Abstract
A case includes a main case body and an exterior member. The exterior member is welded to the main case body with laser light. The laser light is irradiated onto an irradiation surface. A welding part of the main case body and the exterior member is formed on the inner periphery surface extending along a height direction of the case and is formed such that the irradiation surface is perpendicular to the incident laser light.
Claims20
A method for manufacturing a case comprising:
- a first step of placing an exterior member on an upper side of a main case body;
- and
- a second step of welding a welding part of the main case body and the exterior member from a rear side of the main case body with laser light such that the main case body and the exterior member adhere to each other, wherein
- an irradiation surface of the welding part to be irradiated with the laser light is perpendicular to the laser light that is incident on the irradiation surface, or
- the irradiation surface of the welding part is an almost vertical surface extending along a height direction of a column shape of the case that includes the main case body and the exterior member, the laser light is irradiated obliquely at a predetermined incidence angle with respect to the irradiation surface, and a reflected-light receiving part is formed at a position on which a reflected light from the irradiation surface arrives.
