の円筒面としたことを特徴とする磁粉式電磁クラッチ。A driving member having a cylindrical shape and rotating around a center line, a driven member provided inside the driving member concentrically with the driving member and rotatable relative to the driving member, and an excitation coil provided on the driving member. The excitation of the excitation coil causes the gap between the inner friction surface of the drive member and the outer friction surface of the driven member to be filled with magnetic particles, thereby controlling the rotation of the drive member to the driven member. In a magnetic particle type electromagnetic clutch of a type that transmits power to the user, the outer friction surface of the driven member has a shape in which the diameter is large at the center in the width direction and decreases toward both ends;
A magnetic particle type electromagnetic clutch characterized in that the inner friction surface of the drive member is a cylindrical surface having the same diameter over the entire width.
