PROBLEM TO BE SOLVED: To prevent interference between a thin portion 42a around a delivery outlet 42 of a front head 22 or the like and a piston 24 during an operation and to prevent occurrence of efficiency reduction or the like, even in a rotary compressor using coolant having a large pressure difference during the operation or a rotary compressor with a relatively large volume. SOLUTION: A recessed part 42b for avoiding interference with a piston 24 in deformation of a peripheral part 42a is formed on an end surface on a cylinder chamber 25 side of the peripheral part 42a of a delivery outlet 42 formed in at least one of a front head 22 and a rear head 23.
