# Apparatus for assisting muscular strength

## Abstract

Provided is an apparatus for assisting muscular strength, including an upper frame; a lower frame configured to be rotatable relative to the upper frame; and a force generating unit configured to provide the lower frame with a force applied in a second rotational direction D2 opposite to a first rotational direction D1 when the lower frame rotates in the first rotational direction D1 relative to the upper frame. The force generating unit includes a frame member configured to define a body of the force generating unit; a first spring accommodated in the frame member; a pressing part disposed at one side of the first spring and configured to press the first spring; and a link part disposed at the other side of the first spring and configured to press the first spring and move in conjunction with a relative rotational motion between the upper frame and the lower frame.
