Abstract

A knee joint (20) includes: a thigh connection portion (22) that is provided on a thigh portion side; a lower leg portion (21) that is connected to the thigh connection portion (22) and rotatably provided around a knee shaft; a knee angle restrictor (24) structured to restrict a relative rotation of the thigh connection portion (22) and the lower leg portion (21) such that a knee angle θ formed by the thigh connection portion (22) with respect to the lower leg portion (21) does not exceed a predetermined lock angle θ_L; and an accommodation space that accommodates a rotational resistor applying resistance to the rotation around the knee shaft in a case where the knee angle θ is equal to or less than the lock angle θ_L.
