输入圆盘(28)、离合器圆盘(38)和波形垫圈(56)都安装到输出轴(12)以形成电动机设备(90)的输出轴部件(10)。

An input disk (28), a clutch disk (38) and wave washers (56) are installed to an output shaft (12) to form an output shaft assembly (10) of a motor apparatus (90).

波形垫圈（56）施加抵抗力，以抵抗离合器圆盘（38）从输 入圆盘（28）与离合器圆盘（38）连接以一起旋转的连接状态的轴向运 动。

The wave washers (56) apply a resistive force against axial movement of the clutch disk (38) from a coupled state, at which the input disk (28) is coupled with the clutch disk (38) to rotate together.
