Claim 3:
4. The actuator unit according to claim 3, wherein:
the brace-side rotational connecting part has a swinging connector for connecting the thigh frame and the lower leg frame to be rotatable around the brace-side pivot axis by being inserted into a brace-side frame attachment hole formed by a thigh frame attachment hole provided in the thigh frame coaxially with the brace-side pivot axis and a lower leg frame attachment hole provided in the lower leg frame coaxially with the brace-side pivot axis;
the swinging connector has an internally threaded member and an externally threaded member, the internally threaded member including a cylindrical part to be inserted into the brace-side frame attachment hole from one side in the user width direction and a flange part extending more radially outward than the brace-side frame attachment hole from the one side in the user width direction of the cylindrical part, the cylindrical part having a screw hole that is open toward a free end side, the externally threaded member having a cylindrical part that has an external thread to be screwed into the screw hole from another side in the user width direction and a flange part that extends more radially outward than the brace-side frame attachment hole from the another side in the user width direction of the cylindrical part; and
the ball stud is provided on the knee-ankle-foot orthosis by being screw-connected to an inner threaded member positioned on an inner side in the user width direction among the internally threaded member and the externally threaded member in place of an outer threaded member positioned on an outer side in the user width direction among the internally threaded member and the externally threaded member.
