夹持机构、具有该夹持机构的无刷电机和具有该无刷电机的盘驱动装置
摘要：
本发明涉及一种夹持机构、具有该夹持机构的无刷电机和具有该无刷电机的盘驱动装置。爪件在其径向内表面处包括突起倾斜面，从而使弹性件沿轴向发生的变形最小化，该弹性件是螺旋弹簧。该突起倾斜面优选在爪件的尖端部处于轴向最低点时倾斜成大体垂直于中心轴，或者被倾斜成使其沿径向越朝内的部分在轴向上越低。根据该构造，该突起倾斜面使弹性件沿轴向发生的变形最小化。
摘要（英）：

A claw member includes at a radially inward surface thereof a protrusion inclined surface in order to minimize deformation occurring in an axial direction to an elastic member which is a coil spring.The protrusion inclined surface is preferably inclined, when a tip portion of the claw member is at an axially lowest point, to be substantially perpendicular to the central axis, or such that the further radially inward a portion thereof is the axially lower the portion is. By virtue of such configuration, the protrusion inclined surface minimizes deformation occurring to the elastic member in the axial direction.
