FIG. 1 is a partially cutaway view showing the main parts of a foot-operated parking brake device to which the present invention is applied. FIG. 2 is an enlarged view of the main part of the device shown in FIG. 1, and is a view showing the rotating state of the pawl when the parking brake pedal is depressed. Figures 3 and 4 show changes in the amount of extension of the tension coil spring and the biasing force F until the engagement pawl of the pawl overcomes the engagement teeth when the parking brake pedal of the parking brake device shown in Figure 1 is depressed.

式パーキングブレーキ装置。[Claims for Utility Model Registration] A parking brake pedal that includes a pedal bracket, and a parking brake pedal that is rotatably provided on the pedal bracket and is rotatable about one axis, and that has a plurality of engagement teeth formed along an arc centered on the one axis. and has an engaging pawl at one end and is rotatable about an axis parallel to the one axis in the middle part, and the parking brake is adjusted based on the engagement between the engaging pawl and the engaging teeth. a pawl that prevents the pedal from rotating back from the depressed position; and a pawl that is stretched between the other end of the pawl and the pedal bracket, and that engages the pawl with its engaging claw and the engaging tooth. and a tension coil spring that is constantly biased in the direction of movement, and when the parking brake pedal is depressed, the pawl engages in the engagement while repeatedly rotating back and forth at a small angle against or in response to the biasing force of the tension coil spring. In a foot-operated parking brake device in which a pawl rides over the engagement teeth, the other end of the pawl is attached to one end of the tension coil spring when the pawl is located at a rotation end position where it engages with the engagement teeth. The other end of the tension coil spring is attached to the pedal bracket so that the tension coil spring is substantially parallel to a straight line passing through the center of rotation of the pawl. type parking brake device.
