Abstract
To improve convenience of a wheelchair by enabling an outside fitting type of auxiliary power device to be automatically and securely mounted on and removed from the habituated wheelchair, the auxiliary power device, which can be mounted on and removed from the wheelchair and provide power assistance to the wheelchair, comprises photoelectric sensors for detecting positions of predetermined frames of the wheelchair, arms, each having a handle of a shape capable of being engaged with the frames attached to an outer end thereof, and driving motors for displacing the arms. When the frames are determined to be at predetermined positions based on information from the photoelectric sensors, the arms are displaced by the driving motors so as to have the handles engage with the frames.
