A sheet metal outsert-molded gear, in which a molded resin gear is formed by outsert-molding along the outer perimeter of a disk-shaped sheet metal, including:
- one or more pairs of notches, holes, or protrusions which extend through the disk-shaped sheet metal in a width direction and are provided in the outer perimeter of the disk-shaped sheet metal, and the outer perimeter of the disk-shaped sheet metal extends into the molded resin gear,
- wherein a weld is formed at positions between at least one of the one or more pairs of notches, holes or protrusions in the outer perimeter of the disk-shaped sheet metal and,
- a first spacing between the notches, holes or protrusions of the one or more pairs of notches, holes or protrusions at the weld is less than a second spacing between adjacent pairs of notches, holes or protrusions.
