Claims

[Claims for Utility Model Registration] A sector, an operating lever rotatably supported by the sector and connected at one end to the parking brake, and a rotation center of the operating lever at the other end. a parking brake lever mounted so as to be rotatable about an axis parallel to the axis; and a parking brake lever provided in the sector so as to be rotatable around a central axis of rotation of the operating lever, independently of the operating lever. a second gear integrally disposed on the barking brake lever around the rotation center of the parking brake lever and meshing with the first gear; and a second gear between the parking brake lever and the operating lever. provided between the two levers, and prevents the relative rotation between the two levers while the relative moment between the two levers is less than a predetermined value, and allows the relative rotation when the value exceeds the value. a relative rotation limiting device that engages with the first gear to allow the first gear to rotate in the brake operation direction of the operating lever;
a ratchet pawl device that prevents the first gear from rotating in the opposite direction and releases the blocking of the first gear from rotating in the opposite direction when the parking brake lever is returned to a non-operating position; When the relative rotational moment between the parking brake lever and the operating lever exceeds the predetermined constant value according to the operating force applied to the lever, the operating force is applied to the lever at a higher lever ratio than before. A parking brake operating device characterized by transmitting information to a parking brake.
