PROBLEM TO BE SOLVED: To provide a manufacturing method of a product with a hollow section, which excels in speed of joining operation to bond a lid member to a product body. SOLUTION: The lid member 6 is placed on a stepped section 7 of groove of the product body 2. A top flat face of a rotary tool 8 is abutted and moved so as to cover both sides of rim 6a, 6b of the lid member 6 and the lid member 6 is joined to the product body 2. Both sides of rim 6a, 6b of the lid member 6 are concurrently joined so that the speed of joining work is excellent. COPYRIGHT: (C)2007,JPO&INPIT
