ELECTRIC ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2021/020075
Kind Code:
A1
Abstract:
A motion conversion mechanism 4 has a rotation member 7 that is rotationally driven by an electric motor, and a linear motion member 8 that moves linearly in the rotational axis direction of the rotation member 7 in conjunction with the rotation thereof. The linear rotation member 8 is provided with a protrusion 12, and a groove 30 into which the protrusion 12 is movably inserted is provided inside a housing 6. The protrusion 12 butts into an end portion of the groove 30 and thereby limits the linear motion of the linear motion member 8.
