PROBLEM TO BE SOLVED: To provide a braking device of a track traveling type machine capable of controlling a braking force and alleviating the load on a track traveling type machine by suppressing sudden braking.SOLUTION: A braking device of a track traveling type machine includes an acceleration meter 31 measuring acceleration A at stopping of the track traveling type machine, a branch line 32 branched from the middle of a cap side line 17 as a supply passage of a working fluid of a fluid pressure unit 14 for pressing a brake pad 12 against a rail 4 by extending a fluid pressure cylinder 13 and communicating with a tank 15, a pressure-reducing valve 33 having a proportion electromagnetic relief provided in the middle of the branch line 32 and a controller 34 outputting a signal S, which increases a releasing quantity of the working fluid to the branch line 32 in proportion to the amount of the acceleration A measured by the acceleration meter 31 to the pressure-reducing valve 33 having the proportion electromagnetic relief.SELECTED DRAWING: Figure 2
