To control the attitude of a front vehicle body during stopping by a simple structure in a rocking type small tricycle connecting the front vehicle body in which a front wheel is steerably suspended and a saddle seat is installed, and a rear vehicle body in which right and left rear wheels are suspended, through a rearwardly-downward inclined rocking connection mechanism disposed on a vehicle body centerline in a vehicle width direction.
A switching mechanism 31 switches between a state where an output of a regular and reversible rotation controllable electric motor 27A is inputted to a differential gear mechanism 30 including a side gear 55 connected to a pair of right and left driving axles 29L and 29R, respectively, and a state where the output of the electric motor 27A is transmitted to one 29R of the two driving axles 29L and 29R. A control unit controls the operation of the switching mechanism 31 so that the output of the electric motor 27A is transmitted to the driving axle 29R according to a lateral inclination of the attitude of the front vehicle body during stopping, and in that state, also executes the regular and reversal rotation control of the electric motor 27A.
