The present invention provides a brake device for a power rotary seat, which can improve operation stability and suppress generation of operation noise without play in the rotation direction when the rotary seat is operated, and comprises: a brake ring connected to a rotary fixing part; the brake wedge is connected with the rotating part; a brake roller and a brake spring provided in a wedge space formed between the inner peripheral surface of the brake ring and the outer peripheral surface of the brake wedge; an unlocking block provided to rotate the brake wedge in a direction in which clamping by the brake roller in the wedge space portion is released; a worm shaft for receiving the rotation torque input from the drive motor for the rotation of the unlocking block; and a worm wheel which is arranged between the worm shaft and the unlocking block and is shifted by reducing the rotation speed of the drive motor.

    本发明提供在转动座椅工作时不存在旋转方向游隙而能够提高动作稳定性且能够抑制工作噪音的产生的动力转动座椅的制动装置,构成为,包含:制动环,与转动固定部连接;制动楔,与转动旋转部连接;制动辊和制动弹簧,设置在形成于制动环的内周面与制动楔的外周面之间的楔子空间部;解锁块,设置为使制动楔向解除楔子空间部中的基于制动辊的夹紧的方向旋转;蜗杆轴,为了解锁块的旋转,接受从驱动电机输入的旋转扭矩;以及蜗轮,在蜗杆轴与上述解锁块之间,对基于驱动电机的旋转速度进行减速来转移。
