スポンジ砥石の装着装置。It has a boss part in the center that can be removably screwed onto the rotating shaft of the grinder, and a concentric V-shaped ring groove is formed around the boss part, and a tapered cone-shaped groove is formed at the upper end in the ring groove. A fixing attachment/detachment tool in which a plurality of members having head portions are implanted at equal intervals is screwed and fixed to the rotating shaft of the grinder using the boss portion, while a member having a diameter larger than the ring diameter of the ring groove is A disk-shaped hard elastic backing material having a center hole through which the rotating shaft can be inserted is adhered to the back surface of a ring plate-shaped sponge grindstone having a center hole, and the center of the backing material A fitting hole into which the head portion of the pin member can be fitted, corresponding to the pin member, on an imaginary circumference concentric with the material, and a head of the pin member extending continuously in the rotational direction of the rotation axis of the fitting hole. A locking groove is formed in which the pin member can be locked, and after the head portion of the pin member is inserted into the fitting hole of the backing material, the head portion of the pin member is inserted into the locking groove against the elasticity of the backing material. A sponge grindstone mounting device characterized in that the sponge grindstone is mounted on a rotating shaft of a grinder by guiding and rotating the sponge grindstone and locking it.
