する機構が備えられていないφが欠点となっている。However, since the rotor is driven by the engine and the belt, it continues to rotate despite the VC, which prevents the disk from rotating, so a torque that exceeds the engagement torque is generated between the rotor and the disk, causing slippage in the mating section. The viewing screen is blurred. This slipping phenomenon continues as it is in a rounded state that is difficult to detect during four rotations, resulting in a problem of heat generation in the rotor disk IMj. This heat generation generates smoke, burns out the belt, and poses a risk of fire. Traditional,
-One clutch has a disadvantage in that φ is not equipped with a mechanism to prevent the above-mentioned malfunction from occurring.
本発明の目的は前記した電１クラッチの欠点を味去する
１出クラッチを提供することＶｔめる。SUMMARY OF THE INVENTION An object of the present invention is to provide a single-output clutch that eliminates the drawbacks of the electric single-clutch described above.

突起９ｔ−ハブ７の前面に設ける際、板バネ５をハフ７
ＶＣ締結するリベット６と共線されている。When installing the protrusion 9t on the front surface of the hub 7, the plate spring 5 is attached to the hub 7.
It is aligned with the rivet 6 that fastens the VC.

。The protrusion 9 is easily aligned with the leaf spring 5 and the rivet 6.
The shape of the protrusion 9 is also simple and inexpensive. Further, the pulsar 10 includes a pulsar coil 11, a magnet 12, an iron core 13, a pulsar pace 14, and the like, and the magnet 12 forms a magnetic circuit via the iron core 13 and the pulsar pace 14. - The pulsar 10 is fixed to the compressor body 17 by the stay 16 with screws 18. Reference numeral 15 is a pulsator ring. When the compressor rotates, the protrusion 9 cuts the magnetic hook 9 formed in the pulser 10, and an electromotive force is generated in the pulser coil 11, which becomes a rotation pulse and becomes the manual force m of the rotation detector.
