ABSTRACT:
An electrically driven cart driven by an electric motor in which a baggage such as golf bag is carried comprises a body frame, a driving source comprising the electric motor, a drive shaft operatively connected to the driving source, a pair of right and left wheels serving as driving wheels which are operatively coupled to be rotatable to both ends of the drive shaft of the motor, a power transmitting mechanism disposed between the drive shaft and the driving wheels to transmit a power of the motor to the driving wheels through the drive shaft, and a carrier secured to the body frame on which a baggage is rested. The power transmitting mechanism performs a differential motion and comprises a pusher which is provided on the drive shaft to be rotatable therewith and a receiver which is provided on the wheels to be rotatable therewith and comes into abutment with the pusher on their coaxial circumferential paths to receive torque from the pusher, the power transmitting mechanism being provided between the drive shaft and each of the wheels. The power transmitting mechanism provides an allowance for rotation of the each wheel such that the wheel side can rotate through a certain angle in advance of the drive shaft side in an advancing direction of the cart.
