PURPOSE:To prevent vibrating rotation of a driving shaft, by a method wherein, in an enclosure type rotary compressor, both ends of the driving shaft are supported to the interior of an enclosed vessel. CONSTITUTION:A compressor mechanism part is supported to the interior of an enclosure vessel 1 through a frame 3, and a stator 11 of a driving motor is secured thereto. A driving shaft 7 of the compressor mechanism part is supported to an auxiliary bearing 4 having the one end connected to the frame, and the other end is supported to a grooved plate 16, attached to the inner wall of the enclosure vessel, through a steel ball 17. This causes both ends of the driving shaft 7 to be supported by means of a bearing, and prevents vibrating rotation of a driving shaft and reduces production of vibration and noise. |
