Claims

[Scope of utility model registration request]

a rotating shaft supported by the case body via a bearing;
An air compressor formed of an orbiting scroll connected to the rotating shaft to form a spiral wrap, and a fixed scroll fixed to the case body side and having a spiral wrap that meshes with the wrap of the orbiting scroll. In a water circulating scroll compressor that compresses intake air to a predetermined pressure indoors and cools various parts with supplied cooling water, a sealing member is used to connect the cooling water introduction chamber where the cooling water is supplied and the bearing side. A waterproof member having a shape larger than at least an outer diameter of the bearing is fixed to the rotating shaft in a space defined by the bearing, and an opening is formed to communicate the space with the atmosphere. The water-circulating scroll compressor features a waterproof bearing structure.
