Abstract
A metal plate of a recording tape cartridge is provided with a tapered portion at an outer circumference thereof. In a state in which the metal plate is attached at a fixed-side mold plate of a metal mold for molding a reel hub and a lower flange, a gap is formed between the tapered portion and the fixed-side mold plate. During molding, molding material flows into the gap. Because of this gap, an annular pawl portion is formed at the reel hub, which annular pawl portion integrally joins the metal plate with the reel hub by sandwiching the metal plate via the tapered portion.
