Claims

[Claims for Utility Model Registration] 1. A drive shaft and a driven shaft rotatably arranged in a housing on the same axis and with their ends adjacent to each other, and a shaft at the end of the drive shaft. a clutch armature disposed in a direction movable but non-rotatable manner; a field having a yoke inner pole and a yoke outer pole having a built-in electromagnetic coil; and a field fixedly mounted in the housing; a clutch rotor fixed to an end, separated from the clutch armature when the electromagnetic coil is de-energized, and adsorbed to the clutch armature when the electromagnetic coil is energized; and a clutch rotor fixed to a side wall of the housing on the driven shaft side. A fixed friction plate is disposed between the housing and the field so as to be movable in the axial direction but not rotatable, and is pressed against the friction plate by the biasing force of a spring when the electromagnetic coil is not energized, so that the electromagnetic a brake armature that moves toward the field side against the biasing force of the spring when the coil is energized and separates from the friction plate; and a brake armature that moves against the biasing force of the spring when the electromagnetic coil is de-energized. An electromagnetic clutch/brake device comprising a manual release device for moving the brake armature toward the field and separating it from the friction plate. 2 A drive shaft and a driven shaft rotatably disposed on the same axis and with their ends adjacent to each other in the housing, and an inner yoke pole and an outer yoke pole each having a built-in electromagnetic coil; a field fixedly attached within the housing; a rotor fixed to an end of the drive shaft; a brake lining fixed to a side wall of the housing on the driven shaft side; and a combination of the rotor and the brake lining. axially movably and non-rotatably engaged on a spline formed on the driven shaft portion located between;
an armature that is brought into pressure contact with the brake lining by a biasing force of a spring when the electromagnetic coil is not energized, and moves toward the rotor against the biasing force of the spring and attracts the rotor when the electromagnetic coil is energized; An electromagnetic clutch/brake device characterized by comprising:
