Abstract
A compressor includes a closed container and a compression element welded together at least three, preferably six, welding points. A suction tube for sucking refrigerant gas is attached to the closed container. A first direction and a second direction that are associated with a natural vibration mode of the suction tube do not coincide with a direction in which any two of the welding points are aligned. Accordingly, vibration of the suction tube can be reduced by arrangement of the welding points even if vibration of a motor is transmitted to the compression element.
