<p>PROBLEM TO BE SOLVED: To provide a compressor capable of controlling resonance and easily miniaturizing a pulley for transmitting driving force from an external part to a rotary shaft, and reducing noise and improving durability. SOLUTION: A lug plate 19 is connected to a drive shaft 16 rotatably supported by a housing of the compressor C through a rubber damper 19A. The lug plate 19 is arranged in a crank chamber 15 in the housing. A recess part 41 is formed on the lug plate 19 and a roller 43 is housed in the recess part 41. The roller 43 separates from a rotation center axis of the lug plate 19 for a designated period and sets up a pendulum motion around an axis in parallel with the rotation center axis. In rotation of the drive shaft 16, resonance due to rotation vibration of the compressor C is controlled by the pendulum motion.</p> |
