Mechanism for deflecting headlamp optical axis without speed reduction gears

A mechanism for deflecting a headlamp optical axis, the mechanism comprising:

• a connecting lever defining a first end and a second end, and having the first end fixed to a headlamp assembly which emits light and which is mounted on an automotive vehicle, a prescribed portion between the first and second ends of the connecting lever being attached in a horizontally movable manner to one predetermined portion of an outside frame which either encloses the headlamp assembly or constitutes a body of the automotive vehicle;
• a bracket having a first end thereof attached to another predetermined portion of the outside frame;
• a motor including a motor body which includes a rotating mechanism, and a rotary shaft which has a rearward portion thereof inserted through the motor body, has a frontward portion thereof sticking out from the motor body, and which has a spiral screw formed on the frontward portion thereof;
• a motor attaching member for attaching the motor to a second end of the bracket such that the motor can move horizontally;
• and
• a traveling block shaped substantially hollow-cylindrical, having a screw formed on its inner circumference so as to threadedly engage with the spiral screw formed on the rotary shaft, and having its outer circumference attached to the second end of the connecting lever in a horizontally movable manner, the traveling block being caused to travel along the rotary shaft when the rotary shaft rotates with respect to the motor body.
