ABSTRACT:
The present invention provides an assembling method facilitating building-in work of a door and tensile coil spring in a cartridge case. In an assembling of a magnetic tape cartridge, hold the door and coil spring with a component holding jig, grip a part of the door with a robot hand of an assembling apparatus, engage the other end of the coil spring in a spring engaging portion, elongate the coil spring with moving the spring engaging portion in a closing direction, make a state in which the coil spring can be attached to the case-side spring hooking portion as it is when fitting the door in a closing position of the guide groove, then fit in the door, and attach the other end of the coil spring to the case-side spring hooking portion, thereby being able to simultaneously build the door and coil spring in a lower half.
