PROBLEM TO BE SOLVED: To provide a driving device which includes a motor part and a controlling unit, is fixed to an attachment object, and enables reduction of the number of portions to which seal means are applied.SOLUTION: In a driving device 1, a motor part 30 is housed at the inner side of a cylinder part 11 of a cup shaped motor case 101 and a bottom plate part 121 is fixed to a gear box 801 which is an attachment object. A lid body 201 fits in an inner wall 115 of the cylinder part 11 at the inner side of an opening edge part 131 of the motor case 101. A controlling unit cover 70 is fixed to an end part of the motor case 101, which is located at the opposite side of the gear box 801, and covers a controlling unit 50. An O ring 41 serving as first seal means seals a space between the motor case 101 and the gear box 801 in a fluid-tight manner. An adhesive 40 serving as second seal means seals a space between the controlling part cover 70 and the motor case 101 in a fluid-tight manner. The structure reduces the number of portions, to which the seal means are applied, to two portions.SELECTED DRAWING: Figure 3 |
