To prevent the occurrence of seizure between upper and lower end faces of a roller and a cylinder chamber.
A front head 43, a cylinder, and a rear head are fastened by five bolts 48a-48e. A front muffler, the front head 43, and the cylinder are fastened with four bolts 49a-49d. On an upper surface of the front head 43, a recessed part 85 is formed for smoothing a flow of a refrigerant flowing out of the cylinder chamber through a through-hole 84. The recessed part 85 is disposed close to the bolts 48a-48c and the bolts 49a-49c and extends to spaces between each of bolts 48a-48c (bolts 49a-49c). Diameters of the bolts 48b and 48c are smaller than diameters of the bolts 48a, 48d, and 48e. The diameter of the bolt 49 is smaller than diameters of the bolts 49a, 49c, and 49d.
