    • A device for transmitting rotational power from a rotational power source to a driven device having a drive shaft includes at least one elastic connecting member defining outer and inner peripheral surfaces. First and second holder members radially cooperate with each other to circumferentially hold the at least one elastic connecting member during normal operation to transmit the rotation, and are disconnected by the deformation of the at least one elastic connecting member when the torque on the drive shaft exceeds a predetermined cutoff torque level. A weakened portion is provided at least one of the first and second holder members. The weakened portion aids the deformation of at least one of the first and second holder members to reduce a torsional spring coefficient which is defined by the ratio of the relative rotational angle between the first and second holder member to the torque on the drive shaft.
    • 用于将旋转动力从旋转动力源传递到具有驱动轴的从动装置的装置包括限定外周面和内周面的至少一个弹性连接构件。 第一和第二保持器构件在正常操作期间彼此径向配合以周向地保持至少一个弹性连接构件以传递旋转,并且当驱动轴上的转矩超过时由于至少一个弹性连接构件的变形而断开 预定的切断扭矩水平。 设置有第一和第二保持器构件中的至少一个的弱化部分。 弱化部分有助于第一和第二保持器构件中的至少一个的变形,以减小由第一和第二保持器构件之间的相对旋转角度与驱动轴上的转矩之比确定的扭转弹簧系数。
