<p>For a hand-held grinder, conventionally, no particular restriction has been made in the case of adjusting a position of a grinding stone cover, which covers a side of a grinding stone for preventing dust from scattering, and therefore, in some cases, a dust scattering prevention function is impaired if the grinding stone cover is excessively rotated about a spindle axis.. The present invention prevents the excessive rotation in the case of adjusting a position of the grinding stone cover, so that the dust scattering prevention function can be reliably performed.
It is configured to provide a stopper projection (27) to a grinding stone cover (20) and provide a stopper abutting portion (8e) on a side of a gear housing (8) in order to restrict a position adjustable range through abutment of the stopper projection (27) to the stopper abutting portion (8e) in a position where the grinding stone cover (20) has rotated in a rotational direction of the grinding stone by about 60 degrees.</p> |
