Application Number: JP,2024-192958
Category (FI): B23K26/21@N,B23K26/24,H01S5/02208
Stage: PROBLEM TO BE SOLVED: To provide a housing of an optical device which is new and improved so that a problem caused by laser welding further hardly occurs when manufacturing the housing of an optical device by, for example, laser-welding a plurality of members, and provide the optical device, a laser welder and a laser welding method.SOLUTION: A housing of an optical device comprises: a plate-shaped first member having a first outer surface and a first end edge; a plate-shaped second member having a second outer surface and a second end edge extending along the first end edge; and a linear weld part which is obtained by welding a portion between the first outer surface and the second outer surface out of a boundary portion between the first end edge and the second end edge. The weld part extends from a clearance between the first outer surface and the second outer surface in a second direction intersecting with a first direction along the first outer surface and the first end edge, and the boundary portion includes an opposing zone which extends in a third direction intersecting with the first direction and the second direction as an opposing zone in which the first end edge and the second end edge face each other with an interval between the weld part and an accommodation chamber or contact with each other.SELECTED DRAWING: Figure 2 (Grant)
