A cutter device includes a fixing holder, a spherical cylinder, and a cutter holder. The fixing holder has a through hole, and a spherical outer circumferential surface in which a key groove is formed. The spherical cylinder includes a through hole that has a spherical inner circumferential surface in which a key groove having a spherical bottom surface is formed, and a spherical outer circumferential surface having a key groove formed at a position shifted around a rotational axis with respect to the key groove. The cutter holder includes a through hole that has a spherical inner circumferential surface in which a through hole having a spherical bottom surface is formed, and a cutter blade. These components are rotationally slidably connected by keys.
