Abstract
Brushes () which come into slidable contact with slip rings () having power feeding terminals () electrically connected to a power feeding side include extending portions () extending in the radial direction of a field core (). These extending portions () are bent in a direction away from a coil bobbin (). The third bent portions () located at the ends of the extending portions are electrically connected to the terminal portions () of coil terminals. An outer diameter Rof a mounting recess portion () which stores a power feeding device () of the field core () is smaller than an inner diameter Rof the coil bobbin (). This makes it possible to position the mounting recess portion () at a distance H from the coil bobbin () in the field core () in the arrow A direction, thereby reducing the size of the rotating coil type electromagnetic clutch () in the arrow A-B direction.
