PURPOSE:To easily make bolt penetrating holes coincide with the screw holes of a cylinder at the time of fastening bolts by shifting, in a specified direction, the bolt penetrating holes, which are provided through a frame and the cylinder head of a compressive element so as to fasten a discharge muffler. CONSTITUTION:A compressor is held inside a closed case 1 in the condition that an electric motor-driven element 2 and a compressive element 3 are connected to each other by a crankshaft 3a. Concerning the compressive element 3, a frame 7 and a cylinder head 8, with which both upper and lower end surfaces of a cylinder 4 are sealed, are fastened to screw holes 9b of the cylinder 4 with bolts 5a, 5b. A discharge muffler 6 is also fastened to the screw holes 9b with the bolts 5a, 5b. In this structure, the bolt penetrating holes 10b of the frame 7, which is provided to be fastened to the cylinder 4 with the discharge muffler 6, are shifted by a specified angle of theta to the circular pitch of screw holes 9b in the direction C which is reverse to the fastening directions of bolts 5a, 5b. |
