<p>The electric braking device is provided with: a pressing member (PSN), which has a threaded section (NJB) with either an internal thread or an external thread and which applies a pressing force on a frictional member (MSB); a shaft member (SFT), which is rotated by an electric motor (MTR) and screws together with the threaded section; a first spherical surface member (QM1), which is separated from the shaft member, is capable of rotary motion relative to the shaft member around the axis of rotation of the shaft member, and the end face of which is a spherical surface; and a second spherical surface member (QM2), which is in sliding contact with the spherical surface (KJM1) of the first spherical surface member, receives the reaction force of the pressing force, and for which the rotational motion with respect to the axis of rotation of the shaft member is restricted.</p> |
