FILLING STRUCTURE FOR ROAD BRIDGE EXPANSION DEVICE
To provide a filling structure for a road bridge expansion device in which a filling member can be arranged in an irregular gap only when it is necessary while suppressing the increase in the number of components and the weight, and abrasion along with the running of a vehicle is reduced to provide excellent durability while ensuring the smooth running of a two-wheeled vehicle.SOLUTION: As shown in Fig. 2(A), in the state where a gap S becomes smallest, a vertical displacement part 16A is located to be displaced in the most lowered position. Along with this, a filling body 3204 is also located to be displaced in the most lowered position, so that the filling body 3204 is located at the position with a distance downward the gap S between the mutually-opposed lateral sides of a v-shaped protrusion 28 (between lateral apical surfaces 2006B). As shown in Fig. 2(C), when the gap S becomes largest, the vertical displacement part 16A is located to be displaced in the most raised position. Along with this, the filling body 3204 is also located to be displaced in the most raised position so as to be located on the top of the gap S between the mutually-opposed lateral sides of the v-shaped protrusion 28 (between lateral apical surfaces 2006B) to fill a part of the gap S.SELECTED DRAWING: Figure 2
【課題】部品点数の増加および重量増を抑えつつ、必要な場合にのみ凹凸状の隙間に間詰め部材を配置でき、二輪車の円滑な走行を確保しつつ車両の走行に伴う磨耗を低減し、耐久性に優れる道路橋伸縮装置用間詰め構造を提供すること。【解決手段】図２（Ａ）に示すように、隙間Ｓが最も小さくなった状態では、上下変位部１６Ａは最も下方に変位した位置となり、これに伴い間詰め本体３２０４も最も下方に変位した位置となり、間詰め本体３２０４は、Ｖ字状凸部２８の互いに対向する側部間（側部先端面２００６Ｂ間）の隙間Ｓの下方に離れた箇所に位置する。図２（Ｃ）に示すように、隙間Ｓが最も大きくなった状態では、上下変位部１６Ａは最も上方に変位した位置となり、これに伴い間詰め本体３２０４も最も上方に変位した位置となり、Ｖ字状凸部２８の互いに対向する側部間（側部先端面２００６Ｂ間）の隙間Ｓの上部に位置し、隙間Ｓの一部を塞ぐ。【選択図】図２
