1. A magnet holder that 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 comprising:
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, wherein:
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; and
each of an outer surface and an inner surface of the connecting portion is a tapered surface that is formed to extend circumferentially all around a rotation axis of the rotatable body.
