Abstract
A sensor device includes a body case provided with an opening, and a body cover assembled to the body case to cover the opening. The body cover has at an outer peripheral portion thereof an overlapping region overlapping a portion of the body case located at a peripheral edge of the opening. The body cover is fixed to the body case by providing a welded portion surrounding the opening using laser-welding at a portion distant from an end surface of the body cover in a boundary of the overlapping region of the body cover and a portion of the body case overlapping the overlapping region.
Claims12
A sensor device comprising:
- a body case provided with an opening;
- and
- a body cover assembled to the body case to cover the opening,
- the body cover having at an outer peripheral portion thereof an overlapping region overlapping a portion of the body case located at a peripheral edge of the opening,
- the body cover being fixed to the body case by providing a welded portion surrounding the opening using laser-welding at a portion distant from an end surface of the body cover in a boundary of the overlapping region of the body cover and a portion of the body case overlapping the overlapping region.
A method of producing a sensor device, comprising:
- disposing a body cover on a body case to cover an opening of the body case and also allow the body cover to have an outer peripheral portion overlapping a portion of the body case located at a peripheral edge of the opening;
- and
- fixing the body cover to the body case by providing a welded portion surrounding the opening so as to bond the body case and the body cover using laser-welding by way of scanning a laser beam along the opening to irradiate therewith a portion distant inward from an end surface of the body cover in a boundary of an overlapping region of the body cover overlapping the portion of the body case located at the peripheral edge of the opening and a portion of the body case overlapping the overlapping region.
