Therefore, the coasting amount of the wheelchair (1) for small indoor movements for example is restricted to a small value. As a result, small indoor movements with a small turning radius are made possible, a sufficient coasting amount is secured for an outdoor running. Therefore, along with the possibility of a comfortable running on a level road, a steep uphill running is made easy, and the physical effort of the rider is alleviated.

[ What is claimed is:] [1.]1. A power-assisted wheelchair having a pair of wheels, each adapted to receive a manual input force for turning said wheels and driving said wheelchair, an electric motor for producing assist power for driving said wheels, detecting means for detecting the human power applied to said wheels, and control means for controlling said electric motor in proportion to the human power detected by said detecting means, said control means controlling said electric motor to produce said assist power when the human power is detected by said detecting means and to attenuate said assist power with the lapse of time after said detecting means senses a reduction in the application of human power, the time-attenuation rate of the assist power being determined from a sensed condition.
