1. An electric braking device that generates a braking force on a vehicle by transmitting a rotational torque generated by an electric motor to a linear motion conversion mechanism, converting the rotational torque into a propulsive force in a linear direction of a piston provided in a cylinder by the linear motion conversion mechanism, and pressing a friction material that operates in response to the propulsive force of the piston against a rotating portion that rotates together with a wheel of the vehicle, the electric braking device comprising:
a torque transmission mechanism that mutually transmits the rotational torque between the electric motor and the linear motion conversion mechanism, the torque transmission mechanism cutting off transmission of the rotational torque when the rotational torque in a separation direction in which the friction material separates from the rotating portion has a magnitude equal to or greater than a predetermined value.
