摘要 |
In the reel of a magnetic tape cartridge, in which the reel with magnetic tape wound thereon is rotatably housed in a cartridge case, a magnetic metal plate is molded integrally on a reel bottom surface by insert molding. The metal plate is formed into an annular shape having a central hole. In a reel bottom wall closing the central hole of the metal plate with resin injected from a gate at the center of the central hole of the metal plate when the insert molding is performed, a recess is formed between a gate trace at the center portion of the bottom wall and an inner peripheral surface of the central hole of the metal plate. <IMAGE> |
