  "textContent": "An object to provide a brake device for a caster that has a simple structure, provides reliable braking, has no risk of damaging the circumferential surface of a roller, and has high durability. The brake device for a caster includes: a plurality of projecting parts 19 formed concentrically at regular intervals on opposite side-surfaces of a roller 7 in a direction in parallel with the axis, and levers 16 set across the roller at both side-panels 5b of a fork 5 so as to be opposed to the projecting parts, and a claw formed at a tip of each of the levers so as to be opposed to the projecting parts, wherein the levers are operated so that the claw is engaged with a concave part 19b formed between the projecting parts, thereby locking rotation of the roller.",
