Claims

[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 is applied via the transmission member; a second engaging portion on which the pushing force of the operation knob is applied via the transmission member; a curved guide portion located between the second engaging portions and having a predetermined radius of curvature with respect to the rotation center of the claw member; A parking brake operating device characterized by being arranged parallel to the axial direction of a knob. (2) Utility model registration claim 1, in which the transmission member contacts the first engaging portion in a point contact state.
Parking brake operating device as described in section. (3) Utility model registration claim 1 or 2, wherein at least one of the first engaging part and the second engaging part is provided with a locking part that restricts upward movement of the transmission member. The parking brake operating device according to item 2. (4) Arm length 1 from the rotational point acting on the first engagement portion to the rotation center of the claw member, and arm length 1 from the rotation center to the engagement point between the sector and the claw member. 2. The parking brake operating device according to claim 1, 2, or 3 of the utility model registration claim, wherein the relationship between 1 and 2 is 1<2.
