砥石。[Scope of Claim for Utility Model Registration] (1) A base metal formed by integrally molding a protrusion around the outer periphery or outer edge of an annular hub portion, and a grinding wheel. A grinding wheel comprising grains and a grinding layer formed at the tip of a protrusion of the base metal, wherein the base metal is covered with an annular plate-shaped sound deadening member provided coaxially with the hub part. A grinding wheel characterized in that the sound deadening member is sandwiched between the base metal and an annular plate-shaped clamping member that covers the exposed surface of the sound deadening member. (2) The acoustic impedance of the material constituting the sound deadening member is 1/3 of the acoustic impedance of the respective materials constituting the base metal and the sandwiching member.
The grinding wheel according to claim 1, characterized in that:
