A case for storing a grinding wheel which comprises an annular support member and a grinding means provided on the lower end face of the support member. The case includes a first case member and a second case member, the first case member and the second case member are connected to each other by a hinge member in such a manner that they can pivote relative to each other and selectively set to a close state for defining a closed storage space and to an open state for opening the storage space. A receiving means is provided on the first case member and a restricting means is provided on the second case member. The support member is held between the receiving means and the restricting means, and the grinding wheel is stored in the storage space, without allowing the first case member and the second case member to contact with the grinding means.
