Abstract: A vehicle clutch having a power transmission interruption unit, including: a first rotor connected to a prime mover; a second rotor connected to the first rotor; elastic intermediate members for transmitting power from the first rotor to the second rotor or interrupting the power transmission, the intermediate members being mounted to one of the first and second rotors at first ends and being elastically coupled to a remaining one of the two rotors at second ends; and support members corresponding to the intermediate members, each support member including a head having protrusions and a shank extended from the head, wherein the second ends of the intermediate members are elastically coupled to the first or second rotor by the shanks such that the intermediate members can be released from the elastically coupled state, and the heads of the support members come into surface contact with the intermediate members by the protrusions.

Abstract: An apparatus in a clutchless assembly, which connects or disconnects the transmission of rotational power when an overload equal to or greater than a limit torque occurs in an air conditioner. A rotor 10 is connected to a rotary shaft of an internal combustion engine via a chain or a belt to receive rotational power supplied from the internal combustion engine. A transmitting member 30 is connected to the rotor 10 via a medium 20 to transmit the rotational power to an air conditioner. A plurality of elastic members 40 is interposed between the rotor 10 and the transmitting member 30. When an overload equal to or greater than a limit torque is applied to the air conditioner, the plurality of elastic members 40 disconnects the transmission of the rotational power to the rotor 10. The transmission of power is disconnected without damage to components@ or surrounding components.
