The present invention pertains to a parking brake device of a construction vehicle and a forklift. More specifically, the parking brake device is mounted to an axle input shaft, which is connected to a transmission, in a simple structure using a reduction gear such that the parking brake may readily be carried out using a small force according to a reduction ratio. That is, in the present invention, a parking reduction gear set is mounted between a pair of thrust bearings, which are mounted to the outer diameter portion of an axle input shaft, such that the parking reduction gear set carries out functions as a spacer for each of the thrust bearings and simultaneously carries out a parking brake function; a hydraulic (automatic) or mechanical (manual) brake operation member is connected to the parking reduction gear so that the length of the axle input shaft may be reduced and simultaneously the parking brake device may be implemented in a simpler structure; and parking brake performance may readily be carried out using a small force according to a reduction ratio. |
