Abstract:
    A waterproofing structure which can protect a drive device in the water-tight state and which can establish the water-tight state without raising the manufacturing cost. A waterproofing structure 10 for a drive device 13 including: a power supply unit 11; and a drive unit 12 formed to protrude from one end of the power supply unit 11 and to be operated with an electric power supplied from the power supply unit 11. The waterproofing structure 10 comprises: a power supply unit cover 15 formed to have an opening at its one end and to cover the power supply unit 11 in the water-tight state; and a drive unit cover 17 formed to have an opening at its one end and to cover the drive unit 12 in the water-tight state. The power supply unit 11 includes at its one end a supporting cylinder unit 18 formed to protrude to the side of the drive unit 12, and a protecting cylinder unit 19 formed outside of the diameter of and at a predetermined spacing size from the supporting cylinder unit 18. The drive unit cover 17 has its opening edge portion 16 fitted in the water-tight state between the supporting cylinder unit 18 and the protecting cylinder unit 19 so that the opening circumferential edge portion 27 of the drive unit cover 17 and the protecting cylinder unit 19 can be covered in the water-tight state with the opening edge portion 14 of the power supply unit cover 15.
