1. A rotor, comprising:
a rotor core that comprises a plurality of steel sheets laminated along an axial direction of a rotation axis of the rotor;
a plurality of permanent magnets arranged on an outer peripheral part of the rotor core;
a substantially tubular magnet cover that covers an exterior of the rotor core and the plurality of permanent magnets in a radial direction; and
a pair of load reception blocks that are arranged on both end surfaces of the rotor core in the axial direction respectively, wherein
the rotor core has
a substantially cylindrical core main body part, and
a plurality of salient poles protruding in the radial direction from an outer peripheral surface of the core main body part;
the plurality of permanent magnets are disposed between the plurality of adjacent salient poles;
the magnet cover has:
a peripheral wall that covers the exterior of the rotor core and the plurality of permanent magnets in the radial direction, and
a pair of flange parts which are bent radially inward and arranged on both ends of the peripheral wall in the axial direction respectively; and
each of the load reception blocks has:
an annular part that abuts against an end surface of the core main body part in the axial direction, and
a plurality of legs that protrude in the radial direction from an outer peripheral surface of the annular part and abut against an end surface of each of the salient poles in the axial direction,
each of the load reception blocks is held between the corresponding one of the flange parts and the rotor core in the axial direction, and
the plurality of salient poles are held between the plurality of legs in the axial direction,
wherein the steel sheets adjacent in the axial direction are embedded with each other in a concave-convex manner at portions other than the plurality of salient poles.
