Beschreibung
Zusammenfassung:	An electrical device includes a housing, a drive unit arranged inside the housing a substrate arranged inside the housing, and a terminal electrically connecting the substrate with an external portion outside the housing. On the substrate, a circuit driving the drive unit is formed. The terminal includes a terminal protrusion exposed from an inner wall surface of the housing and protruding toward the substrate. The terminal is connected to the substrate at an end portion of the terminal protrusion. The substrate is fixed inside the housing by a first substrate attachment portion and a second substrate attachment portion arranged at a position farther from a connecting portion between the terminal and the substrate than the first substrate attachment portion. The second substrate attachment portion has higher flexibility than the first substrate attachment portion.
