An electric compressor includes a housing including a first housing portion made of metal, the first housing portion having a first joint surface and a first pin hole, a second housing portion made of metal, the second housing portion having a second joint surface and a second pin hole, a connecting pin made of metal, the connecting pin having a press-fitting portion and a first insertion portion having a first contact portion and removably inserted into the second pin hole, and a first gasket having an insulation property, the first gasket having a first pin insertion hole, the first gasket being interposed between the first joint surface and the second joint surface.

In a structure for mounting a filter in a compressor, a mounting member is connected to the filter. A receiving hole is formed in a housing of the compressor for receiving therein the mounting member. A first fitting portion is formed on an inner circumferential surface of a holding portion of the filter. A second fitting portion is formed on an outer circumferential surface of the mounting member for having fitting relation to the first fitting portion for an overlap distance in a radial direction of the receiving hole. When the mounting member is received in the receiving hole with the fitting relation, the filter is disposed in a fluid passage of the housing. A clearance having a dimension is formed between an outer circumferential surface of the holding portion and an inner circumferential surface of the receiving hole. Minimum value of the dimension is smaller than the overlap distance.

A variable displacement compressor for efficiently cooling and lubricating seals arranged on a rotary shaft. The seals are arranged at end portions of the rotary shaft that project from a housing of the compressor. A first lubrication chamber is defined by a first seal in the housing around the front end portion of the rotary shaft. A second lubrication chamber is defined by a second seal in the housing around the rear end portion of the rotary shaft. A shaft passage extends through the rotary shaft to connect the first and second lubrication chambers. Refrigerant gas including lubricating oil flows from a crank chamber to a suction chamber via the first lubrication chamber, the shaft passage, and the second lubrication chamber. This efficiently cools and lubricates the seals.
