    • PROBLEM TO BE SOLVED: To suppress wobbling without narrowing a slide clearance of bearings related to the improvement of a front fork.SOLUTION: A damper D comprises: an outer tube 10; an inner tube 11 which enters and leaves from the outer tube 10; a cylindrical clearance a formed between overlapped parts of the outer tube 10 and the inner tube 11; a pair of bearings 2A, 2B which are arranged in the cylindrical clearance a, and pivot the inner tube 11 so as to be capable of freely entering and leaving from the outer tube 10; and liquid which is accommodated in the cylindrical clearance a, and slides on slide faces of the bearings 2A, 2B. The damper also comprises narrowing means 3A which extends along the axial direction of the cylindrical clearance a, and narrows a cross section area of the cylindrical clearance a.
    • 要解决的问题:为了抑制摆动,而不会缩小与前叉的改进有关的轴承的滑动间隙。解决方案:阻尼器D包括:外管10; 从外管10进入和离开的内管11; 形成在外管10的重叠部分和内管11之间的圆柱形间隙a; 一对轴承2A,2B,其布置在圆筒形间隙a中,并且使内管11枢转以能够从外管10自由地进出; 容纳在圆筒形间隙a中的液体,并在轴承2A,2B的滑动面上滑动。 阻尼器还包括沿圆柱形间隙a的轴向方向延伸的变窄装置3A,并使圆柱形间隙a的横截面面积变窄。
