項記載のパーキングブレーキ操作装置。[Claims for Utility Model Registration] (1) An operating lever for operating a parking brake; a fixed sector rotatably supporting the operating lever and having engaging 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 the grip portion of the operating lever; and movement of the operating knob moves the claw member into and out of the engaged position. a transmission member that rotationally displaces the operating knob to the mating position; and a biasing member that biases the claw member to be constantly engaged by protruding and biasing the operating knob, the claw member being the biasing member. a first engaging portion on which the engagement biasing force of acts through the transmitting member; and a second engaging portion on which the pushing force of the operation knob acts through the transmitting member; A parking brake operating device characterized in that a locking portion for restricting upward displacement of the transmission member is provided in the engaging portion, and a position of a rotation point is defined. (2) The parking brake operating device according to claim 1, wherein the locking portion is formed by curving the tip of the second engaging portion. (3) The arm length l1 from the rotational point acting on the first engaging portion to the rotation center of the claw member, and the arm length from the rotation center to the engagement point between the sector and the claw member. Paragraph 1 or 2 of the scope of utility model registration claims in which the relationship with l 2 is such that l 1 < l 2
