Abstract
A magnet holder is used in a rotational angle sensing device and is shaped in a tubular form while the magnet holder is configured to hold a magnet opposed to a magnetic sensor and is also configured to be securely press-fitted to a rotatable body. The magnet holder includes: a magnet holding portion that is located at one side of the magnet holder in an axial direction; a press-fitting fixation portion that is located at another side of the magnet holder in the axial direction; and a connecting portion that connects between the magnet holding portion and the press-fitting fixation portion. An outer diameter of the press-fitting fixation portion is different from an outer diameter of the magnet holding portion, and a wall thickness of the press-fitting fixation portion is different from a wall thickness of the magnet holding portion.
