Title:
ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2016/006684
Kind Code:
A1
Abstract:
Provided is an actuator in which it is possible to prevent a decrease in plate strength by hydrolysis. This invention is provided with: a diaphragm (30) for dividing the interior of a casing (20) into a negative pressure chamber (21a) and an atmospheric pressure chamber (22a); a plastic plate (40) provided in the negative pressure chamber (21a) so as to be in contact with the diaphragm (30); and an operation shaft (60) having one end connected to the plate (40) and the diaphragm (30), and the other end extending through the atmospheric pressure chamber (22a) to the exterior of the casing (20), the operation shaft (60) being capable of displacement in the axial direction in response to a deformation of the diaphragm (30). The plate (40) is cut off from the atmospheric chamber (22a) by the linkage of the operation shaft (60) to the plate (40) in the negative pressure chamber (21a) through the diaphragm (30).
