Abstract
A rotor includes a laminated core, a plurality of magnets, and a resin portion. The laminated core includes a plurality of outer core portions arranged in a circumferential direction. The plurality of outer core portions and the plurality of magnets are alternately arranged in the circumferential direction. In addition, the outer core portion includes a through-hole that penetrates in an axial direction. The resin portion includes a columnar portion that is disposed inside the through-hole. Accordingly, the rigidity of the resin portion is enhanced. In addition, the resin portion includes a gate mark portion. At least a portion of the gate mark portion is positioned farther radially inward than the through-hole.
