SLIDE ACTUATOR HAVING A LADDER SHAPE

摘要

PURPOSE: A slide actuator with a ladder shape is provided to add a unit elastic unit of an elastic member, thereby easily realizing a slide actuator with large spring power and long slide stroke. CONSTITUTION: An elastic member(110) includes unit elastic units(110a,110b,110c). A frame member(120) is combined with the elastic member to keep the elastic member in order to independently contract and expand each unit elastic unit. Each unit elastic unit is serially connected. Each unit elastic unit is contracted and expanded in the connection direction of unit elastic units.
