1. A brush apparatus, comprising:
- a rotatable brush member;
a driving unit that rotates the brush member; and
a blocking unit disposed between the brush member and the driving unit configured to selectively block a driving force transmitted between the brush member and the driving unit,wherein the driving unit comprises;
a suction motor to generate a suction force; and
a single continuous connecting belt connecting the suction motor and the blocking unit,wherein the blocking unit comprises;
a power transmitting part to transmit the driving force transmitted from the single connecting belt to the brush member; and
a blocking part to selectively block the driving force transmitted between the brush member and the power transmitting part,wherein the power transmitting part comprises;
a first connecting member coupled with the connecting belt;
a second connecting member coupled with the first connecting member; and
a third connecting member disposed on the brush member to be selectively coupled with the second connecting member by the blocking part so as to drive the brush member, andwherein the second connecting member comprises a bearing rotatable by friction contact with the first connecting member.

Abstract
A brush apparatus capable of controlling a drive of a brush member with a simplified structure and a vacuum cleaner having the same. The vacuum cleaner includes a rotatable brush member, a driving unit to drive the brush member, and a blocking unit disposed between the brush member and the driving unit to selectively block a driving force transmitted between the brush member and the driving unit. The driving unit includes a suction motor to generate a suction force, and a single continuous connecting belt connecting the suction motor and the blocking unit.

10. A vacuum cleaner, comprising:
-
a cleaner body in which a suction force is produced by a suction motor; a rotatable brush member for separating dust or dirt from a surface to be cleaned while receiving a driving force from the suction motor; a blocking unit disposed between the brush member and the suction motor to selectively block the driving force transmitted between the brush member and the suction motor; and a single continuous connecting belt connecting the suction motor and the blocking unit, wherein the blocking unit comprises; a power transmitting part to transmit the driving force transmitted from the connecting belt to the brush member; and a blocking part to selectively block the driving force transmitted between the brush member and the power transmitting part, wherein the power transmitting part comprises; a first connecting member coupled with the connecting belt; a second connecting member coupled with the first connecting member; and a third connecting member disposed on the brush member to be selectively coupled with the second connecting member by the blocking part so as to drive the brush member, and wherein the second connecting member comprises a bearing rotatable by friction contact with the first connecting member. - View Dependent Claims (11, 12, 13, 14, 15, 16)
