Abstract
In a rotary compressor (10), a first cylinder chamber (37) defined by a front head (31) and a middle plate (38) is formed inside a first cylinder (35), and a second cylinder chamber (42) defined by the middle plate and a rear head (43) is formed inside a second cylinder (40). A first piston (50) and a second piston (60) are housed in the first cylinder chamber and the second cylinder chamber, respectively. The diameters Ds of both the first cylinder chamber and the second cylinder chamber and the thickness Tm of the middle plate satisfy a relational expression expressed as 1 / 30 ≤ Tm / Ds ≤ 1 / 10.
