Zusammenfassung:	To provide an abrasive wheel capable of preventing a grindstone from coming off an abrasive wheel during grinding processing or being broken without coming off.SOLUTION: An abrasive wheel includes: an annular base that has a free end surface and a surface for being mounted on a wheel mount; an annular groove that is annularly formed on the free end surface of the annular base; and a plurality of grindstones that are fixed to the annular groove with an adhesive infilled into the annular groove. The annular groove is defined by a pair of side walls and a top surface. The side wall assumes a shape that spreads out like an unfolded fan toward the top surface from the free end surface.SELECTED DRAWING: Figure 3 【課題】研削加工中に研削ホイールから砥石が脱落したり、或いは脱落せずに破損したりすることを防止できる研削ホイールを提供することである。【解決手段】自由端面とホイールマウントへの装着面とを有する環状基台と、該環状基台の該自由端面に環状に形成された環状溝と、該環状溝内に充填された接着剤によって該環状溝に固着された複数の砥石とを含む研削ホイールであって、該環状溝は一対の側壁と頂面とにより画成され、該側壁は、該自由端面から該頂面に向かって末広がり形状をしている。【選択図】図３
