To provide a grinding device in which a grinding wheel can be easily attached to a wheel mount.SOLUTION: A grinding unit has a spindle and a wheel mount 34 comprising a first base whose upper surface side is fixed to a tip part of the spindle. To the wheel mount is attached a grinding wheel 36 comprising an annular second base whose upper surface side is attached to a lower surface side of the first base and a grinding stone 44 arranged on the lower surface side of the second base. The second base has an inner peripheral surface 40e defining an opening 40d penetrating from the upper surface through the lower surface of the second base. The wheel mount has a plurality of first chuck claws 62 fixed to the lower surface side of the first base to contact the inner peripheral surface of the second base and a second chuck claw 66 attached to the lower surface side of the first base to contact the inner peripheral surface of the second base. The second chuck claw is connected to a support member 72 fixed to a center side of the first base through an energizing member 74, and is supported to be movable in a radial direction of the first base by expansion and contraction of the energizing member.SELECTED DRAWING: Figure 4 【課題】研削ホイールをホイールマウントに容易に装着可能な研削装置を提供する。【解決手段】研削ユニットは、スピンドルと、上面側がスピンドルの先端部に固定される第１基台を備えたホイールマウント３４と、を有し、ホイールマウントには、上面側が第１基台の下面側に装着される環状の第２基台と、第２基台の下面側に配設された研削砥石４４と、を備えた研削ホイール３６が装着され、第２基台は、第２基台を上面から下面まで貫通する開口４０ｄを画定する内周面４０ｅを有し、ホイールマウントは、第１基台の下面側に固定され第２基台の内周面に接触する複数の第１チャック爪６２と、第１基台の下面側に装着され第２基台の内周面に接触する第２チャック爪６６と、を有し、第２チャック爪は、第１基台の中心側に固定された支持部材７２に対して付勢部材７４を介して連結され、付勢部材の伸縮によって第１基台の半径方向に移動可能に支持されている。【選択図】図４
