    摘要: A magnet rotor in which rotation prevention and positional displacement (rattling, and misalignment of axes) between a magnet and a rotor body can be restricted, a movable magnet type-instrument with the magnet rotor, and a stepping motor with the magnet rotor. In the magnet rotor, projections (11) and recesses (12) arranged with predetermined intervals and formed in a substantially rectangular shape are provided on the inner wall of a hollow section of an annular magnet (10). Rising side wall sections (11A) defined by the projections (11) are radially directed with the position of the axis (G) of the magnet rotor (R) as the standard. In the rotor body (20), rotation prevention sections (21) for preventing relative rotation between the rotor body (20) and the annular magnet (10) are formed by placing a plastic material along the shapes of the projections (11) and the recesses (12).
