Claims

[Claims for Utility Model Registration] (1) An operating lever for operating the parking brake; a fixed sector rotatably supporting the operating lever and having locking teeth on its outer periphery; a claw member that is freely supported and can be engaged with the sector; an operating knob that is retractably disposed on a grip portion of the operating lever; the operating knob is fixed to one end, and movement of the operating knob causes the claw member to engage with the sector; A parking brake operation comprising: a rod that rotationally displaces a member between an engaged position and a non-engaged position; and a biasing member that biases a pawl member to be constantly engaged by protruding and biasing the operation knob. A parking brake operating device, characterized in that a seating surface is formed on the operating knob fixed end side of the rod, and one surface of the seating surface is used as a reference surface that comes into contact with the end surface of the operating knob. (2) Utility model registration claim 1, in which a threaded portion is formed on the distal end side of the rod from the seating surface, and the threaded portion is screwed into a screw hole formed in the operating knob, thereby fixing the rod and the operating knob. Parking brake operating device as described. (3) The parking brake operating device according to claim 1 or 2, wherein the urging force of the urging member is applied to a surface of the rod seating surface that is different from the reference surface.
