Since the working hole is formed by notching and opening one side of the brake lever main body, the rigidity of the region of the brake lever main body where the notch is opened may significantly decrease locally.

For this reason, it is necessary to take countermeasures such as increasing the thickness of the brake lever main body or expanding and enlarging the periphery of the work hole to secure rigidity, but the brake lever main body is large and lightweight. It causes problems such as going backwards.

Therefore, an object of the present invention is to provide a parking brake device for a vehicle in which the pulling stock adjustment work of the brake lever main body can be performed without any trouble without increasing the thickness and the rigidity can be secured.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, a pivot shaft is provided as a center on one side of a brake lever body having an inverted U-shaped cross-section that is pivotally supported by a base plate. An arc-shaped cable guide portion and a tool insertion concave portion that is continuous with the cable guide portion and is formed by cutting out one side of the brake lever body to be pulled out in the vertical direction are provided, and the brake cable arranged along the cable guide portion. The adjustment bolt is coupled to the end of the, the adjustment bolt is screwed into a nut provided in the base of the tool insertion recess, the opening of the tool insertion recess along the inner wall surface of the recess in the tool insertion recess area. A reinforcing member is arranged and fixed so as to traverse.

[Operation] In such a parking brake device, traction control of the brake cable can be performed by operating the brake lever main body. Next, if the tool is inserted using the tool insertion recess and the nut is rotated, the pulling allowance of the brake lever can be adjusted. In this case, since the reinforcing member is arranged and fixed along the inner wall surface of the recess, there is no hindrance to the work during adjustment.
