としたものである。However, the above-mentioned tapping connection or welding connection fixing method requires the equipment of a welding machine such as a screw, a tapping machine, or an ultrasonic horn, and many troubles occur during the assembly process. There is a problem that the process is complicated and the cost is greatly affected, and the appearance quality is also adversely affected. In the case of a type with a fitting, for example
Although there is Japanese Patent Publication No. 69877, in this example, as shown in FIG. 5, the upper and lower cases are assembled even if the engaging protrusion a having a hook or head provided on the case is fitted into the engaging recess b and locked. Is complicated, or even if a convex part that shrinks the head when penetrating the hole for locking is used to make it easy to hammer in and expand the engagement, it is difficult to clamp and the maintenance of the united state is unstable. It was not completely satisfactory in terms of reliability, as it was disengaged or loosened due to a drop impact or the like, and a gap was created at the joint between the upper and lower cases. The present invention is intended to eliminate these conventional drawbacks, simplifies the manufacturing process and the combination processing process without using a tapping or welding process for joining the upper and lower cases, and eliminates rattling and detachment after the case is assembled, and The purpose is to improve the appearance quality at a cost.
