摘要： A rotation transmission device includes an inner ring provided on an input shaft, the outer ring, which is provided on an output shaft, rollers mounted between the inner periphery of the outer ring and the outer periphery of the inner ring, an electromagnet, as a driving source for moving a roller retainer, mounted at the end portion of the housing on the side of the input shaft, a first bearing mounted between the electromagnet and the input shaft, a second bearing mounted between the end portion of the housing on a side of the output shaft and the output shaft, and a third bearing mounted between the inner ring and the outer ring. The rotation transmission device further includes a fourth bearing configured to prevent inclination of the axes of the input shaft and the output shaft relative to each other.

摘要： A rotation transmission device is provided which includes, in its housing, an electromagnetic clutch, and a two-way clutch by which a first shaft and a second shaft are selectively engaged with, and disengaged from, each other. A rolling bearing is disposed at one axial end of the housing, and supports the second shaft and the housing. Locking arrangements prevent relative axial movement between the second shaft and the rolling bearing, and between the rolling bearing and the housing. A movement restricting arrangement is disposed at the other axial end of the housing, and restricting movement of the electromagnetic clutch toward the other axial end of the housing.

摘要： A rotation transmission device includes an electromagnetic clutch including an armature, a rotor having an outer tubular portion and an inner tubular portion, and an electromagnet. A bearing support tube is provided at the outer end surface of a core supporting an electromagnetic coil of the electromagnet. A bearing is mounted in the bearing support tube so as to be axially fixed in position and not to be pulled out of the bearing support tube. The small-diameter tubular portion is provided at the end of the inner tubular portion of the rotor, and press-fitted in the bearing such that the rotor and the electromagnet form a unit.

摘要： A rotation transmission device is provided in which an electromagnetic clutch selectively engages and disengages a two-way clutch configured to selectively perform and stop the transmission of torque between an input shaft and an output shaft. A spring holder fitted on the input shaft prevents rollers from axially moving. Spring holding pieces mounted to the spring holder are formed with respective engagement surface engaging with cam surfaces of the outer periphery of an inner ring such that the spring holder is rotationally fixed. Since it is not necessary to machine the input shaft just for the purpose of rotationally fixing the spring holder, it is possible to reduce costs.
摘要翻译：提供了一种旋转传动装置，其中电磁离合器选择性地接合和分离配置成选择性地执行和停止输入轴和输出轴之间的扭矩传递的双向离合器。安装在输入轴上的弹簧座防止滚轴轴向移动。安装在弹簧保持架上的弹簧保持件形成有与内圈的外周的凸轮表面接合的相应的接合表面，使得弹簧保持器旋转地固定。由于不需要仅仅为了旋转地固定弹簧保持器来加工输入轴，所以可以降低成本。
