To provide a parking brake operation release assist device which can easily and safely release an operation state of a parking brake in a short period of time and which enables a diaphragm to be safely replaced in a short period of time.SOLUTION: A parking brake operation release assist device is used for a wheel park device for actuating a wheel cylinder of a drum brake by an operating physical force in the direction of drawing an operation rod of a spring chamber. A base end of the assist device has a mounting nut that is screwed to a mounting bolt passing through a hole part of a bracket, and a stopper member that is latched to a coupling member larger in diameter than the operation rod so as to regulate movement in the direction of drawing the operation rod.SELECTED DRAWING: Figure 1
