Since a torsion spring 87b providing torque is coupled to the disc plate 85, torque can be provided to the case 81. At this time, it may correspond to a muscle power assistance mode.

When the case 81 is moved upward in FIG. 6 by the operation of the lever 83, the holder pin 86a coupled to the case 81 comes out of the pin hole 86b of the disk plate 85 and the case ( 81) can be driven separately from the disk plate 85 (see FIG. 7). That is, since the torque of the torsion spring 87b coupled to the disk plate 85 is not transmitted to the case 81, the user can operate freely without receiving any force. In this case, it may correspond to an autonomous operation mode.

Referring to FIG. 8 , the movable range of the user's motion may vary according to the position where the holder pin 86a and the pin hole 86b are coupled by the lever 83 .

For example, as shown in FIG. 8 (a), when the arm support 71 is positioned in one direction parallel to the ground, when the holder pin 86a and the pin hole 86b are coupled, downward in the one direction around the axis of rotation As it moves, a large torque can be received by the torsion spring 87b. A range from one direction to a point rotated downward by the maximum movable range angle may be the user's movable range. The maximum movable range angle may vary depending on the elastic force and coupling structure of the torsion spring 87b.

As shown in FIG. 8 (b), when the holder pin 86a and the pin hole 86b are coupled in the other direction forming an angle of about 45 degrees with the ground, the torsion spring can move downward in the other direction around the axis of rotation ( 87b) can receive a large torque. A range up to a point rotated downward by the maximum movable range angle from the other direction may be the user's movable range. The maximum movable range angle may vary depending on the elastic force and coupling structure of the torsion spring 87b.
