Claims

[Scope of Claim for Utility Model Registration] (1) The front housing and the rear housing are formed using an aluminum material, and the rear housing is made of an aluminum material so as to cover a cylinder block and both front and rear openings of the cylinder block. When the front side plate and the rear side plate formed by using the rotor are inserted, a boss is provided at the center of each side plate, and a bearing is press-fitted into both the bosses to support the rotor shaft. The rotor shaft has a compression chamber between it and the inner wall surface of the cylinder block, and the rotor is rotatably mounted on the shaft.
A plurality of vanes are inserted into the rotor so as to be able to protrude and retract toward the compression chamber, and a seal chamber is formed in the front housing by facing the boss protruding from the front side plate. In the slide vane type rotary compressor in which a sealing material is fitted between the rotor shaft and the rotor shaft, the front end of the boss protruding from the front side plate can come into contact with one end of the sealing material, and the boss is in contact with the suction refrigerant gas. A structure to prevent bearings and sealing material from falling off in a slide vane rotary compressor, which has a small-diameter boss that can be directly contacted. (2) A bearing in a slide vane rotary compressor according to claim 1 of the utility model registration claim, characterized in that a ring formed using an iron-based material is fitted to the small diameter boss portion; Structure to prevent sealing material from falling off.
