    • A disclosed flange member includes a press-fitted portion to be press-fitted in an axial end-opening portion of a hollow and cylindrical sleeve member; an axle opening portion including an axle opening into which a shaft member is inserted when the press-fitted portion is press-fitted in the end-opening portion; and a linking portion extending in a direction parallel to a circular cross section of the sleeve member and connecting the axle opening portion to the press-fitted portion. The linking portion includes a stress-absorbing portion that is deformed so as to absorb stress to which an outer peripheral surface of the press-fitted portion is subjected upon contact with an inner peripheral surface of the sleeve member when the press-fitted portion is press-fitted in the end-opening portion, thus preventing the stress from being transmitted to the axle opening portion via the linking portion.
    • 所公开的凸缘构件包括压配合部分,该压配部分压配合在中空和圆柱形套筒构件的轴向端部开口部分中; 所述车轴开口部包括车轴开口,当所述压配合部压配合在所述端部开口部时,所述轴构件插入到所述轴孔中; 以及连接部,其在与所述套筒构件的圆形截面平行的方向上延伸并将所述车轴开口部连接到所述压入部。 连接部分包括应力吸收部分,该压力部分被变形以吸收当按压配合部分被按压时压配部分的外周面与套筒部件的内周面接触时受到的应力 设置在端部开口部分,从而防止应力通过连接部分传递到车轴开口部分。
