A controller for controlling the rotation of a motor is disposed inside a casing of a power unit for transmitting the rotation of the motor to a driving wheel. An induction-type switch for operating the controller is provided inside the casing of the power unit. A power source converter is provided for driving electrical equipment on the vehicle, and is disposed inside the casing of the power unit. Further, an accelerator opening sensor for detecting the magnitude of an output demand for the motor is provided, and is disposed inside the casing of the power unit. This arrangement concentrates the mass into the power unit, and encloses the high voltage system within the power unit.

1. Field of the Invention
The present invention relates to an electric motor-driven vehicle, and particularly to an electric motor-driven vehicle in which the structure of a power unit including a controller and a driver is simplified, and concentration of mass is obtained.
2. Description of the Background Art
The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein:
FIG. 1 is a general side view of an electric motor-driven bicycle according to one embodiment of the present invention;
FIG. 2 is a sectional view of a power unit incorporating a brushless motor;
Hereinafter, the present invention will be described in detail below referring to the drawings. FIG. 1 is a side view of an electric motor-driven bicycle according to the present invention, which has an electric running function for running by a driving force of a brushless motor and a human force running function for running by a human force (tread force) inputted from pedals.
A vehicle body front portion and a vehicle body rear portion are connected to each other through a vehicle body frame 1, and a seat post 2 is erected upward at the rear of a central portion of the vehicle body frame 1. A seat pipe 15 is inserted in the seat post 2, and a seat 8 integrally equipped with a tail lamp 12 and left and right signal lights 13 is provided at the top end of the seat pipe 15.
At the tip end of the vehicle body frame 1, a headlight 11 is provided so as to project forward, and a front carrier 12 is fitted on the upper side of the headlight 11. A front fork 3 is shaft-supported on a head pipe 16 at the tip end of the vehicle body frame, and a handle 9 is fitted to the top end of the front fork 3. A front wheel WF is shaft-supported at the lower end of the front fork 3. Brake levers 14 (right one is not shown) for front and rear wheels are provided at the left and right of the handle 9. A right grip (not shown) of the two grips provided at the left and right ends of the handle 9 functions also as an accelerator grip 58 (See FIG. 6).
