From above the upper half 51, pressure is generally applied to the upper half 51 and the lower half by a vibrator with vibration of 20 KHz, that is, the ultrasonic horn 61.
Vibrate in the direction. Then, the vibration by the ultrasonic horn 61 causes the upper half 51, the welding boss 52, and the welding rib 53.
Is transmitted. For this reason, the welding rib 53, which is the tip portion, has the welding surface 5 of the welding boss 55 of the lower half 54.
It collides violently with 6. The heat generated by friction at this time causes the welding rib 53 to melt and weld to the welding surface 56 of the welding boss 55. As a result, the upper half 51 and the lower half 54
And are fused to form a disk cartridge for a magnetic floppy disk.

てしまう。By the way, conventionally, the roughness of the welded surface 56 of the lower half 55 is not particularly specified, and normally, the finishing method at the time of processing when the lower half 55 is formed. According to the roughness. Therefore, the welded surface 56 often has a flat shape without undulations. Then, the area of the surface to be welded 56 that contacts the tip portion of the welding rib 53 becomes large, the vibration energy due to ultrasonic vibration is dispersed, and the energy for welding becomes large.

In some cases, cracks 71 may be generated by being transmitted to a portion having a weak shape.

ことを目的とする。The present invention has been made in view of the above-mentioned circumstances, and ultrasonic waves with low energy are transmitted by efficiently transmitting the vibration energy of the abutting end face of the welded portion to the abutting end face of the welded portion. Welding can be realized, thus preventing the occurrence of cracks, which is of high quality. Also, because the welding time can be shortened, productivity can be improved, and the cost can be reduced by using a pair of upper and lower halves with such a joining structure. Another object of the present invention is to provide a storage case for a high quality information recording medium.

In particular, a welding structure is provided in which the welded surface on the welded boss, which is the abutting portion formed on the lower half, is a rough surface with respect to the welding rib on the welded boss, which is the abutting portion formed on the upper half. There is. Then, in each of the two embodiments, the welding rib is melted by ultrasonic vibration applied from the upper side of the upper half and is welded to the surface to be welded to be integrated. Incidentally, the disk cartridges for the magnetic floppy disks of these two embodiments would normally have a magnetic floppy disk built therein at the time of ultrasonic welding, but here, for convenience of explanation, a magnetic floppy disk is used. Omit it. Further, the upper half side has four welding bosses each having a welding rib formed at its tip portion, and the lower half has four welding ribs having a roughened surface to be welded. However, for the sake of convenience of explanation, the explanation will proceed while considering each one.
