４のたわむ分だけ同じように当るので一定の大きさの面
取り作業を行なうことがそれだけ容易になるという効果
を奏する。When the grinding tool is formed as described above, (a) the tool is formed by arranging a plurality of linear spring bodies 3 in parallel, and has a grinding property, so that the workpiece is Even if the processed part has a complicated shape, the shape ←) Since the spring body 3 is strongly restrained by the fixed part 4 such as the part near the boxwood root, the fixed part 4
However, in the case of the conventional type in which the fixing part 4 is not made of an elastic body, the way it hits the edge W of the workpiece is different between the part near the root and the part far from the boxwood root, but if the fixing part 4 is made of an elastic body, the bending of the fixing part 4 will be different. The effect is that it is easier to perform chamfering work of a certain size because the chamfers are applied in the same way.

（ハ）並列された各線条ばね体３は、その材料かられか
