Abstract
The invention is to provide a light grating structure for a force feedback device, projecting a light beam from a light source through the pervious parts of a grating body to form pervious areas at a reception end, blocking the light beam by the shade parts of the grating body to form shade areas at the reception end, and increasing the grating distance to move the grating body close to the reception end and increasing the width of the shade part bigger than the pervious part to enable the width of the shade area to equal to the width of the pervious area.
