Claims

[Claims for Utility Model Registration] In a parking brake in which the operating force of the parking brake lever is transmitted via a cable, a device that automatically adjusts the tension of the cable in accordance with the rotational operation of the parking brake lever. a connecting member to which an end of the cable is connected; and a guide member that is fixed to a side of the parking brake lever and guides the connecting member in a direction in which the cable is pulled in a non-rotatable manner about an axis. , an adjusting member having outer peripheral teeth and screwed onto the connecting member to prevent movement of the connecting member in the pulling direction; and a claw portion and an acting portion that are engageable in one direction with the outer peripheral teeth of the adjusting member. a rotary member that is rotatable relative to the parking brake lever about the same axis with a predetermined relative rotational resistance; When the amount of rotational operation of the brake lever exceeds a predetermined amount, the rotating member is rotated relative to the punching brake lever to cause the pawl portion and the outer tooth to slide relative to each other. , a stopper that rotates the adjustment member in a direction in which the rotation member is rotated relative to the parking brake lever when the parking brake lever is operated to the original position, and the tension of the cable is increased by the claw portion; An automatic cable tension adjustment device for a parking brake lever, comprising a member.
