Document Type and Number:

WIPO Patent Application WO/2013/061540

Kind Code:

A1

Abstract:

[Problem] To provide a grinding tool with the eccentric rotation shaft of the grinding disc rotatably installed at a position that is shifted from the center line of the drive shaft of the drive motor, wherein: the rotation rate of the grinding disc is limited to a stable range of rotation rates, preventing extreme elevation in the rotation rate even when not grinding and no load is applied and preventing extreme reduction in the rotation rate even when load is applied during grinding; the workpiece is ground efficiently; and the tool does not generate marks or patterns on the ground surface. [Solution] This grinding tool with the eccentric rotation shaft of the grinding disc with attached grinding material installed via a bearing at a position that is shifted from the central drive shaft line of a rotating disc fixed on a drive shaft that is connected to a motor, is characterized in comprising a clutch in which a grinding disc-side clutch component member installed on the grinding disc or on the eccentric rotation shaft that is fixed to the grinding disc and a rotating disc-side clutch component member installed on the rotating disc are linked via a sliding surface capable of sliding and of transmitting the drive force.
