Patent number: 11036027Abstract: The housing includes a plate-shaped base; and a cover provided with a bottom plate and a side plate, and covers a main surface of the base. The base has in the main surface, a wall part which extends along the peripheral edge of the main surface, and faces the side plate of the cover. The side plate having an opening exposing a portion of the wall part. An adhesive bonding the base and the cover together is provided in a gap between the wall part and the side plate. The cross-sectional area of the gap in a cross section orthogonal to at least one direction from the direction from the wall part exposed from the opening, to either end of the wall part in the length direction, and the direction from the height-direction end of the wall part exposed from the opening, to the main surface of the base, decreases in said at least one direction.Type: GrantFiled: June 7, 2016Date of Patent: June 15, 2021Assignee: Nidec Copal CorporationInventors: Haruka Matsuhisa, Yusuke Ehara
