ABSTRACT:
A door member for a tape cartridge capable of automating the operation of mounting a spring member thereon. A door body is in the form of a flat plate. A spring-mounting portion is in the form of a flat plate and extends from the door body and has one end face in which opens an insertion hole formed therein for having a foremost end of a spring member inserted therein. One surface-side wall and another surface-side wall define the insertion hole from an opening-side region of the insertion hole toward the end face to an innermost region of the insertion hole. Cutouts are alternately formed in the one surface-side wall and the other surface-side wall, such that the cutouts communicate with the insertion hole. A protuberance is formed on an inner surface of the one surface-side wall facing the innermost region, for engagement with the foremost end of the spring member.
