Abstract
A rotor is provided with a rotor core, a magnet inserted into the rotor core and a filling portion arranged in a space between the rotor core and the magnet. The space between the rotor core and a radially outer side surface of the magnet has a uniform width in a central portion (portion (A)) with respect to a width direction (of arrow (DR)) of the magnet. A width of the space in an end portion (portion (B)) with respect to the width direction (of arrow (DR)) of the magnet is larger than that of the space in the portion (A).
