[0003] ローターに重量軽減用環状溝が形成された電磁クラッチにおいては、従来、重量軽 減用環状溝の内外周壁はローターの回転中心軸線に対して平行に延在していたの で、使用環境により、例えば車両空調用圧縮機に装着された場合等において、泥水 が電磁クラッチのローターに掛カり重量軽減用環状溝に侵入すると、内外周壁が口 一ターの回転中心軸線に対して平行に延在しているために、泥水中の固形物が環 状溝カゝら排出されず、環状溝内に泥が堆積し、ローターの重量増加やバランスの悪 化を招く可能性がある。 [0003] Conventionally, in an electromagnetic clutch in which an annular groove for weight reduction is formed in the rotor, the inner and outer peripheral walls of the annular groove for weight reduction have been extended in parallel to the rotation center axis of the rotor. Depending on the environment, for example, when installed in a compressor for vehicle air conditioning, if muddy water is caught on the rotor of the electromagnetic clutch and enters the weight reducing annular groove, the inner and outer peripheral walls are parallel to the rotation center axis of the mouth. Therefore, the solid matter in the mud is not discharged from the annular groove, and mud accumulates in the annular groove, which may increase the weight of the rotor and deteriorate the balance.
