A driving device, comprising a base and a housing with an axial direction, the housing being polygonal in outer shape and comprising an outer peripheral side wall and a top wall connected to a front side of the outer peripheral side wall, the top wall being provided with an opening to allow light to pass therethrough, wherein,

• the housing comprises a step portion at each corner portion thereof, and the step portion comprises:
• a step horizontal wall extending in a direction intersecting with the axial direction;
• the base comprises a protruding table protruding forward from the front side;
• and
• a table surface of the protruding table is stuck to a rear side surface of the step horizontal wall, wherein
• each of the step portions comprises a first step portion and a second step portion formed in a stepped shape,
• the first step portion comprises:
• a first step vertical wall extending from an outer peripheral side toward a rear side of the top wall, and
• a first step horizontal wall extending from a rear side of the first step vertical wall in a direction intersecting with the axial line;
• the second step portion comprises:
• a second step vertical wall extending from the first step horizontal wall toward a rear side, and
• a second step horizontal wall extending from a rear side of the second step vertical wall in a direction intersecting with the axial line;
• an inner peripheral wall surface of the second step vertical wall and an inner peripheral wall surface of the outer peripheral side wall adjacent thereto form a magnet mounting portion, and
• the rear side surface of the second step horizontal wall is stuck to the table surface of the protruding table.
