    摘要: Rigidity is improved at a part where side frame pieces overlap each other in a side frame. In a vehicle seat provided with a seat back frame, a side frame of the seat back frame has a first side frame piece and a second side frame piece partially overlapping each other in a direction of extension of the side frame. The side frame has an overlapping part where both the first side frame piece and the second side frame piece overlap each other. At the overlapping part, the side frame pieces overlap each other in a state where a plurality of closed regions and closed by being surrounded by both side frame pieces are formed in a cross section of the overlapping part intersecting with the direction of extension of the side frame.

    摘要: A first through-hole is formed on a target side wall in a specific pipe of a structure, and a second through-hole is formed on an opposing side wall which opposes the target side wall. A manufacturing method of the structure includes arranging a specific member along an outer surface of the target side wall. The manufacturing method further includes radiating laser light of a laser welder onto a first bonding region via the second through-hole on the opposing side wall, to weld the specific pipe and the specific member in the first bonding region. The first bonding region includes a boundary between an edge portion of the first through-hole on the target side wall and the specific member.

    摘要: A laser welding method for irradiating a plurality of stacked metal plates in an upright position with a laser beam to weld the plurality of stacked metal plates is provided. The laser welding method includes irradiating the plurality of metal plates with the laser beam to form a circular molten pool and scanning the laser beam once around an outer periphery of the molten pool to enlarge the molten pool. In the enlarging of the molten pool, a scanning start point of the laser beam is set within a range from 135 degrees to 315 degrees in a scanning direction of the laser beam, with 0 degrees directly above the molten pool in a vertical direction.
