<p>PROBLEM TO BE SOLVED: To provide a joint structure of resin-made parts which are formed before welding by injection molding with an identical thickness, normally using the same material and can be easily joined together, even when the parts are easily deformed by an adverse effect of an inverted blister and a warpage is generated on the joint faces 22a and 23a which are easily subjected to it after molding. SOLUTION: In the joint structure, of the resin-made parts 22 and 23, which join the joint faces 22a and 23a formed on a plurality of the resin-made parts 22 and 23 respectively by superposing the parts, the rigidity of each of the parts in an orthogonal direction with the joint faces 22a and 23a is increased in one part 23 and decreased in the other part 22. The difference of the rigidity can be imparted by differentiating the thicknesses A and B of the parts or reinforcing ribs or the material or the shape.</p> |
