An electromagnetic clutch with brake, comprising: a driven shaft; a drive shaft disposed coaxially and slidably on the outer periphery of the driven shaft; a rotor rotatable together with the driven shaft and having a clutch friction surface at least at an end surface on one side in the axial direction; an armature fixed to the drive shaft so as to be displaceable in the axial direction and, in this state, disposed opposite to the rotor; excitation means (3, 7) which has at least a coil on a stationary member side for supporting rotation of the driven shaft and the rotor and which, when the coil is excited, attracts the armature to press the armature against the clutch friction surface of the rotor and which, when electric power supply is stopped, releases the armature from the rotor; and brake means which is provided between a part on the stationary member side and the rotor, a brake friction surface is provided at an end surface on the other side of the rotor, and a brake means brings the brake element into elastic contact with the brake friction surface from the stationary member side in an axial direction of the drive shaft, a magnetic circuit forming member on the stationary member side is disposed on an outer circumference side of the coil to form a magnetic circuit passing through the rotor and the armature, and the rotor is disposed so as to partly cover the outer periphery of the magnetic circuit forming member, the brake means is constituted such that a base end of a spring is supported on the stationary member side either directly or through a support member, and the brake element set on a tip end side of the spring is put in elastic contact with the brake friction surface provided in the rotor, and restriction means is provided between the brake element and an extension part of the stationary member side extending in the axial direction, the restriction means permitting relative displacements in the axial direction but restraining relative displacements in the rotating direction, of the brake element; characterised in that bake torque is constantly applied to the rotating member side from the stationary member side; the magnitude of brake torque by the brake means is set to be not less than slip torque between the driven shaft and the drive shaft and less than drive torque by the drive shaft. a driven shaft; a drive shaft disposed coaxially and slidably on the outer periphery of the driven shaft; a rotor rotatable together with the driven shaft and having a clutch friction surface at least at an end surface on one side in the axial direction; an armature fixed to the drive shaft so as to be displaceable in the axial direction and, in this state, disposed opposite to the rotor; excitation means (3, 7) which has at least a coil on a stationary member side for supporting rotation of the driven shaft and the rotor and which, when the coil is excited, attracts the armature to press the armature against the clutch friction surface of the rotor and which, when electric power supply is stopped, releases the armature from the rotor; and brake means which is provided between a part on the stationary member side and the rotor, a brake friction surface is provided at an end surface on the other side of the rotor, and a brake means brings the brake element into elastic contact with the brake friction surface from the stationary member side in an axial direction of the drive shaft, a magnetic circuit forming member on the stationary member side is disposed on an outer circumference side of the coil to form a magnetic circuit passing through the rotor and the armature, and the rotor is disposed so as to partly cover the outer periphery of the magnetic circuit forming member, the brake means is constituted such that a base end of a spring is supported on the stationary member side either directly or through a support member, and the brake element set on a tip end side of the spring is put in elastic contact with the brake friction surface provided in the rotor, and restriction means is provided between the brake element and an extension part of the stationary member side extending in the axial direction, the restriction means permitting relative displacements in the axial direction but restraining relative displacements in the rotating direction, of the brake element;
