A brake for a buggy vehicle includes a plurality of rotatable friction brake plates which are axially slidably and relatively non-rotatably coupled to the input shaft of a reduction device spline-coupled to a propelling shaft, a plurality of stationary friction brake plates alternately superposed with the rotatable friction brake plates, a brake non-rotatable housing which houses the group of the rotatable and stationary friction brake plates therein and which supports said stationary friction brake plates for axially sliding movement and against rotation, a pressure-receiving portion provided in the brake housing to carry one side of the group of the rotatable and stationary friction brake plates, and an operating device capable of urging the other side of the group of the rotatable and stationary friction brake plates against the pressure receiving portion.
