用パーキングブレーキ装置。 A parking brake device that stops the rotation of the wheel by pressing a roller installed approximately perpendicular to the wheel's rotational direction against the outer diameter of the wheel, and a roller attached to the vehicle body outside the wheel's outer diameter that is approximately perpendicular to the wheel's rotational direction. A deformable lever 2 is pivoted at right angles to the axis of the deformable lever 2, and a roller 4 is pivoted to the protruding portion b of the deformable lever approximately at right angles to the rotating direction of the wheel. It can be so. The mounting position of the roller 4 is such that the longest distance L between the pivot center line of the deformable lever 2 and the outer diameter of the roller 4 is longer than the shortest distance M between the outer diameter of the wheel and the pivot center line of the deformable lever 2. , the trajectory of the arc drawn by the tip of the roller 4 becomes a wedge angle at the point of contact with the outer diameter of the wheel, and the roller 4 is rolled on the wheel, and then rolled while holding down the top of the wheel, to cover the shortest distance M. A parking brake device for a vehicle in which a stopper is provided by providing another protruding portion (c) so that the wheel stops on the passing wheel, thereby limiting the range of arc movement.
