<P>PROBLEM TO BE SOLVED: To solve a problem that welding is afraid to be incomplete in a case of making a water proof case in which the inside is sealed as water proof jointing both of the circumferences over whole circumference in a state of an upper cover and a lower cover being put together on each fringe, a flange shaped rib is, formed all over the whole circumference of both covers, at the same time an adhesion domain where an adhesive is applied and a welding domain where is welded by a laser light both of which are formed as double rings of the inside and the out side, the adhesive on an adhered range is swollen into the welded region, so the rib is not completely molten even if a laser light is irradiated as the result, welding is resulted to be incompleteness. <P>SOLUTION: A adhesive pool 6 for preventing the adhesive from invading to the welding region from the adhesion region is made between the adhesive region and the welding region. <P>COPYRIGHT: (C)2009,JPO&INPIT |
