Abstract
The knee joint weight-bearing apparatus includes a buttock attaching part, a lower-leg attaching part, and two thigh connection units. Each thigh connection unit includes a front thigh link and a rear thigh link. The buttock attaching part, the lower-leg attaching part, the front thigh link, and the rear thigh link constitute a four-bar linkage. The buttock attaching part is configured so that when a user applies his/her weight to the buttock attaching part, a tensile force is generated in the front thigh link and a compressive force acts on the rear thigh link. The rear thigh link includes a gas spring that is configured to be stretchable in a longitudinal direction thereof and generates a resistive force against the compressive force.
