Claims

[Scope of Claim for Utility Model Registration] (1) In addition to fixing the base of the parking brake lever, a support member is provided for pivotally supporting the operating shaft to which the end of the brake cable is attached to the cable attachment part, and the support member is engaged with the ratchet gear part of the support member. attaching an arm rod that supports a free parking brake ratchet pawl to a mounting shaft that supports a base of the parking brake lever;
A parking brake tensioning device comprising a tensioning cable whose one end is fixed to an actuating member whose end is rotatably attached to the mounting shaft, and the other end of which is connected to a tensioning cable drive mechanism. (2) In addition to fixing the base of the parking brake lever, a support member is provided for pivotally supporting the operating shaft to which the end of the brake cable is attached to the cable attachment part, and a parking brake ratchet pawl that can freely engage with the ratchet gear part of this support member is provided. The other end of the arm lever pivoted at one end is attached to a mounting shaft pivoted to the base of the parking brake lever, and the other end of the operating member whose end is rotatably attached to the mounting shaft is connected to the arm lever. A tightening ratchet pawl, whose base is pivotally supported on the connecting shaft, can be engaged with the ratchet gear portion, and the other end of the tightening cable, which has one end fixed to the operating member, is connected to the tightening cable. A parking brake tightening device connected to a drive mechanism.
