A walking assistance apparatus comprising:
- a frame configured to mount on a lower leg of a user;
- a sole support connected to the frame, the sole support configured to support a sole of a foot of the user;
- an actuator on the frame, the actuator configured to transfer power;
- and
- a pusher indirectly connected to the sole support via the actuator and the frame and is not directly connected to the sole support, the pusher including a rigid member extending downward from the actuator towards a ground to transmit, based on the power applied from the actuator to the pusher, a force to push against the ground to assist plantar flexion motion of the foot of the user, and wherein
- the actuator includes,
- a first rod movable with respect to the frame, the first rod configured to support a first portion of the pusher;
- and
- a second rod movable with respect to the frame at a higher speed than that of the first rod, the second rod configured to support a second portion of the pusher.
