STATOR ANCHORING STRUCTURE AND DRIVE DEVICE

A driving unit 1 includes a stator 13, a housing 3, and a spring pin 15. The housing 3 includes a tubular section 11 and a plate section 29. The tubular section 11 accommodating the stator 13 has a first groove on an inner wall 21 thereof. The plate section 29 has a flat plate shape substantially orthogonal to a central axis P of the tubular section 11, and projects from an outer surface of the tubular section 11. The first groove is disposed in a peripheral direction Q of the tubular section 11 within an area facing a joining portion B across the central axis P, in the joining portion B the tubular section 11 and the plate section 29 being joined.
