Second joints (7, 7) are provided in positions where a seating unit (1) is restrained from swinging relative to leg links (3, 3) due to a force acting on the seating unit (1) from upper limb links (5, 5) through the intermediary of the second joints (7, 7). A motion not intended by a user can be restrained from being generated due to a force acting from the upper limb links (5, 5) provided in the upper limbs.
