Title:
ELECTRIC ACTUATOR, AND ELECTRIC BRAKING DEVICE FOR VEHICLE USING SAID ELECTRIC ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2021/261590
Kind Code:
A1
Abstract:
An electric actuator DN comprises: "an input member BI which is rotationally driven by an electric motor MT and has a first rotation stop part Ma on an inner periphery Mn"; "an output member BO which has, on an outer periphery Mg, a second rotation stop part Mb that can mesh with the first stop part Ma, and a first screw part Na"; and "a linear motion member BH having a second screw part Nb that can mesh with the first screw part Na." Both a screw mechanism NJ and a rotation stop mechanism MD are formed on the outer periphery Mg of the output member BO. Consequently, the radial direction and axial direction dimensions of the electric actuator DN are shortened.
