PURPOSE:To certainly and easily move a brush, to simplify a structure and to well clean a cylindrical inner surface having a polygonal cross section or unevenness by mounting a vibration member, the brush implanted in the outer periphery of the vibration member and a vibrator applying vibration to the vibration member. CONSTITUTION:A vibration member 1 having a brush 2 and a vibrator 3 are integrated to be inserted in a cylindrical inner surface 5 to be cleaned and, when the driving force from an external drive source 7 is transmitted to the vibrator 3 through a connector 6, the vibrator 3 is driven to vibrate the vibration member 1 and the brush 2 integrated with the vibration member 1 is also vibrated. When the connector 6 is pushed or pulled in this state and the brush 2 is moved in the axial direction of the cylindrical inner surface 5, the brush 2 rubs the cylindrical inner surface 5 under vibration to clean the same. That is, the brush 2 properly having elastical reaction force receives the intensive vibration of the vibrator 3 to elastically collide with the cylindrical inner surface 5 and the minute rubbing action accompanied by this collision is performed at a high cycle to clean the cylindrical inner surface. |
