A brake device for an elevator hoisting machine includes: a rod movable in an axial direction; a plurality of pistons provided to the rod so as to be arranged side by side in the axial direction; a cylinder configured to accommodate each of the pistons therein and including a pressure control chamber formed between the cylinder and each of the pistons; a lining provided to the rod so as to be capable of coming into contact with a contacted body; and a spring device configured to press the pistons in a direction in which the lining is pressed against the contacted body. Gaps are respectively formed between at least one of the plurality of pistons and the rod and between pistons adjacent to each other. Each of the pistons is configured to be driven by a change in air pressure in the pressure control chamber.
