摘要： The present disclosure provides a driving device including a stator, a rotor, a housing, a controller, and a sealing member. The sealing member includes a base and protrusions. The protrusion includes a cylindrical portion, a cover portion, a first annular protrusion, and a second annular protrusion. The first and second annular protrusions outwardly protrude from the cylindrical portion. The first annular protrusion is fit in a fit region of the lead hole in a compressed state. The second annular protrusion is offset from the fit region toward the controller.

摘要： A rotor has a rotor core made of a magnetic material, a permanent magnet provided in a magnet insertion hole of the rotor core, and a cushioning material. The cushioning material is provided at a location where a distance between a wall surface of the magnet insertion hole and the permanent magnet is the narrowest, on both sides in a rotational direction with respect to the permanent magnet.
