<P>PROBLEM TO BE SOLVED: To provide a mounting type power assist apparatus which can be mounted on the body without making a user have the feeling of incompatibility in use. <P>SOLUTION: The assist apparatus 10 comprises a proximal side mounting part 12 to be mounted on the upper arm 100 which is the proximal side body of an elbow joint 104, a distal side mounting part 14 to be mounted on the forearm 102 which is the distal side body of the elbow joint 104, a connecting mechanism 16 for respectively connecting the proximal side mounting part 12 and the distal side mounting part 14, and a motor 18, etc. The motor 18 is offset from the rotating axis L of the elbow joint 104 and arranged on the back side of the upper arm 100. Thus, the projection in a body side direction of the assist apparatus is reduced. Also, the centroid G of the motor 18 is arranged so as to be positioned within the width of the upper arm 100. Thus, when the upper arm 100 is moved, twisting moment is prevented from being applied to the elbow joint 104 and the upper arm 100 by the own weight of the motor 18. Thus, the user is not made to have the feeling of incompatibility in use. <P>COPYRIGHT: (C)2007,JPO&INPIT |
