PROBLEM TO BE SOLVED: To provide a motor-assisted vehicle capable of reducing a load applied to an angle detecting part so as to reduce costs and the weight of component items, preventing fluctuation in a detected value by preventing the occurrence of histerisis and improving assist feeling. SOLUTION: In a motor assisted-vehicle including a power unit 83 for outputting a resultant force produced by combining a pedal pressing force inputted to a crankshaft 13 and an assist force from a power motor 82, a pressing force detecting device 86 for detecting a pedal pressing force and a control unit 85 for variable-controlling an assist force from the power motor 82 based on the pedal pressing force detected by the detecting device 86, the power unit 83 includes a planetary gear mechanism disposed coaxial to the crankshaft 13 for inputting a pedal pressing force to a planetary gear 101 and outputting the same from a sun gear 100 and the pressing force detecting device 86 includes a reaction receiving part 125 for pressing a coil spring 130 receiving a reaction from a press arm 100a provided in the sun gear 100 and an angle detecting part 126 for detecting the rotating angle of a turning arm part 100a provided in the sun gear 100, which are provided separately. |
