Abstract: The electric braking device is provided with: a pressing member, which has a thread portion with either an internal thread or an external thread and which applies a pressing force on a frictional member; a shaft member, which is rotated by an electric motor and is threadedly engaged with the thread portion; a first spherical surface member, which is separated from the shaft member, being capable of rotating relative to the shaft member around the axis of rotation of the shaft member, and the end surface of which is a spherical surface; and a second spherical surface member, which is in sliding contact with the spherical surface of the first spherical surface member, receives the reaction force of the pressing force, and is restrained from rotating with respect to the axis of rotation of the shaft member.
