Abstract
A manufacturing method of a housing that includes a first case having a first surface, a second case having a second surface opposite to the first surface, and ribs provided between the first case and the second case includes disposing the ribs on the first surface, and joining the first case and the second case together by melting the ribs. In the disposing, in a case where a load in a first direction orthogonal to an applied surface including a joined surface between the first case and the second case is applied to the applied surface, a volume of each rib is set so that maximum values of stresses generated in a plurality of regions having the same area of the ribs fall within in a range from a value of 80% of a yield stress value of a material of the ribs to the yield stress value.

A manufacturing method of a housing that includes a first case having a first surface, a second case having a second surface opposite to the first surface, and ribs provided between the first case and the second case, the manufacturing method comprising the steps of:
- disposing the ribs on the first surface;
- and
- joining the first case and the second case together by melting the ribs,
- wherein in the disposing step, where a load in a first direction orthogonal to an applied surface including a joined surface between the first case and the second case of the housing is applied to the applied surface, a volume of each rib is set so that maximum values of stresses generated in a plurality of regions having the same area of the ribs fall within in a range from a value of 80% of a yield stress value of a material of the ribs to the yield stress value.
A manufacturing method of a housing that includes a first case having a first surface, a second case having a second surface opposite to the first surface, and ribs provided between the first case and the second case, the manufacturing method comprising the steps of:
- disposing the ribs on the first surface;
- and
- joining the first case and the second case together by melting the ribs,
- wherein in the disposing step, a volume of each rib is set so that a volume of each rib provided on the first surface per unit area in a first region is smaller than in a second region where the housing has rigidity higher than that of the first region.
