(G) Effect of the Invention As described above, by covering the terminal cover with the main body of the prevention cover, the inside of the protector, the mounting holes and the notches can be shielded from the outside, and the inside of the guide rail of the terminal cover. The retaining part of the concave part of the waterproof cover is locked to the strong end of the presser spring that is inserted into the mounting hole through the notch, and the presser spring can also be used for mounting the prevention cover without using nuts etc. The mounting structure of the cover can be simplified, and the waterproof part of the elastic waterproof cover adheres to the compressor surface by locking the retaining part of the waterproof cover to the bent end of the pressing spring. In addition, the gap between the terminal cover and the compressor surface can be reliably sealed irrespective of the vibration of the compressor. As a result, the waterproofness can be remarkably improved by a simple structure.
