Title:
ELECTRICALLY DRIVEN ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2017/163908
Kind Code:
A1
Abstract:
Provided is an electrically driven actuator 1 comprising a housing 2 in which a motor A and a motion conversion mechanism B are accommodated and held. The motion conversion mechanism B has: a threaded shaft 33 disposed coaxially with the center of rotation of a rotor 24; and a nut member 32 rotatably fitted on the outer periphery of the threaded shaft 33. The electrically driven actuator 1 is configured such that the axial rectilinear movement of the threaded shaft 33 caused by the rotation of the nut member 32 causes an operation section D mounted to the threaded shaft 33 to axially operate an object to be operated. A terminal section D (terminal body 50) which holds an electrical component has a cylindrical section 50A gripped from both axial sides by members constituting the housing 2. An opening 50c providing communication between the inside and outside of the housing 2 is provided in the cylindrical section 50A. The threaded shaft 33 is formed in a hollow shape having an axially extending through-hole 33c.
