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.
Claims21
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 oblique to a height direction of a column shape of the case that includes the main case body and the exterior member and 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 the height direction of the 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.
