Abstract
A vehicle rotating electrical machine includes a pulley unit and a cap that covers an opening portion of the pulley unit. The pulley unit includes a pulley shaft that has a hollow cylindrical shape and is mechanically connected to a rotation shaft. On an inner peripheral surface of the pulley shaft, a polygonally-shaped hole portion, a first and a second circular hole portions, and an inner diameter thread portion are formed. The cap includes a planar section and a plurality of pillar sections. The planar section covers the opening portion. The pillar sections extend from the planar section to the inner diameter thread portion, and include a bulge portion that bulges outward in a radial direction of the pulley shaft. The bulge portion is located at a position corresponding to the second circular hole portion in a state where the opening portion is covered by the planar section.
