Abstract: A photoelectric sensor including at least any one of a light projecting unit for emitting light and a light receiving unit for detecting light includes a substrate on which at least any one of the light projecting unit and the light receiving unit is mounted, a cover which has a protecting portion facing the substrate and for protecting the substrate and a side wall extending from a periphery of the protecting portion, and a sealing member which seals at least any one of the light projecting unit and the light receiving unit that is mounted on the substrate, in which the cover has a protruding portion on a surface which is positioned outside a side surface of the substrate and intersects an extending direction of the side wall, and the protruding portion is in contact with the sealing member.

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.

Abstract: A sensor device includes: a casing provided with an opening; a cover member covering the opening; a gasket interposed between the cover member and the casing; and a fixing cover which fixes both the gasket and the cover member to the casing. A plurality of welded portions bonding the casing and the fixing cover together are provided in a region outside the cover member such that the welded portions are distant from each other.

Abstract: Provided is a cable disconnection preventing structure or the like in which a conducting wire is not cut at a connecting portion at which a distal end of a conducting wire is connected to a substrate or the like even when a cable is pulled. The cable disconnection preventing structure (100) comprises a case (30) and a conducting wire fixing member (20) which fixes a conducting wire (2) exposed from a sheath (1) to the sheath (1) at one end portion of the cable (10).
