In this electric-powered braking device, the rotational power of an electric motor (MTR) is inputted to an input member (INP) and is transmitted to a pressing member (PSN) via a reduction gear (GSK), a shaft member (SFT), and a threaded member (NJB). The pressing member (PSN) presses a friction member (MSB) against a rotating member (KTB) and generates braking torque against a wheel. Here, the reduction gear (GSK) reduces the rotational power of the input member (INP) using at least two different rotating shafts (Jin, Jsf). A ratchet gear (RCH) is secured to the input member (INP), and this engages an interlocking pawl (Tsu) of a solenoid (SOL), thereby restraining the rotation of the input member (INP) corresponding to the direction in which the pressing member (PSN) moves away from the rotating member (KTB). |
