Title: Vane compressor

Abstract: In a vane compressor, a transmission pin is accommodated in a communication hole that provides communication between a first vane slot and a second vane slot. The transmission pin includes a loose-fit portion that is loosely inserted in a recessed portion formed in a bottom surface of each of first and second vanes, a shaft portion, and a flange portion formed between the loose-fit portion and the shaft portion and in contact with the bottom surface. A coil spring is disposed in the communication hole to urge the first vane and the second vane in opposite directions away from each other via the flange portion. The coil spring is disposed around the shaft portion and supported by the flange portion so as to urge and support the transmission pin.
