摘要： A driving unit includes a stator, a housing including a tubular section to accommodate the stator, a cover coupled to the housing to block an upper opening of the tubular section, and a bent wire rod defined by a wire to press the stator against the tubular section, the bent wire rod being arranged between a top surface of the stator and a rear surface of the cover while being compressingly deformed along an axis of the stator. The bent wire rod has an annular or substantially annular shape with an opened portion when seen along the axis, and includes projections projecting upward along the axis and depressions projecting downward along the axis being arranged alternately and successively. An elastic force from the bent wire rod causes the stator to receive a downward force along the axis. The stator is pressed against the tubular section to hold the stator in the housing.

摘要： A driving unit includes a stator, a housing, and a spring pin. The housing includes a tubular section and a plate section. The tubular section accommodates the stator and includes a first groove on an inner wall thereof. The plate section has a flat plate shape orthogonal or substantially orthogonal to a central axis of the tubular section, and projects from an outer surface of the tubular section. The first groove is disposed in a peripheral direction of the tubular section within an area facing a joining portion across the central axis, wherein the joining portion is a portion connecting the tubular section to the plate section.
