PURPOSE:To automate assembling of a spring by providing a tentative lock part locking tentatively an end of a spring locked by a shutter to a spring storage part of a case to perform the assembling of the spring as the combination of simple operations. CONSTITUTION:A linear is stuck to upper and lower shells 4, 5, the spring 3 is fitted and the edge of the spring 3 is fitted tentatively to a lock groove 8 and a tentative lock part 10. Then the upper shell 4 and the lower shell 5 are overlapped while clipping a disc, they are welded to form the case 1 and the shutter 2 is fitted. Then the shutter 2 is moved to the spring 3 fitted tentatively and the end of the spring 3 is locked to a locking claw 9 of the shutter 2. In this state, the end of the spring 3 latched to the locking claw 9 is pushed down to the lower shell 5 to override the tentative locking part 10 and the shutter 3 is detached, then one end of the spring 3 is locked to the locking claw 9 of the shutter 2, the shutter 2 is moved in a direction to close the heat slot 6 of the case 1 by the energyzing force of the spring 3 to complete the assembling of the cartridge.
