    • PROBLEM TO BE SOLVED: To provide a torque transmission joint 15a including a buffer member 18a whose moldability can be improved and whose visibility from the outside can be improved.SOLUTION: A buffer member 18a is molded into a circular ring plate shape as a whole by injection-molding an elastic material such as rubber. Driving side insertion holes 29 and 29 and driven side insertion holes 30 and 30 are formed alternately with respect to a circumferential direction in a diametrical middle portion of the buffer member 18a while these holes each axially penetrate the buffer member. Driving side arm parts 21a and 21a provided in a driving side transmission member 16a can be inserted into the driving side insertion holes 29 and 29 without play, the driving side transmission member 16a being one of driving side and driven side transmission members 16a and 17a which are arranged in both axial ends respectively with the buffer member 18a interposed between the transmission members. Driven side arm parts 23a and 23a provided in the driven side transmission member 17a can be inserted into the driven side insertion holes 30 and 30 without play.
    • 要解决的问题:提供一种包括缓冲构件18a的扭矩传递接头15a,该缓冲构件18a的成形性能得到改善,并且可以改善其从外部的可视性。解决方案:缓冲构件18a整体由圆环形板形状整体由 注塑成型橡胶等弹性材料。 驱动侧插入孔29,29和从动侧插入孔30,30相对于缓冲部件18a的直径中央部的周向交替地形成,而这些孔各自轴向贯通缓冲部件。 设在驱动侧传动部件16a上的驱动侧臂部21a,21a能够无间隙地插入驱动侧插入孔29,29中,驱动侧传动部件16a是驱动侧和从动侧传递部件16a,17a之一 分别布置在两个轴向端部,缓冲构件18a分别设置在传动构件之间。 设置在从动侧传动部件17a中的被驱动的侧臂部件23a和23a能够在不起动的情况下插入从动侧插入孔30和30。
