A brush assembly of a cleaner includes a driving motor mounted at a cleaner main body, for generating a rotary force; a brush rotatably disposed at a suction opening formed at the cleaner main body; and a driving force transfer device installed between the driving motor and the brush, rotating the brush by transferring a rotary force of the driving motor to the brush, and protecting the driving motor by preventing transfer of a load generated at the brush to the driving motor. Accordingly, the driving motor can be continuously rotated even if the brush cannot be rotated by being caught by a stuff or the like, thereby preventing motor damage.
