SCATTERING PLATE, GRINDING WHEEL, AND GRINDING DEVICE

WIPO Patent Application WO/2015/004973

A1

A scattering plate (4) for scattering a supplied solution supplied via a supply tubing is characterized by the following: being provided with a planar member (41) that can be disposed at a position facing an opening end of the supply tubing so that the thickness direction is substantially parallel to a direction (D1) of supply of the supplied solution and so as to rotate about a rotational axis substantially parallel to the thickness direction; being provided, in the planar member (41), with a scattering hole (42) through which the supplied solution is able to pass and which perforates in the thickness direction at a location other than a rotational center (O) of the planar member (41); and a wall surface (421) located on the rear side of a direction (D2) of rotation in the scattering hole (42) being inclined so that a wall surface end section (421A) located rearmost in the direction of rotation on a facing surface (411) side facing the supply tubing (3) is located more in front in the direction (D2) of rotation than a wall surface end section (421B) located rearmost in the direction of rotation on a non-facing surface (412) side.
