Dust cover for grinder and a grinder including the dust cover

摘要

A dust collecting cover for a grinder and the grinder including the dust collecting cover are provided to enable a cover unit to slide toward a rotation shaft direction about a dust collecting main body, thereby effectively grinding a corner part of a bottom to be grinded. A dust collecting cover for a grinder includes a housing having a cylindrical side wall(31) and a ceiling(32). A direction of the housing facing the bottom is opened. The ceiling is crossed with the cylindrical side wall. The housing includes a gate unit and a cover unit(34). A part of the side wall is cut to a gate part. The cover unit is installed at the gate part. The cover unit slides about the main body in a radial direction of a rotary shaft. The cover unit has an elastic restoring force.
