Abstract:
A rotary compressor for a vehicle, comprising:a housing having an approximate cylindrical inner peripheral surface; a rotor that is rotatable eccentrically to the inner peripheral surface of the housing; a plurality of vanes disposed radially in an outer peripheral surface of the rotor to be slidable on the inner peripheral surface of the housing; a rotation shaft that is disposed to transmit rotation force of a driving source to the rotor; and a connection member that is disposed to be connected to the rotation shaft and the rotor such that the rotation force of the rotation shaft is transmitted to the rotor, wherein: the connection member is connected to the rotation shaft so that the rotation force is transmitted from the rotation shaft to the rotor, when a rotation speed of the rotation shaft is lower than a predetermined value; and the connection member is separated from the rotation shaft so that the rotation force from the rotation shaft to the rotor is interrupted, when the rotation speed of the rotation shaft is equal to or higher than the predetermined value.
