Irregular wear occurs according to use, irregular wear occurs, and vibration phenomenon occurs in the rotating grinding stone. The vibrating grinding stone causes difficulty in grinding and reduces the life of the grinding wheel. Thus, according to the present invention, the resilient contact device of the driven grindstone, which is resiliently mounted by a spring, has a high linearity toward the rotating grindstone while pushing the driven grindstone so that the rotation axis of the driven grindstone becomes parallel to the rotation axis of the rotating grindstone, . |
