Patent abstract
An actuator is provided to generate an ultrafine stroke according to a fluid input pressure such as air pressure or the like. A throughhole 12 is formed in a center part of a body 10 so as to traverse a body 10 having plural notches 21–24 formed vertically on the body, a depression 13 is formed at the end of the body 10, and a rod 17 connected with a pressure plate 16 housed and held in the depression 13 is disposed in this throughhole 20. When an input pressure is applied to the pressure plate 16 via a diaphragm 19, an output point P generates a stroke due to the elastic deformation of a join part at the end of the notches 21–24.
