ELECTRIC BRAKING DEVICE

An electric braking device is an electric braking device in which a rotary motion of a rotation part is converted into a linear motion of a linear motion part, the electric braking device including a sleeve, and an urging part configured to urge a load sensor toward a caliper to which the sleeve is fixed, where the sleeve includes a rotation lock part configured to guide the linear motion of the linear motion part while preventing rotation of the linear motion part accompanying rotation of the rotation part, and a support part configured to support the urging part
