摘要： A magnet roller includes a roller-shaped body constructed of a magnetic field generating material, a first support rod provided to a first axial end of the body; and a second support rod provided to a second axial end of the body. At least one of the first and second support rods is constructed of a nonmagnetic material and includes a projecting part projecting outside the body from an end face of the body and a buried part united to the projecting part and positioned inside the body. The buried part includes a reduced-area portion smaller than a base end of the projecting part adjacent to the buried part in cross-sectional area perpendicular to an axial direction of the first and second support rods.

摘要： A roller includes a cylindrical body having openings on both ends thereof and a press-fit member fitted in at least one of the openings of the cylindrical body with an outer circumferential face thereof in contact with an inner face of the cylindrical body. The outer circumferential face of the press-fit member is grooved obliquely to an axis of the cylindrical body, and the inner face of the cylindrical body is smooth at least in a portion that contacts the outer circumferential face of the press-fit member.
