Claim 9:
10. A method for manufacturing a rotor that rotates by receiving a magnetic field of a stator, comprising:
a step of arranging a plurality of permanent magnets on an outer peripheral part of a rotor core and arranging a load reception block on an end surface of the rotor core in a rotation axis direction;
a step of arranging a substantially tubular magnet cover on exterior of the rotor core, the plurality of the permanent magnets, and the load reception block; and
a step of caulking an end edge of the magnet cover in the rotation axis direction radially inward and bringing the caulking part of the magnet cover into contact with an end surface of the load reception block,
wherein at least the end on one side of the permanent magnet in the direction along the rotation axis protrudes outward from the end of the rotor core on the same side in the direction along the rotation axis,
an abutting part of the load reception block with the flange part is arranged at a position more outside than the end of the permanent magnet in the direction along the rotation axis,
the rotor core has
a substantially cylindrical core main body part, and
a plurality of salient poles protruding in a radial direction from an outer peripheral surface of the core main body part;
the plurality of the permanent magnets are disposed between the plurality of adjacent salient poles and abut against the salient poles; and
the load reception block has:
an annular part that is arranged to overlap an end surface of the core main body part in the direction along the rotation axis, and
a plurality of legs that are arranged to protrude in the radial direction from an outer peripheral surface of the annular part and overlap an end surface of each of the salient poles in the direction along the rotation axis.
