PROBLEM TO BE SOLVED: To provide a knee-joint exercise assisting apparatus capable of faithfully reproducing the complicated movement of a knee joint.SOLUTION: This knee-joint exercise assisting apparatus includes: a thigh-worn section to be worn on a thigh region; a leg-worn section to be worn on a leg region; a connecting section for rotatably connecting the knee joint-side ends of the thigh-worn section and the leg-worn section; and a drive section for relatively sliding the thigh-worn section and the leg-worn section between the knee joint-side ends in the front/rear direction while relatively rotating them about the connecting section. In the apparatus, the drive section has a circumferential-edge cam, a drive gear arranged on the outer circumferential edge of the circumferential-edge cam, a cam groove formed on the inner circumferential surface of the circumferential-edge cam and a cam follower to be engaged with the cam groove; the circumferential-edge cam, the cam follower and the driving gear are attached to one of the thigh-worn section and the leg-worn section and the other, respectively; and a tooth row where the drive gear is engaged is formed on the outer circumferential edge of the circumferential-edge cam. This apparatus is adapted to produce the rotating movement and the sliding movement when the circumferential-edge cam is rotated between the driving gear and the cam follower by the rotation of the drive gear. |
