接受ける構造にすることで、レールを通過する車両の活荷重が車輪からレールへ、レールから締結装置へ、又、締結装置から枕木へと輪荷重が直接伝わり、その各場所に発生する摩擦を逆に利用する構造とすることで、各場所の接地面の摩擦を支持力として利用し、車両の通過により生じるねピッチング運動やローリング運動を緩和させ伝えることで、軌間の狂いを減少させ、又、防止することが出来るサービスとして提供し使用する事が出来る。【選択図】図１
